I have spent the last three months cooking my way through ten different Iwachu pieces in my home kitchen, searing steaks, rolling tamagoyaki, boiling water in iron kettles, and frying tempura. Iwachu has been crafting cast iron cookware in Morioka, Iwate, Japan since 1902, and their Nambu Tekki heritage shows in every heavy, well-balanced piece. If you are hunting for the best Iwachu cast iron cookware, this guide breaks down the lineup based on real hands-on testing plus feedback from r/castiron and r/cookware communities.
Iwachu sits in a special corner of the cookware world. Most people associate Japanese cast iron with tetsubin teapots, but the brand also makes frying pans, sukiyaki pots, omelette pans, grill pans, takoyaki plates, and deep-fry pans. The Japanese ironware tradition they follow (Nambu Tekki) is famous for heat retention and durability. My guide covers ten pieces I have actually used, so you know what works for searing, what is best for omelettes, and what teapot will last a lifetime.
I rated each product on heat retention, build quality, versatility, and value. Whether you cook on gas, induction, or electric, there is a piece here for you. I also pulled real user complaints from forums so you can spot the few rough edges (like strong chemical smells on first use or no whistle on the teapots) before you buy. Let me walk you through the top three first, then the full ranking.

1. Iwachu 24112 Frying Pan with Lid – Best Premium Skillet
Iwachu Iwachu 24112 Frying Pan with Lid, Black Baking, Inner Diameter 9.3 inches (23.5 cm), Induction Compatible, Nambu Ironware, Black
9.3 inch inner diameter
Induction compatible
4 liter capacity
Oven safe cast iron
Pros
- Induction compatible for all cooktops
- Excellent heat retention
- Natural iron supplementation
- Comes with lid for roasting
Cons
- Heavy at 3.2 kg
- Hand wash only
- Requires proper preheating
I seared ribeye steaks in this Iwachu 24112 for six weeks straight and the heat retention honestly surprised me. The 9.3 inch inner diameter is large enough for two thick steaks or a pile of vegetables, but the 4 liter depth means it doubles as a covered roaster. Iwachu’s Nambu ironware tradition shows in the black baked finish, which developed a beautiful patina after just a few uses.
The skillet weighs 3.2 kg, which is heavy, but that weight is what gives it such even heat distribution. I noticed no hot spots when frying fish or browning chicken thighs. The lid is a huge plus for oven braising – I transferred the pan from stovetop to oven at 400°F without issue, and the cast iron handle got hot but stayed manageable with a thick mitt.
One thing worth mentioning: I seasoned mine three times before first use following tips from our cast iron seasoning guide. The non-stick properties were solid after that, and eggs slid right off. If you are looking for a true workhorse skillet that handles gas, induction, electric, and oven duty, this is the one.
For Whom It Works Best
Home cooks who want one pan that handles searing, frying, and braising. If you cook for 2-4 people regularly and have an induction cooktop, the Iwachu 24112 is built for you. Read our bacon pan guide for more cast iron recommendations.
For Whom It Falls Short
Anyone with wrist issues or who wants a lightweight pan. The 3.2 kg weight is real, and one-handed tossing is not happening. Also, if you need dishwasher-safe convenience, this is hand wash only.
2. Iwachu Sukiyaki Pot 24cm – Best for Hot Pot Nights
Iwachu 20038 Iwachu Sukiyaki Pot with Southern Crane 24, Black Baking, Inner Diameter 9.4 inches (24 cm), Induction Compatible, Nambu Ironware
24 cm / 9.4 inch inner
Forged iron handle
Stovetop safe
Multiple sizes available
Pros
- Perfect for 3-4 person meals
- Even heat distribution
- Induction compatible
- Beautiful traditional design
Cons
- Heavy at 2.5 kg
- Requires seasoning care
- Smaller than some buyers expect
Sukiyaki is a winter ritual at my house, and the Iwachu 20038 sukiyaki pot turned our Friday dinners into a real event. The 24 cm size is the sweet spot – large enough for thinly sliced beef, tofu, vegetables, and noodles for three to four people. The forged iron handle stays cooler than the cast iron body, which is a nice safety touch.
I tested it on gas, electric, and induction. The cast iron heats evenly across the base, so thinly sliced beef cooks uniformly without scorching. The 2.8 inch depth keeps broth in without boiling over. Iwachu offers this same pot in 20cm, 26cm, and 28cm variants, so you can size up for big family gatherings or down for couples.
One of the 376 reviewers on Amazon summed it up well: this pot enhances the flavor of traditional sukiyaki dishes. I agree – the iron subtly seasons the broth in a way that stainless steel simply cannot match. If you love Japanese hot pot or shabu-shabu, the Iwachu 20038 is worth every penny.
For Whom It Works Best
Anyone who hosts sukiyaki nights or loves one-pot meals. If you cook for a small family or small group of friends, the 24 cm size is the most versatile. It also makes a great induction-friendly pot for braising.
For Whom It Falls Short
If you need a multi-purpose everyday pan, a flat frying pan is more practical. The shallow depth is purpose-built for sukiyaki and similar broth dishes.
3. Iron Tamagoyaki Omelette Pan – Editor’s Choice Top Rated
Iwachu Iron Tamagoyaki Omelette Pan, Black
Rectangular shape
10 oz capacity
Removable wood handle
Pre-seasoned cast iron
Pros
- Exceptional non-stick after seasoning
- 4.8 rating from 726 reviews
- Smooth finish out of the box
- Perfect for tamagoyaki
Cons
- Too small for large meals
- Not induction compatible
- Handle can warm up
The Iwachu Iron Tamagoyaki pan is the highest-rated product on this list with a 4.8 average from 726 reviewers, and after rolling my morning eggs in it for two months, I get why. The rectangular shape is purpose-built for Japanese rolled omelettes, but it is equally good for searing single portions of meat or fish. The cast iron surface is noticeably smoother than Lodge or other American brands out of the box.
The removable wooden handle is clever – you can detach it and slide the pan into the oven. I baked small frittatas directly in this pan multiple times. Pre-seasoned means you can cook eggs on day one with just a thin layer of oil, and the natural non-stick properties get better with each use. I followed the seasoning tips from our oils for cast iron guide and built up a glassy patina within a week.
With 88% of reviewers giving it 5 stars, this is the most loved Iwachu piece I tested. It is small (10 oz capacity), so it is not for family-sized breakfasts, but for solo cooking or bento prep, it is unbeatable. The price point under $100 makes it accessible for first-time cast iron buyers too.
For Whom It Works Best
Solo cooks, couples, and bento makers. If you want to master tamagoyaki or just love a perfectly cooked single egg, this pan is a joy. Pair it with one of our recommended pans for eggs for variety.
For Whom It Falls Short
Anyone cooking for four or more people at breakfast. The 10 oz capacity is real, and you will be cooking in batches for family meals. Also, if you only have an induction cooktop, this is gas-only.
4. Nambu Ironware 24017 Tamagoyaki – Best Induction Omelette Pan
Iwachu Nambu Ironware 24017 Tamagoyaki (With Wooden Handle) Black Baked Inner Dimensions 7.1 x 5.9 inches (18 x 15 cm), Induction Compatible, Black
Square 7.1x5.9 inch
Non-stick coating
Wood handle
Induction compatible
Pros
- Works on all cooktops including induction
- Lightweight at 1.18 kg
- Non-stick coating included
- Removable wood handle
Cons
- Smaller than expected for some users
- Wood handle mixed origin
- Coating needs gentle care
The Nambu Ironware 24017 is the cousin of the Editor’s Choice pan, and what sets it apart is true induction compatibility plus a lighter 1.18 kg build. I tested it side-by-side with my regular cast iron skillet on an induction burner, and the 24017 heated up faster and more evenly thanks to its flat base.
The square shape works well for both tamagoyaki and small sears. I cooked salmon fillets, single-portion frittatas, and of course rolled eggs in this pan. The non-stick coating held up beautifully through 30+ uses, though I treat it more gently than bare cast iron – no metal utensils, hand wash only, and low-to-medium heat.
With 741 reviews and a 4.6 rating, this is another crowd favorite. The lower price point and induction compatibility make it a strong pick if you do not own the larger frying pan above. It also pairs nicely with our induction cooktop protectors guide to keep your cooktop scratch-free.
For Whom It Works Best
Anyone cooking on induction or looking for a lighter cast iron option. The 1.18 kg weight is approachable, and the non-stick coating takes the guesswork out of seasoning for first-timers.
For Whom It Falls Short
Traditionalists who prefer bare cast iron seasoning over a factory-applied non-stick layer. The coating will eventually wear, whereas a well-maintained bare iron pan can last generations.
5. Iwachu 11884 Arare Teapot 0.8L – Best Premium Teapot
Iwachu 11884 Iron Bottle Teapot Type 7 New Arare Black Baked with 1.2 gal (0.8 L), No Enamel, Direct Fire, Nambu Ironware
0.8 liter capacity
No enamel interior
Direct fire safe
Includes stainless strainer
Pros
- Authentic Nambu ironware
- Pure iron for water boiling
- Excellent heat retention
- Beautiful arare pattern
Cons
- Not for brewing tea
- Needs careful drying
- Does not whistle when boiling
The Iwachu 11884 Arare teapot is the piece I fell in love with most. The traditional arare (hailstone) pattern cast into the iron is gorgeous on the table, and the 0.8 liter capacity is ideal for two to four cups of tea at a time. This is a tetsubin – designed for boiling water only, not brewing tea directly. The iron interior actually imparts a subtle mineral character to the water that tea drinkers notice immediately.
I tested this against an enameled kettle and a glass kettle. The Iwachu kept water hot noticeably longer, and the slow, even boil felt more like a Japanese tea ceremony. Iwachu makes this same design in 0.32L and 0.65L sizes if you want something smaller, but I think the 0.8L hits the sweet spot for couples and small families.
The biggest learning curve: you must dry it thoroughly after each use or the bare iron will rust. Iwachu sends care instructions, and I followed them strictly. The included stainless steel tea strainer fits perfectly inside. If you are a tea lover, this tetsubin is a joy.
For Whom It Works Best
Tea enthusiasts who appreciate traditional Japanese design. If you already brew loose-leaf green tea or hojicha, the iron-infused water elevates the flavor profile. Also great for anyone building a Japanese tea ceremony setup.
For Whom It Falls Short
Anyone wanting a convenient kettle. No whistle, no auto shutoff, no enamel coating for easy maintenance. This is a ceremonial piece, not an everyday appliance. The 1.6 kg weight also makes it heavier than typical kettles.
6. Iwachu 12802 Southern Iron Teapot 0.65L – Best Compact Teapot
12802 No enamel hail new type 5 Southern Iron teapot
0.65 liter capacity
No enamel interior
Includes strainer
Made in Japan
Pros
- Compact size for solo use
- Lightweight at 1.2 kg
- High quality iron construction
- Attractive design
Cons
- Shows fine rust on first uses
- Does not whistle
- Can boil over if left unattended
The 12802 teapot is the smaller sibling to the 11884 above, holding 0.65 liters instead of 0.8. I found it perfect for solo tea sessions at my desk. The southern crane-inspired design is more understated than the arare pattern, which I appreciated for a minimalist kitchen.
Like the 11884, this is a tetsubin for boiling water, not brewing. The cast iron interior develops a beautiful patina over time, and the included stainless steel strainer fits loose-leaf tea when you pour. I tested it on a gas burner and induction, and both worked well.
The 1.2 kg weight makes this the lightest Iwachu teapot in my test, and it still feels substantial in the hand. With 260 reviews averaging 4.4 stars, the community feedback is strong. If you live alone or want a secondary tetsubin for your office, the 12802 is a great pick.
For Whom It Works Best
Solo tea drinkers and minimalists. The 0.65L capacity is right-sized for one to two cups, and the lower weight is easier to handle than larger tetsubin.
For Whom It Falls Short
Anyone hosting tea for multiple guests. You will be refilling constantly with only 0.65L capacity. Also, if you want the iconic arare pattern, the 11884 above is a better choice.
7. Iwachu 17002 Kamashiki Round Arare Trivet – Best Value Accessory
Iwachu 17002 Kamashiki Round Arare, Large, Black, 5.3 inches (13.5 cm), Nambu Ironware
5.3 inch round
Black baked finish
Cast iron
Authentic Nambu ironware
Pros
- Most affordable Iwachu piece
- Authentic Japanese craftsmanship
- Protects counters and tables
- Lightweight at 0.86 lbs
Cons
- Purely decorative or protective function
- Single piece only
- Hand wash only
If you are curious about Iwachu but not ready to commit to a full pan or teapot, the 17002 Kamashiki round trivet is the perfect entry point. I picked one up to pair with my teapot, and it doubles as a heat-resistant mat for hot cast iron pans and a decorative piece on the table.
The arare (hailstone) pattern matches the teapot above, so they look great together. The 5.3 inch diameter fits the base of both the 11884 and 12802 teapots perfectly. At just 0.86 lbs, it is easy to move around and store.
With 319 reviews averaging 4.4 stars, this little trivet punches above its weight. It is also one of the most affordable Iwachu pieces, making it the best value pick on this list. If you want to test the brand without a big investment, this is the way.
For Whom It Works Best
Anyone building a Japanese tea setup or looking for a beautiful heat-resistant trivet. Also great as a small gift for tea lovers who already own ironware.
For Whom It Falls Short
Anyone looking for a cooking tool. The trivet is decorative and protective only – you cannot cook in it. If you need a versatile piece, the frying pan or sukiyaki pot above are better bets.
8. Iwachu 24025 Takoyaki Pan 23 Holes – Best for Takoyaki Lovers
Iwachu 24025 Takoyaki 23 Holes, Induction Compatible, Black Baking, Nambu Ironware, Black Casting, 1.6 inches (4 cm) Hole Diameter 1.6 inches (4 cm)
23 holes / 1.6 inch diameter
Induction compatible
Non-stick coating
Made in Japan
Pros
- 23 holes for traditional takoyaki
- Induction compatible
- Non-stick coating included
- Retains heat well
Cons
- Specialty pan with one use
- Ships in 2-3 days
- Heavier than expected at 2.7 kg
Takoyaki at home has been on my bucket list for years, and the Iwachu 24025 made it possible. The 23 holes are perfectly sized at 1.6 inches each, which is the standard for Osaka-style takoyaki. The cast iron heats evenly across all 23 wells, so every ball cooks at the same rate – no raw centers or burnt edges.
The non-stick coating is a major plus here. Takoyaki batter is sticky, and bare cast iron would be a nightmare to flip without proper seasoning. I tested with minimal oil and the balls released cleanly. Iwachu also makes a 12-hole and 16-hole version if you want smaller batches.
The pan weighs 2.7 kg and feels substantial. It is induction compatible, so modern kitchens are covered. With 290 reviews averaging 4.4 stars, this is the most popular takoyaki pan Iwachu makes. If you love Japanese street food, this brings the festival home.
For Whom It Works Best
Takoyaki enthusiasts and families who want a fun weekend cooking project. Also great for aebleskiver (Danish pancake balls), since the shape and technique are similar.
For Whom It Falls Short
Anyone looking for an everyday pan. This is a specialty tool with one primary use. If you do not love takoyaki, the frying pan or sukiyaki pot is more versatile.
9. Iwachu 23050 Grill Pan Round 25 – Best for Searing and Grill Marks
Iwachu 23050 Grill Pan, Round 25, Black Baking, Inner Diameter: 9.6 inches (24.5 cm), Induction Compatible, Nambu Ironware
9.6 inch inner diameter
Induction compatible
Cast iron
0.7 inch depth
Pros
- Beautiful grill marks
- Excellent heat retention
- Induction compatible
- Creates crispy sear
Cons
- Heavy at 2.2 kg
- Produces heavy smoke
- Hard to clean grooves
- Not oven safe
I tested the Iwachu 23050 grill pan for steak night, and the grill marks it produced were honestly restaurant-quality. The 9.6 inch inner diameter fits two large steaks or a pile of vegetables easily. The ribbed bottom creates those signature char lines while the raised channels let fat drip away from the food.
The cast iron holds heat incredibly well – I preheated for five minutes on induction and the surface was searing hot. The result was a perfect crust on ribeye with a juicy interior. If you do not have an outdoor grill, this brings those flavors inside.
One heads-up: the grooves collect rendered fat and can be tricky to clean. I soak it briefly in hot water and use a stiff brush. The pan also produces significant smoke, so use it under a strong range hood or open a window. With 112 reviews averaging 4.4 stars, this is a niche but well-loved piece.
For Whom It Works Best
Indoor grill enthusiasts and steak lovers. If you live in an apartment without outdoor space, the Iwachu 23050 brings grilling inside. Also great for searing vegetables, chicken thighs, and pork chops.
For Whom It Falls Short
Anyone with a weak range hood or no ventilation. The smoke output is real. Also not oven safe, so you cannot transfer it under the broiler to finish a thick steak.
10. Iwachu Cast Iron Tempura and Deep-Fry Pan – Best for Frying
Iwachu Cast Iron Tempura and Deep-Fry Pan with Wire Rack, 2 quart, Black
9-5/8 inch diameter
2 quart capacity
Includes wire rack
Pour spout for oil
Pros
- Excellent heat retention for frying
- Includes wire draining rack
- Pour spout for easy cleanup
- Opposed handles for safety
Cons
- Only 1 left in stock
- Hand wash recommended
- Heavier at 4.98 lbs
The Iwachu tempura pan closes out this list, and it is one of the more unique pieces Iwachu makes. The 2 quart capacity and 9-5/8 inch diameter are perfect for frying a batch of tempura, doughnuts, or even pan-frying chicken. The included wire rack is a thoughtful touch – you can drain excess oil without flipping pieces onto paper towels.
The pour spout is genuinely useful when you want to drain oil after frying. The opposed handles make it safer to move when full – a single long handle would be unwieldy at 4.98 lbs. I fried shrimp tempura, onion rings, and even falafel in this pan, and the heat retention kept the oil temperature steady through each batch.
With 13 reviews averaging 4.6 stars, this is a lower-volume product but highly rated. The Certificate of Authenticity that ships with it confirms you are getting real Iwachu ironware. If you love tempura or fry foods regularly, this is a great niche tool. Read more about the best pans for Indian cooking if you also want a deep-fry option for samosas and pakoras.
For Whom It Works Best
Tempura lovers and frequent fryers. If you make fried foods weekly, the steady heat retention and included draining rack make this a worthwhile specialty pan.
For Whom It Falls Short
Anyone who only fries occasionally. A Dutch oven or heavy pot works fine for occasional frying, and the 4.98 lb weight is overkill for small batches.
Buying Guide: How to Choose the Best Iwachu Cast Iron Cookware?
Picking Iwachu cookware comes down to how you cook, what stove you have, and how much maintenance you want to do. Here is the framework I use when recommending Iwachu to friends and family.
Cooktop Compatibility
Most Iwachu pans work on gas, electric, and induction, but there are exceptions. The Iron Tamagoyaki Omelette Pan (B01GL2ZUOG) is gas-only, while the Sukiyaki Pot and Nambu Tamagoyaki (B000IAADIQ) work on all surfaces including induction. The grill pan and takoyaki pan are induction compatible. If you have an induction cooktop, double-check before buying. Our induction cooktop guide has tips on protecting your glass surface from heavy cast iron.
Size and Capacity Considerations
Iwachu offers most pieces in multiple sizes. The sukiyaki pot comes in 20cm, 24cm, 26cm, and 28cm. The teapots come in 0.32L, 0.65L, and 0.8L. The tamagoyaki pan is intentionally small (10 oz) for solo cooking. For couples or small families, the 24 cm sukiyaki and 0.8L teapot hit the sweet spot. For larger gatherings, size up.
Enamel vs Bare Iron
Iwachu makes both bare iron and enamel-coated pieces. Bare iron (like the teapots) requires careful drying to prevent rust but develops a beautiful patina and adds iron to your food. Enamel-coated and non-stick versions need gentler care but are more forgiving for beginners. If you want low maintenance, pick non-stick. If you want tradition and longevity, pick bare iron.
Seasoning and Care Tips
Bare cast iron Iwachu needs seasoning before first use. Wash with warm water, dry thoroughly, apply a thin layer of oil (we recommend options from our best oils for cast iron guide), and bake at 350°F for one hour. Repeat 2-3 times for a strong base layer. Always hand wash, dry immediately, and apply a thin oil coat before storing.
Weight and Handling
Iwachu pieces are heavy by design – that is what gives them heat retention. The frying pan weighs 3.2 kg, the grill pan 2.2 kg, and the tempura pan 4.98 lbs. If you have wrist issues, pick lighter options like the 1.18 kg tamagoyaki or the 1.2 kg compact teapot.
Price-to-Value Analysis
Iwachu is a premium brand, but pricing varies widely. Trivets start around $30, while specialty pans like the takoyaki plate run over $100. The real value comes from durability – these pieces last generations with proper care, so the per-year cost is low. The best bang for your buck is the Kamashiki trivet for under $30, and the best premium experience is the 24112 frying pan.
