8 Best Japanese Cast Iron Teapots in 2024 (Tested & Reviewed)

Share this post:

Japanese tea culture has a quiet, transcendent quality that the modern world needs. Steeped in tradition, it invokes a more peaceful time.

If you’re ready to enjoy the tranquility of a perfect brew served with artisanal flair, the Japanese cast iron teapots reviewed in this guide are as sophisticated as they are practical.

Our recommendations for Best Japanese Cast Iron Teapots:

History of Tetsubin — Japanese Cast Iron Teapot

Tetsubin is a traditional Japanese tea kettle featuring a spout, lid, and arching handle. Made exclusively of cast iron, their origin isn’t entirely clear, but researchers suggest they were developed from primitive, sixteenth-century water-bearing pots.

Popularized by China’s introduction of coarse loose leaf — a departure from the powdered matcha favored in Japan — Tetsubin were designed to brew tea and water on a brazier, or hibachi, over coals.

In the 19th century, modern stoves made them more collectible than practical, and styles evolved from simple and unadorned to artistic masterpieces. Today, they bring a touch of tradition back to our busy lives.

Advantages of Japanese Cast Iron Teapots

Space-age materials make great mattresses, but here’s why cast iron makes a better teapot:

Virtually Indestructible: Cast iron is the quintessential forever cookware. It’s heavy but so durable it survived cross-country travel with the pioneers. There are vintage pieces on the market today that look like new. Porcelain and glass teapots are lucky to survive years, much less decades. Extreme overheating can cause warping and pouring ice-cold water over hot, dry iron can cause cracks. But if you treat your kettle gently and keep it clean and dry between uses to ward off rust, it will serve you — and perhaps the next generation — for a lifetime.

Heats Evenly and Retains Warmth: Cast iron heats evenly, extracting more nutrients and subtle flavors from your favorite loose leaf tea. Heat retention is superb, so your second cup will be as warm and comforting as your first.

Chemical-Free: Health experts agree — pure cast iron is one of the world’s safest cooking materials. It’s an alloy containing iron and carbon plus traces of healthy, naturally occurring substances like sulfur, manganese and phosphorus. Unlike “advanced” cookware, it contains no unpronounceable additives or chemicals known to cause cancer. If you want your tea to be as safe, wholesome and nutritious as possible, a cast iron kettle is among your best options.

Welcomed Source of Dietary Iron: Iron is a dietary mineral that supports oxygenation — your body needs it to survive. Yet low iron remains the world’s most common nutritional deficiency. Cooking food in a cast iron pan can double or even triple its iron content — a bonus for vegetarians who frequently suffer from iron deficiency anemia. Brewing tea in a non-coated cast iron kettle has similar benefits.

Offers a Traditional Tea Experience: Traditional Japanese tea ceremonies are symbolic of peace and harmony. They’re a bonding opportunity and a way for friends to take a break from their worries. So whether you’re hosting a simple afternoon tea or preparing for a spiritual tea ceremony, you can honor the tradition with a Japanese cast iron kettle. Made from authentic materials in time-honored designs, they invoke the spirit of friendship through relaxation.

What we really like about this teapot is the quality of the material and craftsmanship.

  • Stovetop Safe: No
  • Made in: China

Affordable Pure Cast Iron Option: Hwagui Japanese Cast Iron Teapot

This well-appointed teapot from Hwagui is a close competitor for best value tetsubin. Similar in style to the Suyika kettle with a black hobnail finish and hemp-wrapped handle, it’s not enameled and thus, stovetop-safe.

Available in sizes from 23 to 41 ounces, it serves from two to four — each comes with a reusable fine mesh infuser.

Hwagui Cast Iron Teapot

  • Stovetop Safe: Yes
  • Made in: China
  • Infuser Included: Yes

There are three minor differences between this kettle and the Suyika, our pick for the best value for money. The lid on the Suyika is recessed — the Hwagui has a small raised edge. Functionally, both lids stay put when you pour, so the design is a matter of preference.

The Suyika’s handle also has a more pronounced curve that makes the pot feel better balanced, but it’s not a deal-breaker. The real contrast is the price — you’ll pay a third less for the comparable Hwagui. If you’re on a budget, it’s the bargain you’ve been waiting for.


  • Excellent value for money
  • Great overall quality
  • Stylish and durable
  • Safe to use on any stovetop

Cast Iron Teapot Buyer’s Guide

A cast-iron tea kettle is an investment. Consider these key points before you buy.

1. Material Quality

Like most materials, cast iron comes in different grades with matching prices. The difference is less in the material than in how it’s forged.

Kettles made in Japan are of the highest caliber, subjected to precision standards and strict quality control measures that result in a smoother, more refined finish. The downside is you’ll pay a premium of 30 percent or more.

Kettles from China are created for the mass market, and so the emphasis is on keeping the price down by taking shortcuts. Products are completely safe and fully functional but the finish is less polished.

The kettle is for both brewing tea and making an attractive addition to your kitchen. Only you can decide where quality and your budget meet.

2. Tetsubin or Tetsu Kyusu?

All Tetsubin are made of cast iron, but not all cast-iron kettles are Tetsubin. Modern versions with a glazed enameled finish are called Tetsu Kyusu.

Tetsu Kyusus are rust-resistant and simpler to clean because they’re enameled, but most should be used only for brewing and not to heat water because high temperatures can crack the finish. Select models are cooktop-safe.

Tetsubin are more versatile and can be used to boil water. The interior finish is rough, but tannins in tea react with the bare cast iron to form a nonstick coating over time that repels rust and adds a subtle dimension of flavor.

Both are fine products as long as you know what you’re getting, but enameled kettles are more popular for their convenience and price — conventional, unglazed tetsubin are crafted of premium cast iron and cost significantly more. Today, Tetsu Kyusu are so ubiquitous they’re referred to as tetsubin because they’re similar in style.

3. Capacity

Cast iron kettles come in sizes from 0.5 to 1.5 liters or more. Choosing the right size is straightforward. First, consider that the tetsubin should only be filled about 70% full when brewing tea. Then multiply the capacity of your cups by the maximum number of people you serve at one time and add a few ounces to cover evaporation loss.

If you’re between sizes, go for the larger size — cast iron retains heat well, and the extra capacity is nice for a quick warm-up.

4. Design

If you’re shopping for a Japanese cast iron kettle, chances are you appreciate Asian tea culture and want to incorporate its design elements into your home. Choose a black hobnail kettle for a modern kitchen or consider a brightly colored teapot with a floral relief pattern for a rustic look.

Tetsubin and Tetsu Kyusu both come in a wide range of styles from traditional to eclectic with lines and colors that fit any décor.

5. Do You Need Just a Pot or a Set?

A cast iron pot can pour tea into any cup. But the oversized coffee mugs most of us have on our shelves are too large for tea.

Experts say 3–5-ounce cups are ideal for coaxing maximum flavor from your brew. If you don’t have the right size, consider buying a full cast iron tea set. Most come with 2–4 matching iron or porcelain teacups.

4 Important Tips for Using and Maintaining Your Cast Iron Teapot

Here are a few important things to remember when using your tetsubin:

First Use: The first time you use the teapot put about 5 grams of tea into the infuser and pour boiling water to fill the pot about 70% full. Let it steep for 10 minutes and then discard the tea. This will remove any cast iron odor and creates a protective layer to prevent the kettle from rusting.

Maintenance: Don’t use any detergent or sponge to clean your teapot. Just remember to empty it after each use and don’t leave moisture inside. Pour any liquid out and remove the lid so the kettle will dry. If you want, you can wipe it both inside and outside with a soft cloth.

Don’t Heat When Empty: Don’t heat an empty cast iron kettle as it might get damaged. Also, don’t put cold water into a hot teapot. Either add a bit of hot water first before putting cold water in or pre-warm the water before pouring it into a hot kettle.

No Microwave or Dishwasher: Tetsubin is the type of teapot you should never put in a microwave or dishwasher.

Japanese Cast Iron Teapot FAQ

Can I heat my cast iron teapot on a stove?

Some cast iron teapots are safe to be heated on a stovetop. Yet, tetsubin are mostly used for brewing tea, not for heating water.

Check the instructions that come with the product to find out if your kettle can be heated on a stove. If you do heat it on a stovetop, use a low temperature setting to avoid damaging the teapot. Also, never heat an empty tetsubin.

Can I use my Japanese cast iron kettle to brew coffee?

We recommend using your tetsubin only for making tea. Using it to brew other beverages such as coffee might leave unpleasant flavors in the pot.

Will a cast iron teapot rust over time?

When you have a high-quality Japanese cast iron teapot, it does not rust easily when maintained well. Don’t leave liquids in the teapot for longer periods of time and let the tetsubin dry properly after each use.

However, over time it is inevitable that some rust will accumulate on the teapot. You can safely remove it by boiling oolong tea or green tea leaves in water and leaving it in the pot for a while. You can also take a soft cloth, wet it with the green tea, and then gently wipe both the interior and exterior of the kettle.

  1. Iron tea kettle without enamel inside is the most traditional and should not be overly cleaned inside as the rust is believed to enhance taste.

  2. FYI, TOWA workshop tea pots are all made in China then finished processed in Japan. I would not trust China cast iron as they have a very long history of using contaminated iron with heavy metals.

  3. Joonas,
    The first picture in the actual article, just under “History of Tetsubin – Japanese Cast Iron Teapot” with two green teacups, is a tetsubin with an orbit design. I would like to purchase one just like the one in that picture. Can you tell me who the manufacturer is and where I can get one exactly in that design. I have been wanting one with an orbit design, which I feel is much more soothing and delightful to look at than those with the traditional hobnail design. Any help you can give me in purchasing one of that same design in the picture would be greatly appreciated.
