OIGEN - Yoi Cast Iron Teapot Set (0.4L) with Trivet – Made in Japan

2026 Summer Limited Edition – "Yoi" Cast Iron Teapot & Trivet Set

The 2026 Summer Limited Edition cast iron teapot and matching trivet set is available in three colors inspired by the beauty of a Japanese summer night: Yoi, Sayo, and Shinyo.

Shinyo refers to the deepest hours of the night, when midnight quietly approaches. Its rich, layered finish evokes a sky filled with countless stars shining against the darkness, capturing the depth and tranquility of a midsummer evening.

This summer, enjoy your cast iron teapot in more ways than one. Beyond brewing tea, it also makes an elegant vessel for serving chilled Japanese sake, bringing a touch of seasonal sophistication to warm summer nights.

With a 0.4L capacity—approximately two go (360–400 ml)—it is perfectly sized for sharing a quiet drink or savoring a few unhurried cups. Whether for tea or sake, the Shinyo set transforms everyday moments into something a little more special.

Notes

• Each piece is individually colored by hand. Due to the handcrafted finishing process and the nature of cast iron, slight variations in color, size, and weight are normal and make every piece unique.
• Depending on the production year or specific model, some authentic OIGEN products may not feature the Nambu Seieido or OIGEN cast mark.
• This teapot is intended for brewing tea only and must not be used to boil water directly. The enamel-coated interior is designed for serving tea and other beverages rather than heating over a flame or stovetop.
