• Chowa Boxes are handcrafted in Kiri-Bako style, a wooden box making practice with over 300 years of history in Japan. Kiri-Bako (Paulownia box) was developed using leftover materials from Paulownia chests. These boxes have long been used in Japan as a way to store precious items such as ancient ceramic equipments for tea ceremony.


Humidity self-control

Chowa Box seals itself and regulates the humidity inside, making it a perfect container for humidity-sensitive materials.

High heat resistance

Kiri’s high thermal conductivity causes it to carbonize the surface upon ignition, which protects the contents.

Lightweight + Robust

Kiri belongs to the grass family. It has a luxurious appearance and is also extremely lightweight and robust.

Resistant to corrosion

Controlling humidity also results in high resistance to corrosion. The Chowa box maintains durability for decades.

Insect resistance

For hundreds of years, the Chowa Box has been used to store kimonos and silk fabrics, protecting them from insects.

Low shrinkage

Due to its low moisture content, Kiri wood is less prone to shrinking than other woods, and it maintains a consistent structure.
