KOUHIN

KOUHIN is the tatami brand of Hirohama Co., Ltd., headquartered in Kita-Hiroshima, Hiroshima, with additional operations in Hiroshima City. Since its start in 1916, the company has grown from factory-based tatami craftsmanship and continues to support tatami-centered living today.

Tatami surfaces are offered across multiple material types. Domestic igusa surfaces use igusa from Yatsushiro, Kumamoto, and the brand explains approaches that make the most of igusa's comfort. Japanese paper surfaces focus on durability, resistance to fading, and water repellency for daily life.

The lineup includes made-to-order tatami, lay-on tatami for flooring, tatami beds, and tatami seating and modular units. Color and pattern variations are also prepared, helping you choose by room mood as well as by function.

KOUHIN manufactures tatami in-house while checking materials, and re-covering is described as a long-term maintenance option. After consultation, an estimate is guided within about three days. Multiple online channels are also available, including a Rakuten store.

Established from a tatami-making legacy since 1916

KOUHIN traces its roots back to 1916 and later incorporated in 1959. The brand continues to expand tatami options that fit today's homes and lifestyles.

Choose the surface: igusa, Japanese paper, or resin

Options include domestic igusa (using igusa from Yatsushiro, Kumamoto), durable Japanese paper surfaces designed for everyday use, and resin surfaces that handle water and dirt more easily.

Washable tatami is part of the lineup

A resin pipe-like structure helps reduce fuzzing and supports long-term comfort. The brand also notes water-wash and detergent use, plus easy wipe-clean maintenance.

In-house production and re-covering support

Tatami are produced in-house with material checks. When surfaces wear over time, re-covering is presented as an option, and estimates are guided with a "within 3 days" target after consultation.
