Daily Use

1. Place the mat on a flat, stable bathroom floor surface beside the bathtub or shower
2. Step onto the mat after bathing — the ridged surface provides comfortable grip for wet feet
3. After use, stand the mat upright against a wall or prop it at an angle to allow full air circulation on all sides. This is the single most important step for maintaining the mat's longevity
4. Allow to dry completely before laying flat again

Care and Maintenance

• Daily: After use, stand upright or prop at an angle for full air drying. Do not leave lying flat on a wet floor
• Weekly: Rinse with clean water and allow to dry thoroughly. No soap or detergent required for routine cleaning
• As needed: For deeper cleaning, use a soft brush with clean water only. Rinse thoroughly and dry completely
• Resin spots: If natural resin appears on the surface, wipe gently with a cloth dipped in hot water. This is a sign of high-quality, oil-rich wood and is completely safe
• Do not use bleach, chemical detergents, or abrasive cleaners — these strip the wood's natural oils and eliminate the hinoki fragrance permanently
• Do not leave in direct sunlight for extended periods — UV exposure can cause the wood to dry out, crack, or warp
• Do not soak in water or leave submerged
• Do not use in a dishwasher

Natural Aging

• Shimanto Hinoki will naturally darken from pale cream to a warm honey tone over time with regular use — this is the natural aging of authentic wood and is considered beautiful
• The hinoki fragrance is strongest when new and mellows gradually over years of use — it does not disappear, it simply becomes more subtle
• Occasional light sanding with fine-grain sandpaper (400 grit or finer) can refresh the surface appearance and temporarily revive the hinoki fragrance
• With proper care, this bath mat will last for many years — far outlasting any synthetic or rubber alternative

Kochi Prefecture: Where Japan's Finest Hinoki Grows

Kochi Prefecture occupies the southern face of Shikoku Island, where the Shimanto River — one of Japan's last major undammed rivers — flows clean and cold through ancient cedar and cypress forests. The purity of this watershed, combined with Kochi's warm, humid climate and mineral-rich mountain soil, creates growing conditions that produce hinoki cypress of exceptional quality. The Shimanto Hinoki that grows here is denser, more oil-rich, and more fragrant than hinoki from other regions — qualities that have made it prized by Japanese craftsmen for generations.

It is from these forests that every Tosaryu bath mat begins.

Tosaryu: Five Decades of Sustainable Woodcraft

Founded in 1970 in the mountains of Kochi Prefecture, Tosaryu has spent over fifty years developing a woodworking practice that is inseparable from its commitment to the forest. The company's name reflects its roots — "Tosa" is the historical name for Kochi Prefecture, and "ryu" suggests a flowing, living tradition.

Tosaryu's approach to production is built on a principle that is increasingly rare in modern manufacturing: patience. Where industrial wood processing uses artificial desiccants and chemical treatments to accelerate drying, Tosaryu dries every piece of Shimanto Hinoki naturally for 3 to 6 months. This slow, unhurried process allows the wood to release moisture gradually without stress, preserving the cellular structure that holds the essential oils responsible for hinoki's antibacterial properties and therapeutic fragrance. The result is wood that performs better, lasts longer, and smells exactly as nature intended.

Responsible Thinning: The Forest as a Living System

Tosaryu's sustainability practice goes beyond simply using natural materials. The company actively participates in the responsible thinning of Kochi's forests — a practice that removes overcrowded trees to allow the remaining trees to grow stronger and healthier. This thinning is essential for maintaining the biodiversity of the forest, keeping the Shimanto River clean, and ensuring that future generations of craftsmen have access to the same quality of wood that Tosaryu uses today.

Lumber scraps and offcuts from production are reused in other products rather than discarded, and the company actively works to minimize CO2 emissions throughout its operations. This is not a marketing claim — it is the operational reality of a company that has been doing business in the same forest for over fifty years and understands that its future depends on the health of that forest.

Primary Material

• Shimanto Hinoki (四万十ひのき): Japanese cypress (Chamaecyparis obtusa) sourced exclusively from the Shimanto River basin, Kochi Prefecture, Japan
• Grade: Natural shiraki (unfinished white wood) — no coating, lacquer, varnish, stain, or chemical treatment of any kind
• Drying Method: Natural air drying for 3 to 6 months — no artificial desiccants, no kiln acceleration, no chemical treatments

Natural Properties of Shimanto Hinoki

• High Oil Content: Shimanto Hinoki contains an exceptionally high concentration of natural resin and essential oils compared to standard hinoki varieties — the result of the specific growing conditions of the Shimanto River basin
• Hinokitiol and Alpha-Pinene: The essential oils in hinoki include hinokitiol and alpha-pinene, natural compounds with documented antibacterial and antifungal properties — making this bath mat inherently resistant to mold and mildew in wet bathroom environments
• Therapeutic Fragrance: The terpene compounds in Shimanto Hinoki produce a distinctive clean, citrus-like, forest aroma that is released when the wood is warm and damp. This fragrance is most pronounced when new and mellows gracefully over years of use
• Natural Resin Spots: High-quality, oil-rich hinoki may occasionally show sticky resin spots on the surface. This is a sign of authentic, premium wood — not a defect. It can be wiped away with a hot damp cloth if desired

About Tosaryu

Tosaryu was founded in 1970 in the mountains of Kochi Prefecture, on the island of Shikoku — one of Japan's most forested and least industrialized regions. The company takes its name from Tosa, the historical name for Kochi, and has spent over fifty years developing a woodworking practice that is defined by two inseparable commitments: exceptional craft quality and genuine environmental responsibility.

Tosaryu works exclusively with Shimanto Hinoki — Japanese cypress sourced from the Shimanto River basin, a watershed celebrated for producing some of Japan's finest timber. The Shimanto River is one of Japan's last major undammed rivers, and its health is directly connected to the health of the forests that Tosaryu manages. This is not a coincidence. Tosaryu's responsible thinning practices actively maintain the biodiversity and water quality of the Shimanto watershed, creating a direct link between the company's commercial activity and the ecological health of the region.

The Patience Principle

What distinguishes Tosaryu from other woodworking companies is its refusal to accelerate the production process at the expense of quality. Every piece of Shimanto Hinoki is air-dried naturally for 3 to 6 months — a timeline that is commercially inconvenient but technically essential. This slow drying preserves the wood's essential oils, maintains its cellular structure, and ensures that the finished product performs as the material was designed by nature to perform: antibacterial, fragrant, moisture-resistant, and durable.

Zero Waste, Reduced Emissions

Tosaryu reuses lumber scraps and offcuts from production in other products, minimizing waste at every stage of the manufacturing process. The company actively works to reduce CO2 emissions throughout its operations — a commitment that reflects the understanding that a woodworking company's long-term viability is inseparable from the long-term health of the forests it depends on.

Tosaryu makes a range of functional household products from Shimanto Hinoki, including bath mats, bath stools, cutting boards, and kitchen accessories. Every product shares the same material philosophy: pure, natural, chemical-free, and made with the patience that genuine quality requires.
