Size Selection Guide:

• S (35 x 26 cm): Compact — suitable for very small bathrooms, as a secondary mat, or for children. Note: men's feet will extend beyond the mat edges
• M (35 x 45 cm): Standard — suitable for most bathroom layouts as a primary mat for average-sized feet
• L (34 x 59 cm): Recommended — provides full foot coverage for most adults. The size most commonly chosen for daily use

Wellness and Sensory Benefits

• Daily Phytoncide Aromatherapy: Every morning, stepping onto this mat triggers the release of phytoncide — the same natural compounds that make forest bathing (shinrin-yoku) so effective. Documented to reduce cortisol, lower blood pressure, and improve mood. No diffuser, no essential oil, no effort required
• Gentle Foot Massage: The wave-ridged surface provides a subtle, pleasant stimulation to the soles of the feet — a sensory experience that fabric and rubber mats cannot replicate
• Tactile Quality: The warm, smooth texture of natural hinoki against bare feet is incomparably more pleasant than cold rubber or synthetic materials

Functional Benefits

• Natural Mold and Mildew Resistance: Phytoncide and resin compounds actively inhibit bacterial and fungal growth — the mat stays hygienic in the most humid environment in your home without any chemical treatment
• Rapid Drying: The elevated slatted construction drains water immediately and allows air to circulate freely — dries significantly faster than fabric or rubber alternatives
• No Foot Adhesion: The wave-ridged surface prevents the mat from sticking to wet feet — a common complaint with flat wooden mats and fabric alternatives
• Long-Lasting Durability: Properly maintained Shimanto Hinoki bath mats last for many years — far outlasting rubber, synthetic, or bamboo alternatives

Environmental Benefits

• Sustainably sourced from responsibly thinned Kochi forests — buying this mat supports healthy forest management and Shimanto River watershed protection
• Chemical-free production — no toxic runoff, no synthetic materials
• Long product lifespan — fewer replacements, less waste
• Biodegradable at end of life

Key Product Features

• Phytoncide Aromatherapy: Natural volatile organic compounds released when wet — documented stress-reducing, antibacterial, and antifungal properties
• Wave-Ridged Slat Surface: Fine wave-ridge finish prevents foot adhesion, provides gentle massage sensation, and adds natural grip on wet surfaces — no rubber or synthetic coating
• Elevated Quick-Dry Construction: Raised slatted base allows complete water drainage and air circulation for rapid drying after use
• Natural Antibacterial and Antifungal: High phytoncide and resin content actively inhibits mold and mildew without any chemical treatment
• 3 to 6 Month Natural Air Drying: No kilns, no artificial desiccants — slow natural drying preserves essential oils and structural integrity

• Handcrafted by Master Craftsman Ike Ryusho: Decades of Shimanto Hinoki expertise in every mat

Placement

• Place the mat on a flat, stable bathroom floor surface outside the shower or bathtub
• Do not place inside the shower enclosure or submerge in water
• The mat does not have rubber feet — on very smooth, wet tile floors, place a non-slip bath rug beneath if needed
• Size guidance: The S and M sizes are smaller than many customers expect. The L size (34 x 59 cm) is the recommended choice for most adults as a primary bath mat. Please review dimensions carefully before selecting

Daily Use

1. Step onto the mat after bathing — the wave-ridged surface provides comfortable grip for wet feet without sticking
2. After use, prop the mat upright against a wall or lean it at an angle to allow full air circulation on both sides
3. Allow to dry completely before laying flat again
4. Do not leave lying flat on a wet floor — this is the primary cause of premature deterioration in wooden bath mats

Care and Maintenance

• Routine cleaning: Rinse with clean water. No soap required for daily cleaning
• Deeper cleaning: Use a soft brush (tawashi) with clean water to scrub the surface. Rinse thoroughly and dry completely
• Mild soap: A small amount of neutral mild soap may be used if needed. Rinse thoroughly afterward
• Resin spots: Wipe amber-colored resin spots with a cloth dipped in hot water. This is natural phytoncide-rich resin — safe and beneficial
• Do not use bleach, chemical detergents, or abrasive cleaners
• Do not leave in direct sunlight for extended periods — UV exposure causes drying, cracking, and warping
• Do not use in a dishwasher
• Drying after cleaning: Always dry in shade (kage-boshi) — not in direct sunlight. Rapid drying in direct sun can cause cracking

Natural Aging

• Shimanto Hinoki darkens naturally from pale cream to warm honey over time — authentic wood aging, considered beautiful
• The phytoncide fragrance mellows gradually over years of use — it does not disappear, it becomes more subtle
• Occasional light sanding with fine-grain sandpaper (400 grit) can refresh the surface and temporarily revive the fragrance

The Shimanto River: Japan's Last Wild Watershed

The Shimanto River in Kochi Prefecture is one of Japan's last major undammed rivers — a waterway that has flowed clean and uninterrupted through ancient cypress forests for thousands of years. The purity of this watershed, combined with Kochi's warm, humid climate and mineral-rich mountain soil, creates growing conditions that produce Shimanto Hinoki of exceptional density, oil content, and fragrance. This is not ordinary hinoki. It is the most resin-rich, most aromatic, most therapeutically potent variety of Japanese cypress available — and it grows only here.

Tosaryu and Master Craftsman Ike Ryusho

Tosaryu was founded in 1970 in the mountains of Kochi Prefecture by craftsmen who understood that the Shimanto forest was not simply a resource to be harvested — it was a living system to be stewarded. The company's production philosophy has remained unchanged for over fifty years: use only sustainably thinned timber, dry every piece naturally for 3 to 6 months, apply no artificial coatings or chemical treatments, and reuse every scrap of wood that the production process generates.

The Aroma Bath Mat is the work of master craftsman Ike Ryusho, whose decades of experience working with Shimanto Hinoki are expressed in every detail of the mat's design. The wave-ridge surface finish — which prevents the mat from sticking to wet feet while providing gentle grip — was developed through years of refinement to achieve the precise balance of comfort, safety, and aesthetic quality that defines a Tosaryu product.

The Phytoncide Effect

Phytoncide is the collective term for the volatile organic compounds released by trees as a natural defense mechanism. In hinoki cypress, these compounds include alpha-pinene, beta-pinene, and hinokitiol — substances that have been extensively studied in Japanese forest medicine research. The findings are consistent: exposure to phytoncide reduces cortisol levels, lowers blood pressure, increases natural killer cell activity, and produces measurable improvements in mood and sleep quality.

This is the science behind the sensation that every visitor to a Japanese onsen or hinoki bath experiences — the feeling of calm that descends the moment the wood gets wet and the fragrance rises. Tosaryu's Aroma Bath Mat delivers that effect in your own bathroom, every morning, for years.

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

Key Natural Properties

• Phytoncide Content: Shimanto Hinoki contains high concentrations of phytoncide — natural volatile organic compounds including alpha-pinene, beta-pinene, and hinokitiol. These compounds have documented antibacterial, antifungal, and stress-reducing properties
• High Resin and Oil Content: Shimanto Hinoki contains more natural resin and essential oil than standard hinoki varieties — the result of the specific growing conditions of the Shimanto River basin. This high oil content is responsible for the mat's superior water-repelling and quick-drying performance
• Natural Antibacterial and Antifungal: The phytoncide and resin compounds actively inhibit bacterial and fungal growth on the mat surface — no chemical treatment required
• Therapeutic Fragrance: The citrus-pine aroma released when the wood is warm and damp is the natural phytoncide fragrance — strongest when new, mellowing gracefully over years of use

Construction

• Wave-ridged surface finish on each slat — prevents foot adhesion, provides gentle massage sensation, and adds natural grip on wet surfaces
• Elevated slatted base — raises the mat off the floor for complete water drainage and air circulation
• Traditional Japanese woodworking joinery — no metal hardware, no adhesives
• Entirely natural, chemical-free product from raw material to finished mat
• Load capacity: up to 113 kg (250 lbs)

Natural Resin Note

High-quality, oil-rich Shimanto Hinoki may occasionally show amber-colored sticky resin spots on the surface. This is a sign of authentic, premium wood with high phytoncide content — not a defect. It can be wiped away with a cloth dipped in hot water if desired.

About Tosaryu (土佐龍)

Tosaryu was founded in 1970 in the mountains of Kochi Prefecture, Shikoku Island — one of Japan's most forested and least industrialized regions. The company's name combines "Tosa" (the historical name for Kochi) with "ryu" (dragon, suggesting strength and living tradition), reflecting its deep roots in the land and craft of Kochi Prefecture.

For over fifty years, Tosaryu has worked exclusively with Shimanto Hinoki — Japanese cypress sourced from the Shimanto River basin, a watershed celebrated for producing some of Japan's finest and most oil-rich timber. The company's production philosophy has remained unchanged since its founding: use only sustainably thinned timber, dry every piece naturally for 3 to 6 months, apply no artificial coatings or chemical treatments, and reuse every scrap of wood that the production process generates.

Master Craftsman Ike Ryusho

The Tosaryu Aroma Bath Mat is the work of master craftsman Ike Ryusho, whose decades of experience working with Shimanto Hinoki are expressed in every detail of the mat's design. The wave-ridged surface finish — which prevents foot adhesion, provides gentle grip, and creates a massage sensation — was developed through years of refinement to achieve the precise balance of comfort, safety, and aesthetic quality that defines a Tosaryu product. Ike Ryusho's approach to woodworking reflects the Japanese craft philosophy of monozukuri — the art of making things with care, precision, and deep respect for the material.

Sustainability as Operational Reality

Tosaryu's sustainability credentials are not marketing language. The company has been practicing responsible forest thinning in Kochi Prefecture since 1970 — not because it became fashionable, but because the company's survival depends on the health of the forest it works in. Lumber scraps and offcuts are reused in other products. CO2 emissions are actively minimized. The Shimanto River stays clean. This is fifty years of operational reality from a company that lives in the forest it manages.

International Reach

Tosaryu's products are sold across Japan through curated lifestyle retailers and directly through the company's own channels. Internationally, Tosaryu collaborates with BEE HOUSE, a Japanese concept store in San Francisco, bringing authentic Shimanto Hinoki products to the US market.
