Material of Tatami

Design Your Perfect Space with Custom-Made Tatami

The Three-Layer Structure of Tatami — A Fusion of Tradition and Function A tatami mat consists of three main components. By customizing these layers, you can create the perfect mat tailored to your needs.

Internal (Tatami-Doko / Core) The foundation that provides the mat's structure. Options range from traditional rice straw to modern materials like wood fiberboard, insulation foam, or high-performance "Zetron." The core determines the cushioning, weight, and thermal insulation.
Surface (Tatami-Omote) This is the visible layer that comes into direct contact with your skin. Whether made from natural rush grass, Japanese paper, or resin, this "face of the tatami" defines the aroma, durability, and visual aesthetic of your room.
Border (Tatami-Heri) The fabric edges that protect the corners and reinforce the mat. With hundreds of colors and patterns to choose from, the border acts as a frame, allowing you to switch between a classic Japanese look and a sleek, modern design.

Natural Japanese Rush Grass

The Power of Natural Japanese Rush Grass — Traditional Comfort for Modern Living

Grown in the rich soil of Japan, natural rush grass (Igusa) offers remarkable benefits that enhance both the beauty and the health of your home.

Soothing Aroma (Forest Bathing Effect): The natural fragrance contains "vanillin," which provides a relaxing effect similar to a walk in the forest.
Moisture Regulation: It acts as a natural humidifier, absorbing moisture during humid summers and releasing it during dry winters for year-round comfort.

Combining traditional craftsmanship with modern design, we bring the serenity of Japanese.

Tatami-Heri (Borders) — The Artistic and Functional Frame

"Tatami-Heri" are the fabric borders sewn onto the long sides of tatami mats. They are not merely decorative but are essential components that define the durability and aesthetic of the room.

1. Key Roles and Utility

Edge Protection: They reinforce the corners and edges of the mats, preventing the woven rush from fraying and ensuring long-lasting use.

Closing Gaps: The borders help fill minor gaps between mats when laid out, creating a seamless and stable floor surface.

Visual Identity: The border acts as a frame for the room. With hundreds of colors and patterns available, they can transform a space from a traditional sanctuary to a modern interior.

2. Types of Materials

Synthetic Fibers (Polyester/Polypropylene): The most common today. They are highly durable, resistant to friction, and available in an endless variety of colors that do not fade easily.
