Masu WallJapanese hinoki masu modules for architects and interior designers.

The traditional 1-go masu, made of Japanese hinoki and supplied as a wall module. You design the wall; we make the modules in Japan and ship them to your project — a warm, precise surface for Japanese, Japandi and wa-inspired interiors.

Philosophy

We do not impose a finished design. We provide the essential material.

FOMUS ARCHITECTURAL is a product line that reimagines Japan’s culture of materials as a way of thinking for architecture. What we offer is the essential material for making a space. How it is used is decided by the designer — and by the space itself.

Material

Hinoki grown in Japan, carefully selected for quality, fragrance and density. Its quiet presence, the warmth you feel at a touch, and a character that deepens with time.

The Masu

An object whose name means “to prosper.”

The masu (枡) is a square box of hinoki cypress. For more than 1,300 years it was used in Japan to measure rice and sake. Its name sounds like masu (増す) — “to increase, to prosper” — so it became an auspicious object, used at celebrations and given as a gift of good fortune.

Masu Wall turns hundreds of these boxes into one surface: warm hinoki, a precise grid and a quiet play of light and shadow. It brings the restraint of Japanese interior design — the calm of wabi, the honesty of natural wood — into hotels, restaurants and homes, with a meaning of welcome and prosperity built in.

Where It Works

A hinoki wall for Japanese and Japandi interiors

Masu Wall is a material for any space that wants the warmth of Japanese wood and a clear, modular rhythm. The modules can be used for walls, partitions, columns and fixtures — as you design them.

Wall

A surface that softens light and shadow and holds the eye.

Partition

Screens the view while letting air pass through — dividing a space without closing it.

Column & Fixtures

Columns and fixtures become a quiet focal point of the space.

How It Works

You design the wall. We supply the masu.

Masu Wall is sold as modules. Architects, designers and owners work with the masu like any other material, and FOMUS delivers them from Japan.

  1. STEP 01

    Design your wall

    You or your architect / interior designer design the pattern, layout and backing to suit the space. If you would like, FOMUS can prepare a design proposal (optional, charged separately).

  2. STEP 02

    Choose quantity & specs

    Decide the number of masu and the specification: individual modules or panel type, glass coating, fire-retardant treatment, engraving.

  3. STEP 03

    Made in Japan

    The masu modules are made at a workshop in Japan in Japanese hinoki, individually or pre-assembled as panels.

  4. STEP 04

    Shipped by FOMUS

    FOMUS arranges shipping from Japan to your country.

  5. STEP 05

    Installed by your contractor

    Your local contractor installs the wall. FOMUS provides installation instructions, and can also work with your local contractor.
