Even though a dining table is an item from a western interior, this table invokes nostalgia in people, the feeling you get when you experience something familiar. It is completely made of cedar(from 75mm thick planks), which comes from Miyazaki Prefecture. For the joint between the table surface board and leg, it uses the ‘Shikuchi’ method of joinery, which is commonly seen in Japanese architecture. ‘Shikuchi’ is a technique that links pillar and girder. The perfect interrelation of angle, surface and pillar makes the interior modern. The table reminds us of a pillar in a house that is present just beside us.

This geometric table with lacquer-coated carving was originally created as a display piece for the Milano Salone. Craftsmen were not used to working on the unusual patterns and size of a table such as this. In general, pictures were on the lacquer coated cravings, not geometrical designs. Some voices even exclaimed, “This project might be better done by machines!”. On the other hand, with a machine, there would be risks of pigments spreading into the grooves of the carving, during the lacquer coating.However, the craftsmen’s pride motivated them to create this table. When the table was completed, it gave a rich impression that could not have been machine-made. ‘It was difficult, though I had this chance to encounter a completely different set of values. This gave me a new idea in spatial craft making”, one craftsman commented with pleasure after completing the table. As a result, this table is a unique fusion of design and craft.A new state appears in which the environment is arranged to make design and craft combine and function together.

The chair on the left shows a carpentry technique of shaving bark, while the chair on the right shows a technique in which leather is attached to a chair.
A wooden chair with a single-leg is unique. The leg is made using a technique in which bark is shaved by turning a piece of wood on a potter’s wheel. Its shape is generated by a rotary motion that looks as if the chair has started rolling,
As for the other chair, its candy-colored leather is modern and elegant. It was designed for an apparel retail store. Thick leather is wrapped around steel bars. The leather wrapping and sewing requires great skill.

Technology in Japan allows for the production of the world’s thinnest gold foil. It is so advanced that gold alloy the size of a ten-yen coin can be stretched to the size of one tatami (traditional Japanese flooring: approximately 1.6562 m2). The technology for creating foil is no longer limited to just gold, but to all kinds of metals, which allows for a wider variety of colors as well. The ring above is made of acrylic fiber, foiled with sterling silver. The integration of the foil’s thinness with the absolute clarity of the acrylic fiber results in a ring that has ice-like characteristics, it being light, airy and translucent. The thinly stretched silver foil gives this ring the appropriate hard texture and feel that sterling silver should have.

We usually think that only cloth or thread can be dyed with plant-derived colors, but this furniture has been given a natural finish with plant-dyes. The way to color bark with plant dyes was very rare in old times. The furniture expresses its natural color. The dyeing color, which is different from the coating color, makes you feel that the wood is breathing.
