KOTAI こたい Philosophy


kotai /こたい (japanese)

  1. 固体 : chem. solid ( adj. solid )
  2. 個体 : philos. individual/ biol. singleton

The name KOTAI describes the concept the products are designed after.

We break down an object to the minimum of what it can be, to make it as solid as possible. In combination with a high quality of material it gives a frame in wich individuality can be unfolded.

The solidity of an object creates a space for individuality to be formed over time

The design language follows characteristics of the Japanese concept of Wabi Sabi, highlighting a sense of melancholy where nothing is finished or perfect.

Wabi Sabi is the Japanese art of finding beauty in imperfection and profundity in nature, of accepting the natural circle of growth, decay and death.

It’s simple, slow and uncluttered.

It celebrates cracks and crevices and all the other marks that time, experiences and loving use leave behind.


origawa / 折り革・おりがわ (japanese)

  1. 折る (oru) : fold

  2. 革 (kawa) : leather

What stands behind the ORIGAWA Collection?
