I don't remember having seen wood toys prettier than those by take-g toys. Takeji Nakagawa, aka Take-G, creates adorable toys and crafts, like the wonderful wood robots. The robots and his other crafts are actually art works, sold only at exhibitions and art galleries. About his work:

Yosegi-Mokuzougan, or joined wooden block construction, is craft skills where combinations of original and unique colors and textures of different kinds of wood are utilized to express artistic patterns. In Japan, the Hakone-Odawara region is famous for this traditional handicraft. Products of the Take-g Toy’s have expanded this traditional craft skill, which usually employs two-dimensional patterns, by using three-dimentional patterns, instead. We use four different kinds of wood, a keyaki (a Japanese tree of the genus Zelkova), a teak, a walnut, and a white ash.

Arata Sasaki interviewed Takeji Nakagawa for Hitspaper. The interview is available in Japanese and English.
