Recently, OSGeo.jp has presented the Japanese translation of the 3rd edition of the GRASS GIS book. It was a pleasant evening in Tokyo with lots of people attending (“Present and Future of GRASS user community in Japan“).
Before reaching the place, we checked in a nearby book store if the book was available: Indeed – found in the book shelf!

A great effort of Tetsuji Uemura to translate 400 pages… the new book is not expensive at all, around 35 Euro. So, please buy it :)
