* Editor's Note : This blog post is being prepared to celebrate the research work of our fellow QOTO.org user Chikara, @chikara , who has been sharing the fruits of his curiosity and study of the evolution of Technology, Arts and Science in Japan.

I had meant to suggest to him that his posts would look wonderful in a Blog format, and be preserved, made easier to find for anyone interested in following them.

Upon seeing his post of the Prussian Blue history, and the beautiful gravure of the Great Wave, I knew the moment was now.

Thank you, Chikara, for sharing with us all of your findings.

チカラ、私たちとあなたの調査結果のすべてを共有していただきありがとうございます。
