Joe shared a Japanese-language link with us about this news. Here’s an English article.

As I wrote in response to Joe’s post, lack of a unified approach to bus service has been an interest of mine for a number of years. In particular, I’ve been hoping that it would become possible to use Google maps to figure out how to get around town by bus. This can be done in most cities around the world but not in Kumamoto. I hope this joint venture fixes this problem.
