Kobe is a place where we can develop technical methods and make activities of businesses. In particular, due to near the ocean and the mountain, many amusing foods and culture, and so forth, this place is a favorite.
In Japan, of course, Tokyo is a nice place for everything. However, for startup with technology development, Kyoto or Kobe might be more suitable, in my opinion. However, it takes only about an hour between Kyoto and Kobe.
