There are many things that make being a technology entrepreneur in Japan challenging and not all of these challenges are unique to Japan, but they are absent from the USA. So when we look at the innovation coming out of the USA I think its important to keep these things in mind.
The first is the lack of new startups. In Japan there has been a lot of activity around incubators in an effort to encourage new startup activity and I think the effort is admirable but flawed. Its flawed because the hiring system in Japan is completely structured around new graduates. The brightest new graduates are eagerly recruited by Japan’s top government or business organizations in what is meant to be a long career track to top management.
