Yes i also think that Japan is a huge market for crypto currencies and blockchain project, if ehealth can developp some partnerships in Japan I think it can be very good. The roadmap of the project is long, so there is still time to think about it.
Japan is an ideal place for ehealth and I hope they will make a lot of partnership in this country. Some good ideas related health come from Japan which is good for the project.
Crypto is fine in Japan, but what about the Heath Standards? Is it link in other countries or very special?
