If Japan is going to be adding 11 more bitcoin exchanges, It is safe to assume that they will be encouraging their citizens to buy more cryptocurrency in the future.
Bitcoin and other cryptocurrencies will be in demand from more people entering the exchanges wanting more coins; and in this case any coin; we may be in for an explosion of buying just from Japan's population. With Bitcoin now looked at as a legal payment currency the demand will increase. If You are looking To invest in Bitcoin look carefully for the buy signs now.
