I really want to know how they manage to control the transactions(taxes purposes).
of course everybody and every country interesting about japan plan to regulate bitcoin,and this will make japan become role model for first country who do that,and i'm corious about that too,i wish its not hard to accept.
It will not be surprise if Japan becomes first country in the world which fully accept Bitcoin as a legal currency.
This is very well developed country, specially in technology and obviously they have good foundation for Bitcoin.
How they will manage to control the transactions (taxes purposes)?
Well, why they should manage control over it?
Main purpose of Bitcoin is anonymity any way.
In many countries there is no tax on capital, only on earnings.
Japan can simple proclaim that there is no tax on Bitcoin but people have to report tax when they exchange Bitcoin to some other, hard currency and cash out on their bank accounts.
