As Reuters informed, Oki Matsumoto, a head of online-broker Monex Group Inc is convinced in necessity of regulating Japanese cryptocurrency exchanges according to the same principles as normal banks, because they hold funds of investors.  Matsumoto also noted, that Japanese exchanges perform matching and provide services for storing funds as banks, and it seems like a reasonable for representatives of financial industry if the rules of regulating will become more strict.

Nowadays 32 cryptocurrency exchanges are operating in Japan. Last year the rules were established which oblige trading platforms to separate users funds from assets of exchanges. But this rule has not been converted into effective yet.

As for local online-brokers (Monex, for example), they strictly comply with these rules, and the currency and securities of users are held by independent depositaries, such as trust banks.
