Yup, it's just normal. KYC and AML are clearly necessary nowadays when transferring values from crypto world to fiat world.

Improvement. Nothing scary

To be honest, Japan has always come across as a crypto-friendly country despite huge turbulence caused by incidents like the Mt. Gox hack. Japanese people are very lucky because of this! The exchanges should respect the requests of the regulator and stay compliant. I wished more countries were like Japan!
Yeah at the very least their government or government agency are regulating the use of crypto exchanges in Japan and their are not opposed to it, unlike some countries where they are banning crypto exchanges. Also it is for the protection of the users of such exchanges and I think Japan will soon legalize of cryptocurrency in their country.
