This could be an extremely interesting development. As I read it, Japan want to introduce rules making individuals manage their own digital assets (i.e. cant be left on the exchange)
The keys lines are:
"…the upcoming G20 Summit in Osaka, Japan, from June 28th to 29th, lists cryptocurrencies as a leading topic on the agenda. Prime Minister Shinzō Abe’s government will address recent amendments to the Financial Instruments and Exchange Law and the Fund Settlement Act regarding virtual currencies and the digital economy.
There will be a special focus on security. In the wake of the Coincheck hack, which drained $532 million worth of NEM last year from the Japanese crypto exchange, policymakers are aiming to intensify crypto trading restrictions.
Following the coincheck hack, which was made possible due to crypto storage in hot wallets that interfaced with the internet, Japan’s Financial Services Agency has introduced legislation that requires customers to manage their own crypto assets using a “cold wallet” that is disconnected from the Internet."
