Japanese Prime Minister Shizuo Shima expressed caution about the unified 20% separate taxation rule for cryptocurrency in a representative issue at a plenary session of the House of Representatives. "Is it appropriate to encourage investment in cryptocurrency such as stocks and investment trusts that have investor protection regulations? Will the public understand the idea of applying separate self-assessment taxation? There are several issues that need to be resolved. We need to consider it carefully." At the same time, "whether cryptocurrency should be included in ETFs depends on whether cryptocurrency is an asset that needs to be made more easily accessible to the public."
