Why is Coinbase shutting down in Japan?

Could you possibly explain the reason behind Coinbase's decision to close its operations in Japan? It seems like a rather unexpected move, given the significant presence and influence of cryptocurrencies in that region. Is there a specific regulatory issue or market condition that's driving this closure? I'm curious to know if this is a temporary measure or a permanent exit from the Japanese market. Furthermore, what does this mean for the cryptocurrency community in Japan? Will they still be able to access Coinbase's services, or will they need to seek alternatives? It would be helpful to have some clarity on these points.
