Quiting the biggest & one of the most crypto-friendly countries makes no sense whatsoever.
Something smells at Kraken.
Consider this.
Binance recently received a warning letter from Japan's financial regulator for operating without license and registration.
Per Reuters:
The regulator said Binance likely allowed Japanese residents to open accounts without confirming their identities, adding that the exchange would face criminal charges if it continued to do business without a license.
That warning was a message to many exchanges, like Kraken, who have been operating outside the law for years in Japan. Jesse Powell is smart enough to know when to cover his ass and bow out of the market.
