Kraken - according to coinmarketcap.com, the 12th largest exchange for cryptocurrencies - withdraws from Japan.
This is surprising since Japan is presumably one of the countries with the largest volume of cryptocurrency trading. The most recent statements issued by the National Bank of Japan on the subject of cryptocurrencies also gave rise to the hope that the market could and would continue to grow.

The reason for Kraken to withdraw nevertheless, is probably that the operating costs in Japan make a continuation of the operation at the current time unprofitable. A resumption of operation in Japan for the future should not be expressly excluded.
Eventually the operating costs of the new licensing process in Japan have increased so much that this step has now taken place. A return to Japan will seem to be closely linked to whether and how it will be possible in the future to fulfill the legal framework while pursuing profitable business.
Until recently.
