Ippei Mizuhara served as exclusive interpreter for Major League Baseball player Shohei Otani of the Dodgers. American media outlets are reporting doubts about large sums of money being transferred that Otani claims to have been unaware of.

American bank officials expressed the view that it is possible for a third party to transfer large amounts of money without the person's knowledge. In the United States, you can send money online from your account to another account, but there is no limit to the amount that can be sent at one time.
