Also were there differences when it came to Americans of distinguished class like the family of the US Ambassador versus an ordinary sailor? Were US students allowed to attend the University of Tokyo? Was there discrimination against fellow Japanese who associated with Americans?
Were US students allowed to attend the University of Tokyo?
I don't know if they were allowed earlier, but the first non-Japanese American to graduate from the University of Tokyo was Don Cyril Gorham, who graduated in March 1941. So if there were any American students in the Taisho period, they didn't graduate at least.
