Ichiro's mom and dad run a museum
It is about 140 miles from Tokyo. The Seattle Times ran an article upon the subject, describing all the items inside the museum. It is apparently a documenting of Ichiro's trek through T-Ball to the MLB and presumably will be complete upon Ichiro's retirement from the Mariners.
So when the Press Corps wax journalistic about Ichiro being "used to" his position at the center of mass attention, they are stating the obvious. He has financed it.
When he is home in Japan, he lives in a house behind the museum.
