Trying to decide as well as determine the cost to take up a invitation from one of my former students, who now lives in Japan and studies under a student-teacher of Masaaki Hatsumi

In other words, my student is so excited about his new study, that he was granted permission to invite a guest (myself) at a upcoming ceremony-of sort honoring Masaaki Hatsumi.

Shall I go and meet Masaaki Hatsumi?

How much would a round trip flight and/or expenses be out of the U.S.?
