Prefatory Note
Tsuyoshi Sakurai
Our Sakurai seminar decided to drop the fourth graduation this time. I am really grad that our seminarists of this year planned to publish the seminar ‘s journal at the opportunity of graduation. This is of course for me, but it must be a good memento to the members of the seminar.
The journal will be titled “Dialogue”. It must be said that it is truly worthy as the title of the seminar’s journal.
