Tokyo, July 9, 1962
Dear Professor Lederberg,
I heard from Dr. Kageyama that he will be accepted in your laboratory from Sep. 1963.  He will be quite happy to work under your guidance from 1963.  I am very glad too to keep him one year more in my laboratory.
Now I am planning to visit your country next May.  I shall be very glad to see you in your laboratory.
My best regards to Mrs. Lederberg,
Yours sincerely,
F. Egami
