Looking for MICHIYO KOSUGE (maiden name)

[anwer]

Hi,

I have lost contact with my friend. She is Japanese.
Her maiden name is MICHIYO KOSUGE.
I was in Tokyo in 1979 and she was a doctor at a
hospital:


KUGAYAMA HOSPITAL
2-14-20 Kitakarasuyama Setagaya-ku Tokyo

I believe she has married and the last name might have
changed.
She should be now about 50 years old. The hospital
could not provide me any information. I will be very
thankful for any help in this regards. Is there any doctor's
telephone directory?. Can you please help me in finding
contact information or any advice as how can I search.

Thanks
Anwer
