Masataka Morimoto
From Fujisawa, Kanagawa.
Probably now around 42 yo
2 younger sisters.
I met him in London, ca. 1980/81.
I now live in Japan and I met him a few times around 1994/96, then I lost contact.
At that time his parents were considering divorce, and he was going to stay with his mother. He was also struggling with work, teaching English to kids for a living.
If you find him, please let me know.
Regards,
Carlo
