Thank you so much Frank, i really appreciate your suggestion. I dont know if she's married or not, we lost contact for about 10 years. and i dont know where she lives now, maybe in Tokyo or could be back to Hiroshima. I dont know her maiden name, i just called her by Tomoyo on the letters. Tomoyo Kubota is her proper name. I have some pictures of her but i dont know if it will help. Im thinking about Gakushuin university alumni list, but i cant find it on the net. I believe her data should be available in Gakushuin university's data base. But then if i call the university i dont think they will answer such a question.
