Bishop's e-mail address

I wish to send a mail to the bishop, Could you please tell me his e-mail address? I’m sorry not to be able to write in Japanese with this PC. I’m a priest of the Prelature Opus Dei. I lived in Japan for 48 years. I published a book in Seibo Bunko “Shinpusama, natto suki desuka”. I came back to Spain in 2005. I see regularly Katsuya Sonoda. He told me about the bishop´s blog, and also that he is coming to Pamplona in August. I met Most Rev. Koriyama some 30 years ago in Ashiya City.
