Andres Laszlo Sr.'s Mi Uncle Jacinto was published in Japanese and the publishing rights have reverted to me. However, I have not managed to find out whether the translation rights are mine or not, nor do I know how to republish text in Japanese.
However, I have scanned the original text and I am presently wrestling with the issue of subjecting it to OCR and having it edited. If you have any interest in a Japanese edition/translation of any of my or my father's books, please do not hesitate to contact me.
