I like to keep quiet in threads like these and just watch the carnage from the sidelines, but Chinorlz makes a good point that you ignored. Swedish and Japanese have almost nothing in common as far as languages go. As far as orthography, Swedish uses the Latin alphabet, but Japanese does not. So unless you taught Minase English or you two had correspondence so close that he copies your writing, it's very unlikely that you could make the same spelling errors.
I've been silently rooting for you the whole time because you've been a member here for years and it sucks to have your name dragged through the mud for something you didn't do. But this point doesn't look good for you. I still want to believe you because you seem genuine despite some strange inconsistencies in your story, but then again it's not my money on the line.
