Do you mind explaining why? Someone showed me a picture of Satoshi Nakamoto written in Hiragana and Katakana and they tried to say that Hal Finney was actually Satoshi through a weird translation that made no sense to me that mixed Hiragana and Katakana into english letters.

I know his name is Japanese... I'll have to read 'The Book of Satoshi' which I have here. The werid thing is every single t-shirt I've ever seen that pays homage to Satoshi Nakamoto has 'Nakamoto' written in Katakana, not Hiragana or Kanji which I thought very strange.
