The title uses all caps in Japanese.

"P", "L", "U", "T" & "O" are Japanese character letters? Are you serious?

The title doesn't need to use Japanese characters, it just needs to be the first title used for the original Japanese release. Right now, the press release (linked in my initial reply), the Japanese Netflix website, and the anime's official website all use "PLUTO" as the Japanese title so the Original Title should be "PLUTO."

If the casing of the letters is changed or if the title is changed to use Japanese characters instead, the Original Title should and will be updated on TMDB.

All these years you don't simply understand that Japanese people are using only capitals in their titles because the Japanese language DOES NOT HAVE CAPITAL LETTERS and they express Latin (English) Alphabet that they use (it's not theirs to even try making their own rules) in capital letters too! That doesn't mean they always "shouting" in Japanese & English language with their titles. They just attempt, in writing, to ADJUST their letters to Latin Alphabet. The English Language, however, has its own rules. This is common sense of understanding Japanese and their writings and only foolish people that cannot comprehend that so many years, always resort to images of typed titles in Japanese websites attempting to give "an example of the proper". You have sometime to realize that you' re doing damage to this database keeping that attitude in titles providing false and misleading information. I'm not talking to you specifically of course but to anyone who is keeping that line and be in some power position.
