As confirmed by MyAnimeList, One Piece is still known as One Piece in Japanese.

While you've provided plenty of examples of anime whose English names are translated from the original Japanese, One Piece is not the only anime whose Japanese name is in English. Black Lagoon, Angel Beats, Death Note, and Summer Wars are other prominent examples.

    This is really simple and makes sense. Thanks. May 16, 2022 at 17:29
  • The One Piece Wiki has some more details on the name and translation too: "In the original manga, the term "One Piece" (ワンピース Wan Pīsu?) is often accompanied by an additional string of text translating roughly to "the great hito-tsunagi treasure" (ひとつなぎの大秘宝 Hito-tsunagi no Dai-hihō?), initially as a separate descriptor[7] and later as a base-text directly glossed with the "One Piece" katakana." onepiece.fandom.com/wiki/One_Piece
