What Korean name had earlier Rhythm Heaven games used due to trademark issues?

The Korean name used by earlier Rhythm Heaven games was Rhythm Sesang. The Korean title, 리듬 세상, translates roughly as “Rhythm World,” distinguishing the series from the more literal Rhythm Heaven name.

Nintendo used Rhythm Sesang for several Korean releases, including the Nintendo DS game, the Wii entry, and Rhythm Heaven Megamix on Nintendo 3DS. The naming change was connected to trademark complications surrounding the Korean wording for “heaven.”

This can be confusing because Rhythm Tengoku is the original Japanese title, while Rhythm Paradise is the name used in PAL territories such as Europe and Australia. Neither is the Korean title. The Korean localization later changed direction: Rhythm Heaven Groove was announced under the Korean name Rhythm Cheonguk, the direct Korean equivalent of “Rhythm Heaven.”

That change makes Rhythm Sesang an important marker in the series’ localization history. It identifies the earlier Korean naming era, while Rhythm Cheonguk identifies the newer branding used for Groove.
