What Japanese title did the Nintendo DS game Rhythm Heaven use?

The Nintendo DS game Rhythm Heaven was titled Rhythm Tengoku Gold in Japan. Its Japanese title is commonly rendered in English as Rhythm Tengoku Gold, distinguishing it from the Western name Rhythm Heaven.

The game launched in Japan on July 31, 2008, following the Japan-only Game Boy Advance original, Rhythm Tengoku. It became the first entry in the series to receive releases outside Japan: Rhythm Heaven in North America and other regions, and Rhythm Paradise in PAL territories.

The word “Gold” can cause confusion because the series has several similarly named Japanese releases. Rhythm Tengoku: The Best+ is the Japanese title of Rhythm Heaven Megamix, while Minna No Rhythm Tengoku is the Japanese title of Rhythm Heaven Fever, the Wii sequel.
