AI Japanese Song Generator

Japanese popular music covers ground that rarely overlaps: city pop's smooth, funk-inflected 1980s sound has found a second life with a global streaming audience; anime theme songs (anisong) drive some of the biggest chart moments in the country; J-pop covers everything from idol-group pop to rock-leaning bands; and vocaloid culture built an entire scene around synthetic, deliberately un-human vocal delivery.

Autunes generates full Japanese songs from a text prompt or your own lyrics — melody, vocals, instrumentation and mix together — across city pop, anisong-style tracks, J-pop, vocaloid-style pop and Japanese rock. Write the prompt in Japanese or English.

City pop wants a funky bassline, glossy electric piano and a smooth, laid-back vocal delivery reminiscent of late-night drives. An anisong-style track needs high energy, a big hook built for an opening or ending sequence, and a vocal with clear emotional drive. J-pop covers wide ground, so naming whether you want idol-group brightness, rock-band energy or ballad restraint matters. Vocaloid-style prompts should call out the deliberately synthetic, rapid-fire vocal character the scene is known for.

Keep lyric lines short and rhythmically simple when pasting your own Japanese text; the model fits syllables to melody, and dense lines can crowd the phrasing. Mixing kanji, hiragana and katakana is fine, but keep spelling consistent for names or repeated words. Name the decade or scene you are referencing, such as '80s city pop' or '2020s anisong,' to steer the production style more precisely than genre alone.
