Ojama, often referred to as オジャマ or お邪魔 in Japanese, are a game play option available in all Pop'n Music games. Ojama are only originally only available in Challenge mode, Super Challenge mode, and NET Taisen, but from Pop'n Music 20 fantasia onwards ojama can be chosen in Normal mode by simultaneously pressing both white buttons.


Ojama are included as an optional mechanic for players wanting more of a challenge. Ojama vary in difficulty, ranging from simple speed-ups to completely overhauling the interface. They reward more points when used however, and these points can be used to unlock items in-game.

Once chosen, ojama are activated during certain sections of songs, indicated by flashing "danger" text in the play area. In the ojama select screen, the white buttons can be pressed to set the ojama to "Throughout" (ずっと), causing it to occur for the whole length of the song instead.


In Pop'n Music, ojama were only available in Hard mode. They couldn't be chosen however, and the ojama used on each stage varied. Rival characters also performed different actions while the ojama was being used as well (Dino breathed fire, Rie-chan made a heart with her hands, etc).

Normal mode featured a variant of the regular ojama, with sections where the background would become flashier and more difficult to see. Unlike Hard mode however, the notes themselves were unaffected by this.

Pop'n Music 2 was the first game to introduce Excite mode, which would later become Challenge mode. Much like the Hard mode of the first game, ojama were always on and varied between stages. Party mode was also added, and it hid various symbols amongst the notes. When the symbols were pressed, they triggered a power-up or an ojama. Pop'n Music 5 was the last game to include Party mode, and Excite mode was renamed to Challenge mode.

Starting in Pop'n Music 6, ojama could be chosen while playing Challenge mode. Up to two different kinds could be selected, and each one gave a set number of points depending on the difficulty. Challenge mode remained this way up until Pop'n Music 19 TUNE STREET.

Pop'n Music 20 fantasia removed Challenge Mode, as such ojama are now selectable in Normal mode by pressing both white buttons. Playing with ojamas activated still gives points, which can unlock several special items and extra stages.

Pop'n Music Lapistoria introduced new options, and as such some ojamas were removed. Ojama points have been changed to "Pop'n Aura", though most point values remained the same.

List of OjamaEdit

Background color and icons indicate difficulty, with light blue being easiest and granting less points, and light pink being the hardest with the most points.
