Onsen Nozokimi Daisakusen

The game took inspiration from how the player visits a bath in Persona 4, but the scenario is otherwise not connected to Persona 4. The game was popular but saw mixed reception: some were baffled by the concept and the game's existence, while some enjoyed it.

• Illustration — The player clicks to the beat of the music to fill up the heart gauge. Onsen Nozokimi Daisakusen is a rhythm minigame in which the player, located on the men's side of an open-air onsen hot-spring bath, tries to look into the women's side through a hole in the middle partition to spy on the Persona 4 character Chie Satonaka while she is bathing, while avoiding getting caught. To do so, the player must repeatedly click with the mouse on the hole to the beat of the music, in double time, to fill up a heart gauge. They have to avoid clicking too rapidly, which results in Chie noticing them, calling them a pervert, and beating them up; if they on the other hand click too slowly, the fifteen-second timer runs out, and they lose their chance to look any further. Completing the game lets the player see Chie bathing and gives them the option to play a second challenge where they get to see her bathing together with Yukiko Amagi, another Persona 4 character.

Onsen Nozokimi Daisakusen was developed in Adobe Flash, and took inspiration from a sequence where the player visits a bath in Persona 4, although the scenario is otherwise not connected to Persona 4 plot. Siliconera described it as part of a trend of Japanese video games having Flash-based demos, while noting that Onsen Nozokimi Daisakusen does not actually act as a demo for Persona 4. The game was published by Atlus on July 2, 2008, as a browser game playable on the official Japanese Persona 4 website, released as part of a promotion for the Japanese release of Persona 4 the following week, together with wallpapers and new trailers. In 2015, Atlus released Hanate Wotagei! Rise no Dance Battle, another browser game with similar clicking gameplay but different theming, to promote their rhythm game Persona 4: Dancing All Night.
