Aqua Plus (Aquaplus) is a Japanese publisher and developer responsible for releasing titles such as Comic Party (2001) and Tenerezza (2003). The company is also associated with publishing and distributing various budget titles in Japan, including games from the Simple 1500 Series Vol. franchise such as Roller Coaster World, Xtreme Express, and Ultimate Mind Games.
During the late 1990s and early 2000s, the publisher expanded its console presence by handling domestic PlayStation releases. A key component of this strategy involved publishing budget-priced software, particularly through collaborations tied to the
Simple 1500 Series Vol. lineup. Early efforts in this category include the 1997 release
Defeat Lightning, which established the company's footprint in the budget gaming market.
This distribution model matured with a wave of releases in 2000, including the localized simulation
Roller Coaster World, the train-racing title
Xtreme Express, and the puzzle compilation
Ultimate Mind Games. By 2001, the publisher added
The Kickboxing to this budget lineup. Alongside these genre titles, the company transitioned its popular intellectual properties to home consoles, notably releasing
Comic Party [Limited Edition] and the standard edition of
Comic Party in 2001. The subsequent release of the action-RPG
Tenerezza in 2003 capped off a prolific era of software publishing. Together, these specific titles defined the publisher's strategy of bridging niche visual novels with accessible, low-cost console entertainment for the Japanese market.
