In Japan, the Toyota Prius c was sold under what name?

In Japan, the Toyota Prius c was sold under the name Toyota Aqua.

Toyota launched the Aqua in Japan in December 2011 as a smaller, more affordable member of the Prius family. The same NHP10 hatchback was marketed overseas as the Prius c, with the “c” emphasizing its city-oriented size and use. The car combined a 1.5-liter gasoline engine with Toyota’s hybrid system.

The Aqua name was chosen for its association with water; “aqua” is Latin for water. Toyota used the name to suggest clean transparency and a universally valued resource, while reserving the better-known Prius branding for export markets.

The Aqua and Prius c are not different hybrid systems or unrelated models. They are regional names for the same first-generation subcompact Prius variant. The model became especially successful in Japan, ranking as the country’s top-selling new car from 2013 through 2015.
