The Toyota Aqua is a full hybrid electric subcompact/supermini hatchback (B-segment) manufactured and marketed by Toyota since 2011. The nameplate is exclusive to the Japanese domestic market, as the vehicle was exported to overseas markets as the Prius c, leveraging the popularity of the Prius hybrid car nameplate and marketed as the smaller alternative to the Prius liftback.

The Japan Mobility Show (ジャパンモビリティショー) (TMS) is a biennial auto show held in October–November at the Tokyo Big Sight, Tokyo, Japan for cars, motorcycles and commercial vehicles. Hosted by the Japan Automobile Manufacturers Association (JAMA), it is a recognized international show by the Organisation Internationale des Constructeurs d'Automobiles, and normally sees more concept cars than actual production car introductions which is the reason why the auto press see the show as one of the motorshow's big five.
