Jetstar Japan Co., Ltd. is a Japanese low-cost airline headquartered in Narita, Chiba. Initially planned to commence flights in late 2012, it launched ahead of schedule on 3 July 2012. The airline serves destinations across the Asia-Pacific region, using a fleet of Airbus A320 aircraft.

A low-cost carrier (LCC) or low-cost airline, also called no-frills, budget or discount carrier or airline, is an airline that is operated with an emphasis on minimizing operating costs. It sacrifices certain traditional airline luxuries, for cheaper fares. To make up for revenue lost in decreased ticket prices, the airline may charge extra fees such as for carry-on baggage. As of April 2020, the world's largest low-cost carrier is Southwest Airlines, which operates primarily in the United States, as well as in some surrounding areas.
