Travel agency H.I.S. Co. says it will offer one-way tickets from Narita International Airport to Bangkok for ¥4,800 from March 15 to May 8.
The discount will apply to some flights on a Thailand-based charter airline, the travel agency said. H.I.S. said it will start selling the tickets next Wednesday.
The move comes as price competition is intensifying in the Japanese aviation market following the launch of flights to and from Japan by low-cost Asian carriers.
The charter airline will operate daily round-trip flights between Narita and Bangkok. For the flight departing Narita on March 15, 100 seats will be available at the discounted price.
