Hawaiian Airlines, which has been hurt by a weak yen on its Japan routes, is dropping service to Sendai at the end of September after seeing a lack of growth in that market.

The discontinuation of the Sendai route marks the fourth international destination that the state’s largest carrier has eliminated in the last two years after aggressively expanding abroad. The three-times-a-week Sendai service is currently part of a triangular route that also includes Sapporo, Japan, and Honolulu. 

Hawaiian, which announced the change Monday only in Japan, plans now to make Sapporo a nonstop route both ways beginning Oct. 1 in Honolulu and Oct. 2 in Sapporo. Under the triangular configuration, Hawaiian has been flying nonstop to Sendai before proceeding to Sapporo and then returning to Honolulu.

The Sapporo-Honolulu route began as a nonstop both ways when it was initiated by Hawaiian in October 2012, but when Hawaiian added Sendai in June 2013, the Sapporo route became nonstop only from Sapporo to Honolulu.

“We added Sendai to our existing nonstop service to Sapporo two years ago in order to provide convenient access to Hawaii for the people of Sendai and Tohoku region,” said Takaya Shishido, country director — Japan of Hawaiian Airlines. “Unfortunately, despite two years of solid efforts, we have not seen sufficient passenger growth to justify continuing this three-way route.”

The final flight from Honolulu to Sendai will take place on Sept. 29 with the final flight flight Sendai to Honolulu, with a stopover in Sapporo, set for Sept. 30. Passengers with reservations to fly from Sendai after Sept. 30 will be re-accommodated. The airline will continue to accept reservations for travel between Honolulu and Sendai prior to Sept. 30.

Last year, Hawaiian dropped service to Fukuoka, Japan, and Taipei, Taiwan, and in 2013 discontinued its flights to Manila.

Following the discontinuation of the Sendai route, Hawaiian will serve just three Japanese cities — daily service to Tokyo (Haneda International Airport) and Osaka and thrice-weekly service to Sapporo.
