Chosen for their special connection to the Yamanote Line in Tokyo, a lucky couple exchanged vows on board a specially reserved train Monday as part of East Japan Railway Co.’s celebration of the 50th anniversary of the introduction of its series of lime green cars.

JR East chose the story of Nobuhiko Suzuki, 27, and Sayaka Tsuchiya, 28, as the most fascinating of all submitted by applicants: While dating, the couple would meet on car No. 6 on the train on their commute to Shinbashi Station for work.

Photos of the newlyweds were hung in the train together with words of appreciation addressed to the guests. A video of a re-enactment of the marriage proposal was repeatedly played on screens above the doors throughout the ceremony.

The pair walked to car No. 6 between some 150 guests, who applauded the announcement of their union.

“I want to cherish the bonds with the family and friends that we have confirmed during the preparations,” said Suzuki.

People who happened to be on the platform at Ikebukuro Station, where the train began its circular journey, greeted the newlyweds with cheers.

Oct. 14 has been designated train day to commemorate the beginning of the first railway service between Shinbashi and Yokohama stations, in 1872.

The Yamanote Line went into service in 1903 and the full loop was completed in 1925. In 1963, the company launched its lime green cars. However, a new series with a stainless steel body was introduced in 1988.

The special lime green train used to celebrate Monday’s wedding is currently in service to commemorate the anniversary.
