The original Western-style wooden station building, which was constructed nearly 100 years ago, will be dismantled following the Tokyo Olympic and Paralympic Games due to its narrow shape and failure to meet fireproof standards.
But elements of its design will be incorporated in a new nearby commercial building separate from the new station.
The new station building, located south of the wooden one, is a two-story structure that straddles the train tracks and has exits facing Meiji Jingu shrine and Omotesando, according to JR East.
Harajuku Station began operating in 1906 with the wooden building completed in 1924 to accommodate visitors to Meiji Jingu shrine, which was built four years earlier, JR East said.
A platform for exclusive use by a special train for imperial family members is located toward Yoyogi Station.
