Underground Network

Connected to the Uchisaiwaicho area via an underpass.

Uchisawaicho underpass will be extended to the Iino Building, creating a 300-meter-long passageway. Rain or shine, the arcade will be at your convenience.


Underpass towards Hibiya Park.

The passage connecting to Kasumigaseki Station has a large top light that allows a view of the sky to connect the underground with the ground level.
