Daimon Station, Underground metro station in Hamamatsuchō, Japan
Daimon Station is an underground railway hub in Tokyo's Hamamatsuchō area where the Toei Asakusa Line and Toei Ōedo Line intersect. Multiple platforms are arranged to allow smooth transfers between the two lines, with various exit points connecting to street level.
The station opened on October 1, 1964, as part of Tokyo's infrastructure expansion for the Olympic Games. This opening marked a turning point in the city's metro system development.
The name comes from Shiba Daimon, the main gate of Zōjō-ji temple that once stood nearby, connecting the station to the area's religious landmarks. This historical reference remains visible in how locals describe their neighborhood.
The station serves more than 200,000 passengers daily, so it can get quite busy during peak hours. Allow extra time for transfers and consider visiting during quieter periods if you prefer a less crowded experience.
During planning, the Ōedo Line section was meant to take the name Hamamatsucho, but officials chose to keep it as Daimon for consistency with the existing Asakusa Line. This naming decision shows how practical concerns shape urban infrastructure.
