Hanzomon Station Tokyo
Hanzomon Station (半蔵門駅) is in the Kojimachi district of Tokyo’s Chiyoda ward and serves one of Tokyo’s most elegant neighborhoods.
Hanzomon is named after the Hanzomon Gate of the Imperial Palace Tokyo, just four minutes' walk east. The Hanzomon Gate is where Shinjuku-dori Avenue [part of Route 20] starts, going as far west as Kabukicho in Shinjuku ward.
Hanzomon Line
In turn, the station gives its name to the whole subway line that it forms a part of: the Tokyo Metro Hanzomon Line. Hanzomon Station is code-named Z-05 on the Hanzomon Line. It opened in 1982. There are no transfers at Hanzomon Station, but Kojimachi Station, on the Tokyo Metro Yurakucho Line, is just four minutes' walk west along Shinjuku-dori Avenue from Exit 2 of Hanzomon Station.
Think "Hanzomon Station" and think "cafes, bakeries, eateries, patisseries." Every exit of the station opens out onto mostly quite elegant places to eat, snack or just enjoy a cup of coffee. Hanzomon provides access to a number of well-known Tokyo places.
At its southern end are Exits 1 and 2, which come out at basically the same place, serving the Kojimachi business district. From here it's an 8-minute walk south-east to the National Theatre, and the imposing, modern Supreme Court building next to the Theatre. Across from the Theatre and Court is the Sakurada Moat of the Palace.
Exit 5 is at the northern end of the sation and comprises a stair exit on the main street, and an elevator also on the main street, but a little back. Across the road from Exit 5 is the Hotel Monterey Hanzomon, highly regarded for its very reasonably priced rates in such a prime location, for its friendly English-speaking staff, and great breakfast! The whole length of the station can be traversed underground. Read more about this station in Tokyo.
