Overview
Five subway lines meet beneath Otemachi's office district, north of Tokyo Station. Otemachi Station handles subway trips across central Tokyo, while the neighboring JR station serves Shinkansen and Narita Express trains. Underground passages connect them, but their platforms are separate.
That distinction matters when comparing nearby hotels. A short walk to an Otemachi entrance doesn't necessarily mean an equally short route to Tokyo Station's long-distance trains.
Lines and connections
The Marunouchi Line runs one stop to Tokyo Station before continuing toward Ginza and Shinjuku. The Hanzomon Line provides a direct ride to Shibuya, so both lines can take you to major shopping districts without a transfer.
The Tozai Line serves Nihombashi to the east and Iidabashi to the west, while the Chiyoda Line runs directly to Omotesando. Toei's Mita Line adds connections to Jimbocho and Suidobashi. Follow signs for the correct line because the five sets of platforms occupy different parts of the station complex.
Airport access
Narita Express trains depart from Tokyo Station, not Otemachi. You can walk there through the connecting passages, but leave enough time to reach the JR platforms before departure.
For Haneda Airport, one option is to continue to Tokyo Station, take the JR Yamanote Line to Hamamatsucho, and transfer to the Tokyo Monorail. Otemachi itself has no direct airport train.
Station area
Otemachi serves the office buildings and restaurants on the northern side of Tokyo Station and Marunouchi. Exits open onto different blocks, so a building's designated exit is more useful than the station name alone.
Mitsui Garden Hotel Otemachi is about three minutes from Exit A2, near the Marunouchi Line, or five minutes from Exit A5. These walking times begin at street level.
What's nearby
The Ote-mon entrance to the Imperial Palace East Gardens is about five minutes on foot from Exit C13a. Admission is free. Inside are landscaped gardens and the remains of Edo Castle. Check the opening calendar before visiting.
Good to know
Choose your exit before heading upstairs. If you need an elevator, consult the station's barrier-free map rather than assuming the nearest numbered entrance has one. Allow extra time when changing lines or continuing through the passages to Tokyo Station.
