Otemachi Station: Which Exit for Tokyo Station, the Imperial Palace, and Major Hotels?

Arrived at Otemachi Station and not sure which exit to use?You may be wondering:

“Which exit should I use for Tokyo Station?”
“Which way is the Imperial Palace?”
“Which exit is best for my hotel?”

Otemachi Station is served by four Tokyo Metro lines and the Toei Mita Line.

Even within the same station, the walking distance to your exit can vary depending on which line you arrive on.

The easiest approach is to check your destination first, then choose your exit.

Best Exit by Destination

Tokyo Station / Marunouchi side
→ B4 / B5

Marunouchi Hotel
→ B2b

Palace Hotel Tokyo
→ C13b

Imperial Palace / Otemon Gate
→ C13a

For Tokyo Station Marunouchi Side: B4 or B5

If you are walking from Otemachi Station toward the Marunouchi side of Tokyo Station, B4 or B5 is a useful direction to follow.

Tokyo Metro officially lists:

B4 / B5 → Tokyo Station Marunouchi Entrance

You can walk toward Tokyo Station using underground passages.

However, Tokyo Station is very large.

If you are heading to the Shinkansen platforms or the Yaesu side, you may still have a long walk after reaching the station.

So it is best to think of:

B4 / B5 as a useful route for the Marunouchi side of Tokyo Station

rather than the best exit for every part of Tokyo Station.

Marunouchi Hotel: Use B2b

For Marunouchi Hotel, use B2b.

The hotel officially lists:

Otemachi Station B2b Exit → about 1 minute on foot

The hotel is connected to the underground passage, which is especially convenient on rainy days.

It is also about a 1-minute walk from the Marunouchi North Exit of Tokyo Station.

Palace Hotel Tokyo: Use C13b

For Palace Hotel Tokyo, use C13b.

The hotel officially states that it is directly connected to Otemachi Station through the underground passage from C13b.

Tokyo Metro also lists Palace Hotel Tokyo among the destinations for C13b.

There is also an elevator to street level at C13b.

Imperial Palace and Otemon Gate: Use C13a

If you are heading to Otemon Gate at the Imperial Palace, C13a is a convenient exit.

Tokyo Metro lists destinations around C13a including:

• Otemon Gate
• Imperial Palace
• Kokyogaien National Garden

The Imperial Household Agency also lists:

Otemachi Station C13a → about 5 minutes to Ote-mon Gate

If the Imperial Palace is your destination, head toward C13a rather than the B exits on the Tokyo Station side.

Common Confusion Point: Otemachi Station Is Very Large

Otemachi Station is served by:

• Marunouchi Line
• Tozai Line
• Chiyoda Line
• Hanzomon Line
• Toei Mita Line

Because the station is so large, the distance to the same exit can vary depending on which line you use.

At Otemachi, it is a good idea to check:

the destination name on the station signs, not only the exit number

This can make it easier to stay on the right route.

Tokyo Station and Otemachi Station Are Different Stations

Tokyo Station and Otemachi Station are close to each other, and some areas are connected by underground passages.

However:

Tokyo Station and Otemachi Station are separate stations.

You can walk from Otemachi to Tokyo Station, but the distance to your JR platform or Shinkansen gate may still be long.

If you have a large suitcase and your final destination is JR Tokyo Station, it may sometimes be easier to travel directly to Tokyo Station instead.
