Lost at Tamachi Station?: Which Exit Should You Use?

Arrived at Tamachi Station and not sure which exit to use?

Tamachi Station is much simpler than some of Tokyo’s larger stations, but choosing the wrong side can still send you in the opposite direction.

The easiest thing to remember is:

Mita / Keio University / Mita Station → Mita Exit (West Exit)

Shibaura / msb Tamachi / Shibaura Institute of Technology → Shibaura Exit (East Exit)

Here is the simple breakdown.

Quick Answer: Which Exit Should You Use?

Destination	Best Exit
Mita Station	Mita Exit (West Exit)
Keio University Mita Campus	Mita Exit (West Exit)
Keio Naka-dori Shopping Street	Mita Exit (West Exit)
Shibaura area	Shibaura Exit (East Exit)
msb Tamachi	Shibaura Exit (East Exit)
Shibaura Institute of Technology	Shibaura Exit (East Exit)
Minato Park Shibaura	Shibaura Exit (East Exit)

Mita Exit — The West Side

Use the Mita Exit (West Exit) if you are heading toward:

• Mita Station
• Keio University
• Keio Naka-dori Shopping Street
• Mita and Shiba areas

Keio University officially recommends the Mita Exit when walking from Tamachi Station to its Mita Campus.

The university is approximately 8 minutes on foot from Tamachi Station.

After leaving through the Mita Exit, cross Daiichi Keihin Avenue and continue through the Keio Naka-dori area.

Going to Mita Station?

Use:

Tamachi Station → Mita Exit (West Exit)

Mita Station is a separate subway station served by:

• Toei Asakusa Line
• Toei Mita Line

The two stations are very close, but they are not the same station.

If you are transferring from JR to the subway, follow signs toward the Mita Exit and then toward Mita Station.

Keio Naka-dori Shopping Street

The Mita Exit is also the correct side for Keio Naka-dori Shopping Street.

The shopping street’s official English website directs visitors from JR Tamachi Station through the West Exit (Mita Exit).

It is a useful route for restaurants, small shops, and the walk toward Keio University.

Shibaura Exit — The East Side

Use the Shibaura Exit (East Exit) if you are heading toward:

• Shibaura
• msb Tamachi
• Tamachi Station Tower
• Shibaura Institute of Technology
• Minato Park Shibaura

This side of the station feels more modern, with office towers, pedestrian decks, and newer developments.

msb Tamachi — Use the Shibaura Exit

For msb Tamachi, use:

Shibaura Exit (East Exit)

The complex is connected to the station area by a pedestrian deck.

Official access information lists it as approximately 1 minute on foot from the Shibaura Exit.

This is one of the easiest destinations from Tamachi Station.

Shibaura Institute of Technology

For the Shibaura Campus of Shibaura Institute of Technology, use:

Shibaura Exit (East Exit)

The university officially lists the campus as approximately 3 minutes on foot from this exit.

Once outside, continue straight into the Shibaura area.

Minato Park Shibaura

For Minato Park Shibaura, use:

Shibaura Exit (East Exit)

Minato City lists the walk as approximately 5 minutes from JR Tamachi Station’s Shibaura Exit.

North Gate or South Gate?

Tamachi Station has both a:

North Gate

and

South Gate

Do not confuse the ticket gate with the final direction you need outside the station.

After passing through the ticket gate, look for signs for:

Mita Exit (West Exit)

or

Shibaura Exit (East Exit)

Your destination side is more important than whether you used the North or South Gate.

Which Lines Stop at Tamachi Station?

Tamachi Station is served by:

• JR Yamanote Line
• JR Keihin-Tohoku Line

It does not have a subway platform inside the JR station.

For the Toei Asakusa Line or Toei Mita Line, walk to nearby Mita Station.

Tamachi Station and Mita Station Are Different

This is one of the most useful things to know before arriving.

Tamachi Station = JR

Mita Station = Toei Subway

They are close enough to use as a transfer pair, but they have different station names.

If your route planner tells you to transfer from Tamachi to Mita, you will need to leave the JR station and walk to the subway entrance.

A Common Mistake

The biggest mistake at Tamachi Station is simply choosing the wrong side.

If you are going to Keio University but leave from the Shibaura side, you will be heading away from Mita.

If you are going to msb Tamachi or Shibaura but leave from the Mita side, you will also be heading in the wrong direction.

Remember:

Mita = West

Shibaura = East

That is the easiest way to remember Tamachi Station.

Japan Life Steps Tip

Tamachi Station is easier than stations such as Shinjuku or Tokyo Station because there are really only two main directions to think about.

Before leaving the station, ask:

Am I going toward Mita or Shibaura?

Then choose:

Mita → West Exit

Shibaura → East Exit

That simple check can save you from crossing back through the station.
