Quick Answer: Which Exit Should You Use?
| Destination | Exit or Direction |
|---|---|
| OIMACHI TRACKS | JR Tracks Gate or West Gate |
| Atre Oimachi | Rinkai Line Exit A1 |
| Curian Cultural Center | Rinkai Line Exit A1 |
| Ours Inn Hankyu | Rinkai Line Exit A2 |

JR Oimachi Station: Which Gate Should You Use?
JR Oimachi Station has four main ticket gates:
Central Gate (中央口)

How to Transfer Between JR, Tokyu and the Rinkai Line
Transfers are possible at Oimachi Station, but the platforms are not all on the same level.
Rinkai Line to JR Keihin-Tohoku Line
According to the Rinkai Line’s official station information, follow signs for:
Exit A1 or Exit B
Both are listed as transfer directions for the JR Keihin-Tohoku Line.
Choose the route that suits your location and mobility needs.
Rinkai Line to Tokyu Oimachi Line
Follow signs toward:
Exit B
Exit B is the official transfer direction for the Tokyu Oimachi Line.
Continue following the Tokyu signs until you reach its ticket gates.
JR to Rinkai Line
Follow the station signs for the Rinkai Line.
The Rinkai Line station is underground, so allow enough time to reach the platforms.
JR to Tokyu Oimachi Line
Follow signs for the Tokyu Oimachi Line and its separate ticket gates.
Do not confuse the Tokyu railway entrance with the JR West Gate.
Rinkai Line Platforms: Why Are They So Deep?
The Rinkai Line platforms at Oimachi Station are located on different underground levels.
- B3 level: Trains toward Osaki, Shibuya, Shinjuku, and Ikebukuro
- B5 level: Trains toward Shin-kiba, including the Odaiba area
Check the direction of your train before going down to the platform.
If you go to the wrong level, you may need to travel several floors to reach the correct platform.
Traveling With Luggage, a Stroller, or a Wheelchair?
Oimachi Station has elevators, but the easiest walking transfer route may not be the easiest accessible route.
The Rinkai Line provides specific elevator transfer information for passengers changing from other railway lines.
If you need a step-free route:
- Check the accessible station map before transferring.
- Follow elevator signs rather than simply taking the shortest staircase.
- Allow extra time between trains.
- Ask station staff for assistance if the route is unclear.
You can check the official Rinkai Line elevator transfer route (PDF, Japanese).
