What’s Orikaeshi (train station)?

Hi,

I did some research on how what route to take from Roppongi to Shinjuku Nishiguchi, but ended up seeing one that says "Tochomae Station (Orikaeshi)"...

What does this mean? Do I rebound here with the same train? Do I change to another train at this station?

*I searched the route from Jorudan.

You get off the train and take another train that departs in the same direction from where you came.

Instead of traveling via Tochomae, you could just get off at Shinjuku and walk from there to your destination in Shinjuku. Shinjuku and Shinjuku-Nishiguchi Stations are only about 400 meters apart from each other.

I checked on google of the train route, there's 2 tracks from Tochomae...

So meaning, I wait for the train that heads to Shinjuku Nishiguchi?

According to Hyperdia (http://www.hyperdia.com/en/)
you take the Toei Subway Oedo Line from Roppongi, get off the train at Tochomae (you arrive on track 4), walk over to track #2 and get on the train to Shinjuku-Nishiguchi which is the next stop.

Or as Uji wrote, get off at Shinjuku station (your train stops at Shinjuku just before Tochomae) and walk 400 meters.

Understood. Many thanks =)

More simple answer.

Subway Oedo line is NOT perfect loop rail track like this.
