Start Point : Onarimon
Destination : Harajuku
cost 260yen

1. and how far...?
4.7km

so i can just jump on Onarimon station and it will take me straight to harajuku? i wanted to see the cosplayers..how far away is the bridge from the station?

The station and bridge are next to each other.

In my experience, the best day to see cosplayers is on a Sunday. from Harajuku station exit/entrance, go immediate right-then up the ramp/hill. The bridge is at the top of the hill on the right. As an extra, you, and if you're interested, you might want to go a little further across the bridge and you'll see the entrance to Meiji shrine. There's a huge torii gate and walkway to the main shrine area. On a weekend, you'll have a good chance of seeing a Japanese wedding. I got to see three in one day. The traditional outfits and the processions, etc. are great to watch.
