Confusing subway in Tokyo!

My newly met friend Ian (at the K's House) and I were to go to a Wadaiko (Japanese drum) lesson in Kawasaki-city (in Kanagawa prefecture).

Subway system in Tokyo is quite complicated and we were freaked out.

We were not freaking out any more when we took these pictures, but we were pretending as if we were just so freaked out ('cuz I thought it might be visually interesting for this weblog). Do we look freaked out?!
