Interesting because there are so many things to look at:
1. It's the Uguisudani (鶯谷) station
2. Suica logo on the Vending Machine
3. The neon sign of the love hotel and its pricing
4. The girl alone on the right next to the neon sign
5. The reflection of a man using his HDV Camera inside the train
6. The display and handles inside the train
7. All the different colors: blue, pink, green, yellow, orange, light & shadow
