Looking down Ueno-Okachimachi area, with several trains running through. A narrow path along the train rail with many people walking is Ameya-yokocho, or just Ameyoko, where you can buy many things with really cheap price.
In you follow up the rail, you can see Ueno station and green Ueno park at the far distance, where Panda lives 😉
This section of Yamanote line is the one of the most busy parts over the whole Yamanote line. Especially in the morning, you are squeeeezed so hard, your lap top in a back pack can break!
