Tourists have Ueno Park on their list because of the many museums set in the park, this is located in the northern part of Tokyo.
What I like about it is that it has a vibe, local families wander there, it is noisy and lively, the station has a shinkansen stop for trains to the north, there is a massive shopping gallery in the station with boutiques and not only big department stores, it does not feel as posh as Ginza but is so Japan
By the station, is a hard rock cafe, nothing special, nothing fancy, but for some reason, Japanese people like to queue and stand there for ever,
At the back of Ueno, is a great part with a shrine and a cemetery, not sure how it is called but it is truly beautiful, follow towards the pagoda at the back and you will find it to your left
Ueno also has a modern metro station, very bright and polished, one of those nice ones
