Uguisudani (Nightingale Valley)
The area was famous for bird watching in the Edo Period – no TV, so, ya know.
It’s a small valley behind Ueno Park. I don’t think there are any nightingales here anymore, but speakers on the train platform play recordings of nightingale calls all day long.
It’s also famous for love hotels.
And if you want a Taiwanese obasan hooker, just wink at the old ladies on any corner. lol
