YamaGoldfish just talked about it in the AnAn interview. It’s a response to this question:
Where’s your favourite place in Tokyo?
Sakurada-doori. Because it’s the place where you can see Tokyo Tower the best.
This is a street in between Sakurada dori and if you turn 180 degrees towards the road called “409″ something something, there’s a business hotel. It was probably the only landmark I felt comfortable finding by foot. It’s still a pretty long walk to go down this street and follow to Sakurada-dori.
