Between 8am and 9am weekdays a (largely empty) train leaves Shibuya station bound for Kichijōji on the Inokashira line every 2 minutes!
Yesterday, though, I entered the twilight zone. Maybe there are fewer commuters, cars or incidents in the week after shōgatsu but yesterday morning the unthinkable occurred, a dream run. No waiting for trains, and even more incomprehensible, not a single red light. Spooky.
As a result I spent almost 15 minutes in the lobby at work, warming my hands on a canned coffee, as I waited for someone with a key to let me inside.
