Wow interesting! Today I thought I had completely missed the express train to Shinjuku (non-stop from my station), misremembering that it leaves at 6:14. But it leaves at 6:21.
The train and I arrived at the station at the same time, but from past experience, not only will all the seats be sold out, there will be a queue of people hoping to buy tickets. Today there was a queue of people, but the tickets were still being sold! Wow so I got a ticket, hopped on the train and zooom arriving in Shinjuku 20 minutes after departure.
