The last-train home is no one’s idea of the perfect end to an evening, but if you don’t fancy the karaoke – and sour-fuelled wait for the first train – then it’s unavoidable. You know what I’m talking about. Everyone all drunkenly squashed together and holding each other up after a night of booze, cigarettes, and yakitori.

I wouldn’t say it’s all bad, though. I once got talking to a builder who was working at the top of the Tokyo Sky Tree. He saw my camera and after talking a little about photography he got his phone out and showed me a load of cool photos and movies that he had taken while climbing up and down the tower. There’s some irony there that after a day high up away from everyone and everything in Tokyo, this guy has to squash himself into a crowded little train to get home!
