On a personal experience, when I arrived to Tokyo for a month long vacation in Japan, I had planned going to the Tsukiji Market tuna auctions that first day. It was about 2 in the morning, I had just gotten off a plane, not really tired but the jet lag would kill me for sure, so the plan to counter jet lag would be to not sleep that day and rest the day after and sort of get in sync that way.
Now, I don't know how it is now with the new market, but to be able to see the tuna auction you had to be at the market extremely early so, it being 2am seemed a perfect excuse to just walk. I walked for about 2h and when I arrived to the market I found out that day was a holiday in Japan and there would be no auctions that day. Disappointed, tired, I saw on google maps there was an Onsen nearby (around 1h30 away) so I kept walking to Odaiba. The Onsen in question used to be open something like 23h a day which was great for me at 5am.
Now that was one hell of a way to relax after that long walk. Never rested that hard in my life.
