Due to the shinkansen timings, I arrive rather early in Tokyo. Basically I had to check out of the hotel by 10am, and I'd already exhausted the very limited nearby delights of Hamamatsu, so there wasn't much reason to hang around for long. It looked like waiting for the 11am shinkansen would get me there at late lunchtime, which sounded like I could easily end up very hungry. There's typically a certain amount of faff before you can really set about finding a meal; I wouldn't want to do it with all my luggage (especially given how cramped restaurants tend to be in big cities, and Japan in particular), and I wasn't sure there'd be much near my hotel.
So I decide to rock up before 10am and get the first train possible. In fact, this turns out to be an extra-express train with only a handful of stops, so I'm in Tokyo by 11.40 and a bit stuck. Previous hotels have let me check in early, but I suspect this one (which seems more modest) probably won't. On the other hand, I can't see anywhere tempting to eat in the station, and I don't want to leave because I'll lose the ability to use my shinkansen ticket to reach the hotel if I exit the barriers. Plus, I'd have to pay to store my luggage, if I could even find an empty coin locker, which seems frankly unlikely.
I'm staying in the Grand House Chang Tee Hotel, which at least sounds impressive, even though it's a modest building on a narrow side street in a suburb (Ikebukuro).
