I tried to remember to take a picture of every meal I ate in Japan. Skipped a bunch of breakfasts since they were similar, and most of the snacks too, but here's a sampling.
Minced tuna roll, prawn and avocado spring rolls.
Pork noodle bowl at the Sophia University cafeteria.
Fish roe, octopus, jellyfish.
Cuttlefish with egg sauce.
Champagne mouse and mussel soup.
Sushi lunch purchased on street outside of university, a bit the worse for being carried around.
Sweet and sour chicken and egg drop soup at a Chinese place.
Seafood salad, tofu two ways, duck, fugu at the onsen.
Salmon sushi and tuna roll at Narita airport sushi bar.
