Sushi, Sushi, Sushi! So fresh it's nearly unbelievable; never seen anything like it in the UK. I say nearly unbelievable because we did visit the Tsukiji Fish Market and saw the scale of their fishing operation for ourselves. Unfortunately it's obvious why the Tuna fish are endangered.
Ramen - we should eat more of this! Noodles in a broth, normally topped with spring onion, tempura prawn or other meat
Yakatori...Japanese name for a chicken skewers; tasty all the same
White rice (sticky so you can eat it with chopsticks) included with every meal. Tasty, but not exactly low GI...likely to make you dizzy!
No sign of Pizza Hut anywhere in Japan, but they do take pride in serving fresh McDonalds!
