Also look for shaved ice, which stores advertise with a blue and white banner with a big red kanji splashed across it. It comes in all sorts of flavors, but I like mizore (mee-zo-reh), which is a diluted sweet syrup...
On our first trip - we had good luck finding "exotic things" in department store food basements. Don't know about V8. But I've made a note to find some (or something similar) day of arrival or next in Tokyo. My husband - more than me - gets really "dwimmed" with high temps - suffers from fatigue - being light-headed - etc. - and V8 Juice is his "sovereign cure".
BTW - while I'm on the topic of "exotic things" - is Milk of Magnesia sold in Japan? Don't know that I'll need it. But buying it when I arrive is easier than taking it through airport security.
I really have a strong feeling that the OP's friend has heat issues. Don't we all traipsing around outside in a city that's over 90 degrees for 4 hours in the afternoon? Robyn
