I dont live in japan but I did do some research on it and japan its not uncommon to see 100 octane at the pump but the thing is they use i different way to calculate it then us state side,We use "AKI" they use the "RON" system which in turn japans 100 octane would be a lower then 100 octane rating by ounited states measurement but I'm not sure by how much,Ima google rescue real quick.

EDIT: I googled it heres whats up

japan 100 RON Octane x 0.95 = 95 AKI Octane (US measure

so our cheap unleaded usa 91 Octane = 95.5 Octane japan

so thats good news its actually pretty dang close,well my state carrys mostly 93 octane
