The nice thing is 7-11 has ATM's outside 7-11's too, such as at the T-CAT bus station in Tokyo. So it's not that hard to find them, and you won't ever be that far away from cash. I'd just recommend having a pocket wi-fi with you so you can always get online and find the nearest 7-11 ATM.
7-11's are ubiquitous in the larger cities. Don't forget, you can also use your ATM card at Japanese Post Office locaitons as well. Forget using your card at Japanese bank machines.
