Looks like just 777s with P&W engines. Shouldn't impact 777-200LRs (don't know if Japan has any flying there) or 777-300ERs as those only have GE engines.
I wouldn't be surprised to see other countries issue a temporary grounding, namely because the cost of doing so is relatively low right now given how many aircraft are parked and others underutilized. I'd imagine there are very few airlines that would be impacted beyond the immediate short-term issue of getting their other aircraft and crews to take over the flying.
EDIT: Wiki shows about 10% of all 777s have P&W engines, and it appears a decent portion of those are in storage already. I'd expect 100ish planes grounded if they grounded all PW4000 777s.
