I don't think the expectation is the entire extra 30k people allowed in per day will be using ERFS system. I know a lot of Japanese were equally reluctant to leave the country due to the valid fear they might test positive before their return flight to Japan and be stuck in a foreign country longer than expected. With the removal of that test for them as well I expect a larger percentage of Japanese might be willing to travel internationally and make up a good percentage of that extra 30k.
