You have to learn English, or get left behind by every nation that gets this: S.Korea, China, India... Doesn't matter if it is 'hard' or 'difficult' or even unfair: English is the de facto international language and is going to be for a couple of generations, no matter what happens to America in the near term. Just about nobody's going to lean Japanese anymore unless they have family connections... or want to play at making them.
kids don't want to learn English you need to get the birch out and start beating from the Amakudari down to the parents responsible.
More bad news, for Japan.
