I'm not sure why, but a lot of American celebrities appear in TV commercials for products in Japan. And most of them are ones you'll never see in an American commercial. Maybe they pay better? Maybe they're just more fun?
This commercial is for Boss coffee, and the premise is that Tommy Lee Jones is playing an alien that's learning about life on Earth, and he's landed in Japan. There's a whole series of these, and I believe this is the 12th one. This one is centered in Akihabara, a.k.a. The Electronic District, a.k.a. Geek Kingdom.
This next one is actually my favorite. And don't ask me what any of this has to do with coffee.
