Coco Ichiban is a chain of stores. I'm not sure where you're at so I couldn't tell you. If you can read Japanese here is the website http://www.ichibanya.co.jp/ You can put in the postal code to find one on the website. If you can't read it PM me your location and I'll have my wife look it up.
Indeed, I am. It's a bit annoying though, because he speaks old people japanese, and beyond that i don't see him much. My other friends do a lot more with their homestays and get more practice, so I'm a bit jealous.
Okay, just wondering. I think that there are two things at work in that movie. First is the desire for humor or for something ridiculous. Second is that businessmen with cash to spend experience a very different "culture" than the people who live in the country. So while the movie may show some of the weird stuff that businessmen see, it is not representative of the experience of the typical Japanese.
