Yeah! And where are the cowboys in America? And the pirates in the Caribbean? (That movie rocked!) And where are all those bullfighters and dancers in Spain that Hemingway wrote about?
Now seriously, have you ever been to Japan? I haven't, but I can tell you one thing: what you just described is happening in all developed countries. It's called "progress". One of the main reasons of civilization is to make everyone's life easier by solving basic needs, so we don't have to worry about them. As time goes by, civilization advances and creates even more commodities. We've now reached a point on which we don't have to worry about getting food or shelter (as long as you have money, of course), and now we have many forms of entertainment, like videogames. Kids have always played with whatever they have at hand, and will always do. Playing with videogames is fun as well as straightforward: you don't have to worry about finding someone else to play with or a proper place: that's why they're so succesful. I'm not saying that playing always with videogames is good: playing outdoors and exercising is very important, so there must be a balance. Actually, I think that Japanese schools have kendo and judo as mandatory classes in 1st grade or so, so they exercise at least a bit. And I'm pretty sure that not everybody likes videogames and do something else. There's a factor called "individuality", which is the ability of someone to decide what to do by himself.
As for the massive industrialization of the country: well, you can always take a look at England. England was the first industrial country in the world and it has suffered a lot of degradation, but that doesn't mean that the whole country is messed up. There are still plenty of fields. The same applies for Japan: the whole country hasn't become like Coruscant, and it's not likely. Technology has advanced more than our ethics, so we haven't found the point yet on which we can have sustainable development, but we're getting close. Every single day we're learning more about living along with nature, and we're becoming more responsible. You're being defeatist.
The art: well, just like languages, new arts are created and old ones die. It's not a good or a bad thing: it's just natural. Music nowadays doesn't look (hear?) at all like music from just 50 years ago. But we still have music. Barroc paintings don't look at all like Romantic paintings. The same thing applies to any other art form: sculpture, architecture, painting (and all kind of visual art), etc... It's just progress. Unluckily, some good forms of art pass away, but that happens everywhere.
You should also bear in mind that the scale of values in Japan is very different than those of other countries. Sometimes their decissions (working for long periods of time) might seem weird or not appropiate, but that doesn't mean that they're wrong. It's just a matter of point of view.
I don't know how Poland is right now, but I can tell you about Spain, and I know that what I just said is happening, and I'm sure that in most countries is happening exactly the same. Progress and the changes that it carries with don't have to be bad at all if you learn to adjust to them. You can't expect to have samurai walking on the streets until the end of time, just like you won't see many druids in northern Spain woods nowadays.
Wow, that was long. Excuse me if I bored you
