Questions about modern Japanese culture

Sorry if this is in the wrong place, I couldn't see it fitting better anywhere else.

Do modern houses still have sliding doors?  How prominent are "Western" hinged doors?  How prominent are forks and knives compared to chopsticks?  How prominent are chairs in places such as the dinner table, etc, or is it more common to sit on the floor?  If so, do they use some kind of cushioning?  How many houses utilize push-to-talk intercoms when entering?  Call me a weeaboo faggot or whatever, but are rooms generally as clean as they are in the animes, or is that a utopian scenario?  It's just that I've noticed a severe difference in those rooms compared to, like, MY room.

Anyone have any input?

ok i am in japan right now so I will tell you what i see.

Sliding doors only exist in japanese traditional style resteraunts, bars, and houses. Sometimes there are automatic sliding doors. Japanese style buildings have sliding doors, while western has the hinged doors, Sometimes a combination of the two. Outside though I see more western hinged doors than japanese sliding doors.

Chopsticks are used with anything that are suitable for chopsticks, for example Japanese food, Chinese food, etc. Forks and knives are used most or at all times when eating western dishes. Same with the chairs, Common sense..

All major stores and supermarkets are always far cleaner than they are in the west.
 
But inside japanese houses especially older lower class buildings are crappier than places i've lived in the west. In the ghetto suburbs houses are made out of wood, living conditions I heard were crap.

Only the higher class , new buildings are clean (Tokyo), but it all really depends on the person living in the house.

anyways if you ever decide to come to japan make sure to bring lots and lots of money so you can avoid the lower class dark side of Japan. Living-wise it is almost like a utopia...with almost everything you need right next door, convinient transportation, products, electronics ANIMU, loli etc. Anything you think of that you need you will always find it.

But you can only have access to these things
if you have millions and millions of dollars to spend. If you don't have much money Japan becomes a boring, dull place to live.
