I thought I should give you a tour of a modern Japanese house. They are quite nice! And they are roomy since they make very efficient use of space.

Some houses have a gated entrance

Some also have Japanese style gardens

In Japanese houses, you must take off your shoes before entering and you leave them in this area by the door

The downstairs hallway

A traditional looking room of a Japanese house (notice the tatami mats)

The computer room of a Japanese house

A Japanese living room (notice the kotatsu table to the right which is a heated table for the winter)

A Japanese kitchen

Upstairs hallway

A Japanese bedroom

 

Japanese bathroom (you shower on the left side THEN enter the bath)

I did not post a picture of the toilets, as they look pretty much the same. However, there are some key (high-tech) differences. For example, the toilet seats are heated, some in residential houses flush automatically, they often make sounds (to cover the sound of you using the restroom), you can select a big or small flush, and they have a spray feature.

 

So, I suppose that is pretty much a standard Japanese house.
