I find these houses to be very beautiful but the ones like this now you only see on display for tourist. I just want to know why Japan got rid of these houses and replaced them with modern type ones?. 0,o

Answer:

Traditional Japanese houses like this are built for hot, humid summer. They are very nice and airy, and feel wonderful when the weather is warm/hot.

The flip side of it is that it's not well-insulated. So it's drafty and cold in winter, and air-conditioning/heater doesn't work well. It has many openings - so security isn't that great, either. (Japan is a relatively safe country, but still.) In short, it doesn't suit the modern lifestyle.

If I were rich, I would love to live in one of these traditional houses in, like, April to October (except June when it's rainy and super humid), and in a modern building the rest of the year.
