Which country in Asian is it best to live in?

Idk. China if you want a rural life, SK if you wanna shop for cute stuff and are rich, Singapore if you want your kids to have a nice education, and if you want low cost for basic living.

I have been to a few but not all. However I would have to say Japan

I've only been to Japan but loved it.

India

I would have to say Japan. I love the culture, ergonomics, and the food.

East timor

Japan 🇯🇵, hands down.

Philippines

With English
India .. if you like people.
Singapore .. if you like places and system and expensive.

Without English
Japan but very expensive.
Thailand

I'd maybe go for Japan as you have snow in Hokkaido, lovely rural areas to the south and nice cities/cool culture. It's also small so you could travel around quite quickly.

Indonesia @YukikoAmagi

Mongolia or Tibet. Somewhere I can be solitude.

South Korea is nice

My fav is Japan.
