Knew Japanese houses were cold, but heard they stay at 19 degrees even with heating on all day and I'm shook...🥶🥶

My place is 19 degrees if I don't turn on the boiler, so a few days ago I was eating with my dad, came home, and was like 'why is it so cold?' so I turned on the boiler right away lol

But a Japanese house is 19 degrees even with the heating on..... If I was born in Japan I would've frozen to death ages ago...

I'm the type to wear short-sleeve/shorts pajamas even in winter because I feel stuffy, so Japan is great for travel, but if I had to actually live there, I don't think I could handle the cold houses in winter🥶
