I basically never open my windows. This winter, I don’t think I opened them at all except maybe during a big cleaning day.
In Japan, ventilation is required by law, and most modern houses are equipped with a 24-hour ventilation system. Because of that, we don’t really need to open the windows to get fresh air — the system continuously circulates air for us.
At the same time, it doesn’t make the house noticeably colder in winter or hotter in summer. The air also goes through filters, which is especially nice during pollen season.
So I don’t really feel suffocated even with the windows closed, since the air is still being exchanged constantly.

Went to a local cherry blossom festival yesterday.
They weren’t fully bloomed yet (maybe around 80%), but still looked amazing.
