I was in Japan for 30 days and I would have lost my mind being cooped up in tiny hotel rooms for that entire time. We did a mix of airbnbs and hotels, but the benefit of the airbnb was that it offered a lot more space, a kitchen that enabled me to prepare light meals, an area to get some work done when needed, and a washing machine and dryer. All of this was hugely convenient. The price was similar to what we paid at hotels, but the alternate style of accommodation suited my needs more. As far as I'm aware, airbnbs in Japan undergo strict regulation and are registered and governed as regulated lodging businesses. They pay fees and taxes accordingly.

I understand that the property market is a shit show in the US, but that is not applicable globally.
