Why ‘bleisure’ travel gives short-term rentals like Airbnb a boost over hotels

That may be the case, but WFH began to decline as the pandemic eased and has continued to. Whilst for most people, WFH actually means that - they are not nomadic and need to be at their home most of the time. Only certain sectors, ages and wealth demographics are going to be able to do this - maybe as an alternative to a year out before Uni. Although it is theoretically possible to do some jobs nomadically, not having a permanent home, most people have responsibilities, relationships, possessions and a reason to be based somewhere.

There are also security, insurance, energy cost and productivity issues. And folk WFH are now expected to make regular appearances in the office for face to face interaction, all pandemic restrictions having ended.

This is a new market, but not a game-changing one. And it is likely that the Japanese government will step in at some point with a raft of restrictions that will all but erase it anyway, as they did with the first generation AirBnBs. So don't overcommit yourself financially in this.

Oh, and 'bleisure' is an awful term. Maybe come up with something else.
