While prominent, larger Japanese corporations were able to institute work from home during the early months of the pandemic, it is still not nearly as widespread of a practice as in the United States or European countries.
Culturally too there are obstacles that Japanese organizations will have to overcome. With strict organizational hierarchies and a tendency for superiors to micromanage (by Western standards) being among the greatest hurdles.
Furthermore, in addition to the previously mentioned workers having to venture into the office just to stamp papers with their hanko seal, smaller organizations are often lacking the infrastructure for work to realistically be carried out outside of the office.
We must consider the fact that even if remote work becomes more commonplace, the majority of businesses in Japan are small and medium-sized enterprises (SMEs). Even excluding those businesses and workers in the service or retail industries, this still represents a huge proportion of the population, and so for the time being work from home is primarily limited to white-collar professions, with the highest percentage of those with WFH policies being employed at larger corporations.
That being said, at those select companies that are instituting work from home policies—and seemingly doing so for the long-term—a number are taking steps to make such a transition possible. Some are providing stipends to help employees outfit their homes to create more conducive work environments.
For this reason, steady demand for electronics, accessories, and other items (peripherals, furniture, etc.) should be expected as a number of Japanese workers prepare for continued remote work and home office situations.
Additionally, solutions that enable communication and collaboration among teams, even those spread out across various geographic locations, will likely see even greater adoption.
