William Kumanichi points out a shortage of corona antigen test kits, with testing at hospitals thus prioritized to “essential workers” and those with symptoms - and even then, shortages persist. A vending machine for test kits at ￥3,000 apiece has been installed at the Sakuramachi mall However, it too is now sold out (the phrase 入荷待ち, nyūka-machi, means “awaiting stock”), and when it will be restocked is unknown. Still, if you’re unsure if you’ve been infected, I suppose visiting a vending machine is better than waiting in a crowded doctors office. https://kumanichi.com/articles/542201
