I had influenza two decades ago, the only time I’d ever missed work, and the memory of severe misery remains. Kumanichi reports that the number of influenza cases reported by designated hospitals has risen dramatically in the last few days to about 1,200 severely miserable people. This might be attributed to the close contact people have at shrines and homes during New Year celebrations.
Health insurance covers most influenza vaccination (infuruenza yobou sesshu, インフルエンザ予防接種) cost, with out-of-pocket less then 2,000 yen. A list of hospitals which offer subsidized vaccinations is attached. They’re likely alike, so the one closest to you is probably best. In the meantime, sanitize your hands and keep them away from your mouth. Please direct specific questions to the comment section below. - William
