Note: I traveled to Aomori prefecture (day trip) following the prescribed infection prevention measures by the Government of Japan. These include (1) maintaining social distancing, (2) wearing of masks at all times (I used N95), (3) frequent handwashing or use of hand sanitizer. I also avoided crowded, enclosed spaces. I made sure I was never less than 1 meter apart from the person closest to me.
