Yep. But in Japan there is no such thing as a family doctor or GP. Closest is a doctor of internal medicine naika

Interesting. In fact there's quite a bit of difference between the two, https://mana.md/whats-the-difference-between-a-general-practitioner-and-an-internist/

But there's also already concern that we're running out of GPs in other countries, e.g. https://www.cbc.ca/news/canada/toronto/oma-declining-number-medical-school-students-family-medicine-1.7182901 - so perhaps this is just a glimpse of the future.

Were it so serious, you would be identified and put on leave or whatever was deemed appropriate for the circumstances. It would not be anonymous but compartmentalised.

That's not as bad, but it's still a case of an employer knowing far more about my medical health than I'm used to.

In more populous areas, mobile clinics (think RV buses) will be brought to offices to conduct the exams.

Interesting idea. Would certainly make it easier to get it done when the clinic is brought to you.

As it so happens I just got the email from my company about the medical check. It needs to be conducted by the end of October.

Good luck!
