Next month I'll be travelling to Czech Republic for a couple of weeks and then returning to Japan, where I live. In order to re-enter Japan I will need to have a COVID test before leaving the Czech Republic. This needs to fulfil some strict requirements:
samples must be taken within 72 hours of my departure time
only certain test methods are acceptable (details here), e.g. an antigen test is not acceptable
I need a certificate of the results
I haven't had much luck googling how to get a COVID test in Czech republic, because the search results are all about whether I need a test before entering Czech, rather than getting a test before I leave. Are there facilities in Czech Republic where I can obtain such a test on this kind of time scale?
