Ironically, Japan will probably be at lower risk for this given their apparent need to appease China / the global community esp. in advance of Tokyo 2020 (as KevinDTW noted) and perhaps their cultural inclination to ignore things and hope they go away, but it should still be a major concern for travelers who are transiting other countries (e.g., Taiwan) where pax may also be banned from transiting should things get considerably worse in the country of departure.

In Taiwan and other countries with aggressive mandatory quarantine programs, I'd worry about being quarantined due to coming into contact (or even the government's perception of coming into contact) with a potential infected person and possibly getting stuck there for 14 days and having to rearrange flights, make new hotel plans, and figure out the work situation. There could also be complications returning to the home country, either with mandatory quarantine or even an outright ban (although not likely in the USA for citizens).
