international maritime travel during coronavirus

My children live in Japan with their mother. Due to the coronavirus, Japan is currently not allowing foreigners (like myself) in if they have been in any of 146 countries (listed here) in the previous 14 days. I am therefore exploring the possibility of taking 14 days to sail in.

If anyone has experience travelling internationally under coronavirus restrictions, or could introduce me to someone who does, I would be grateful to hear from you.

Thank you,

Thank you all.

@NYCAP123 :

• agreed, certainly not a cruise ship, especially given how this all began to spread in Japan!
• I'm talking to the authorities, but also want to talk to independent experts as well, so I can understand the strength of my case before trying to make it

@olderboater :

• from what I've seen so far, Japan's interpreting "exceptional circumstances" very narrowly e.g. deaths/funerals, last visits to dying family members. If you'd heard otherwise, that would be very good news.
• my sons are 15 and 12; they're also foreign citizens, so wouldn't be allowed back if they left now

@Ken Bracewell :

• perfect - I'll drop Nigel a line now

On Wednesday, I cleared immigration in Fukuoka, Japan, having set sea from Vladivostok on 29 September.

The help I received here, particularly Ken's recommendation that I get in touch with Nigel, was a key turning point in my efforts: thank you again.
