That's indeed very weird policy.
Also be prepared to pay for more than $300 per person.
Are the prices for travel around xmas that much higher? Otherwise advance purchase J class from Tokyo to Okinawa run as low as 11,000 JPY. I don't count for getting it that cheap, but buying it for up to 15,000-20,000 JPY shouldn't be a problem.
