I haven't followed the pattern of this route for long enough to know whether dates randomly become unavailable and then available again.
You do know the AS calendar only extends out 330 days, right? If you are checking today a random Monday in Nov. 2023 you 3 chances out of 4 to pick a day that AS is not booking for yet, and the one day their calendar does extend to, Nov. 6, 2023, has availability HND-SGN (in economy). Tomorrow Nov. 13 should come in to view on the AS calendar (probably using the calendar trick).
The weekend before Monday Nov. 6th is a holiday weekend in Japan so that may play in to why someone has grabbed J on that day (IOW, Nov. 6th is not a random Monday).
