Here is the actual calendar the airport which shows Japanese priests at some kind of shrine.
It’s possible the image was swapped for the sake of not being able to find the original in higher quality, or it’s the work of AI recreating the image in a strange way.
Either way, kudos to the devs for recreating the interior down to the placement of the poster and the calendar, but a weird substitution indeed as there is no significant Catholic/Orthodox history in that area of Japan.
