One of my favorite NHK World tv shows is
J-Trip Plan, a travel show that gives travel advice to overseas visitors. The
latest episode features Okinawa and has the reporter visiting a pottery shop where she is able to make her own
Shisa, which really tickled me because my fanon version of Onozuka has family in Okinawa, and both he and Yoshizumi bring back Shisa souvenirs for Miyasaka and Kenzaki in
Part 5 of my Haru wo Daiteita fic "Family Visit: Okinawa". She also gets to "swim" in the ocean on horseback (technically, the horse does the swimming) which really appeals to the horse-mad little girl I used to be.
On the downside, I should warn the squeamish that the show (briefly) features some Okinawan delicacies like pig face (full of collagen, which is supposed to be good for your skin) and irabu (sea snake) soup. I've seen the latter featured on a couple of Japanese cooking shows, and while it's supposed to be a tasty and healthy dish, I don't think I'd ever be brave enough to try it!
Although it might be fun to write a fic in which Onozuka goads Katou, Miyaska, and Kikuchi into trying sea snake soup--all he'd have to do is to accuse them of being too chicken to try it! Kikuchi would of course have to prove his manliness to the Prince, and then Miyasaka and Katou would have to eat it too, so as not to be outdone by Kikuchi. Perhaps with Yoshizumi standing by watching with amusement, and Iwaki sighing with resignation at how childish they're being. ^_^
