Rusk ラスク is a popular sweet snack and omiyage in Japan. It is a sweet twice-baked baguette. I don’t think it is popular or well-known in the US, but for some reason it is really popular here. I see them everywhere, souvenir shops, bakeries, and even the conbini.
It is not anything particularly special, and I have had many types from many places within Japan. They all taste sort of similar– like a very dry, crunchy sweetened baguette slice. It tastes okay, but I don’t really understand the popularity. Most famous is probably the “Gouter de Roi” brand. Recently one of my sensei brought in a “colorful rusk,” which actually has a fruity taste that I kind of like, and the look is rather festive (there were also purple, green, and yellow colors).
Munakatado is a bakery (or pan-ya パン屋) in Okinawa that makes natural yeast breads. It is in a wooded area in Ginowan. They sell many types of breads and baked goods, but also have a vegetarian-friendly lunch (sandwich, soup, and drink). It is really good and a very relaxing location, but I recommend bringing the bug spray (the only tables are outside). After you finish eating, there are a few parks within a short drive to stroll about.
Bakeries in Okinawa are abundant, as well as in all of Japan. They are often labelled as pan-ya パン屋 (literally, bread shop) or ベーカリー bakery. Although bread and pastry is more of a western thing, the Japanese have embraced it and made it their own.
I am lucky to have so many nearby, sometimes it is difficult to choose. Some people shop at the large chain bakeries in the malls or grocery stores, but I prefer the small neighborhood bakeries, even though their prices may be slightly higher (but really not by much, usually only a few yen). Here are some of the ones I like (with google map links):
Bakery Lulujust opened up near me (less than a week!), but already I am impressed. Both times I have gone was in the morning, right at opening time. Very delicious. Pastries, baguettes, savory breads…
Amashokubeika 天食米果 is a recent find in Urasoe. It is fabulous, and specializes in more loaf-type breads, different from what you find in most typical Japanese bakeries. It also lists allergens, and makes some speciality breads.

Munakatado 宗像堂 is also marvelous, and makes natural yeast breads, as well as offers vegetarian lunch sandwich and soup. You can read more in the linked post.

Bakery & Cafe Coo is located in Nakijin, a perfect place to stop by when you visit the Nakijin castle ruins (tip: this place is beautiful with sakura, “cherry blossoms,” during early February).

Maruyoshi 丸吉 is another amazing find in Urasoe, with a great array of savory and sweet. I am incredibly impressed with this bakery.

There are so many more I could add to the list… maybe I will continue to update.
