New JETs have been getting their prefectural placements lately, so if you've been placed in Shizuoka, welcome! The specific placements should be going out sometime in early June, but for now you can take a look around this website to find out some more about Shizuoka-ken. I definitely recommend checking out the Explore Shizuoka link to see a map with some specific popular locations listed. You may or may not know your city yet, but this can at least give you an idea of what kind of stuff is around.
Also, feel free to e-mail any of the AJET Officers if you have any questions. And be sure to join the Shizuoka JETs group on Facebook. Once again, congratulations on being placed in the best prefecture in Japan, Shizuoka!
