Karatsu Castle, located in Karatsu City, Saga Prefecture, was originally built in 1602 by Terasawa Shima no Kami Hirotaka, a vassal of Toyotomi Hideyoshi. Although the castle was dismantled during the Meiji Restoration, it was reconstructed in 1966 and now functions as a museum. The castle's fifth floor features an observation deck, providing breathtaking views of Karatsu Bay and the surrounding landscape.
