The UNESCO World Heritage sites of the former capital Kyoto give unforgettable insights into Japanese history, but across Japan are numerous, less heralded (and less visited) destinations that can transport travelers back in time. Be it the tales unearthed in castle ruins or fortresses that have withstood the tests of time, a journey to Japan’s Kansai region and the islands of Okinawa can offer travelers fresh insights into Japan’s past and the moments that shaped its future.

Japan is a nation of islands of all shapes and sizes, so it makes sense that much of the country’s culture can be found along its stunning, nature-rich coasts. From island escapes and beautiful beaches to natural hot springs and underground waterfalls, here are some of Japan’s best sites for an unforgettable aquatic adventure.

Okinawa is Japan’s southernmost prefecture. Once an independent Ryukyu Kingdom, this beautiful chain of subtropical islands has its own traditions of dance, crafts, music, and karate. The ancient forests in northern Okinawa Main Island and Iriomote Island are home to numerous endemic species, and in 2021 their ecological significance was recognised as a Unesco Natural World Heritage Site.

Japan’s southernmost isles boast nature escapes at every corner, but the northern area of Okinawa’s main island is one of the most exceptional. Here, the subtropical forests of the Yambaru area—which is both part of the Yambaru National Park and a newly designated UNESCO World Heritage site (together with parts of the Amami Archipelago and Iriomote Island)—lures adventurers with its impressive biodiversity.
