Changdeokgung Palace, inscribed as a UNESCO World Heritage Site in 1997, was built in 1405 and served as the principal seat of the Joseon dynasty’s government for 262 years. Its 32-hectare Huwon garden — a forested hillside landscape of 26 pavilions and centuries-old trees that works with natural terrain rather than imposing a geometric plan — is the finest surviving example of traditional Korean garden design. The last members of the Joseon royal family lived in the palace complex until 1989.

Seokguram Grotto and Bulguksa Temple, inscribed as a UNESCO World Heritage Site in 1995, stand on the slopes of Mount Tohamsan 16 kilometres southeast of Gyeongju. The grotto’s domed granite chamber — designed around a single geometric module governing the entire space — houses a 3.5-metre seated Buddha viewed today through conservation glass, while the temple’s 8th-century stone bridges and paired pagodas include the site where the world’s oldest surviving woodblock-printed document was discovered in 1966.

Gyeongju served as the capital of the Silla Kingdom for nearly one thousand years and holds two separate UNESCO World Heritage inscriptions covering six protected zones, including royal burial mounds that yielded approximately 40,000 artefacts and one of the earliest surviving astronomical observatories in Asia. The city’s extraordinary density of archaeological remains — from grass-covered tumuli to the 80-metre temple pagoda foundation destroyed by Mongols in 1238 — has made it one of the most significant heritage destinations in East Asia.

The Shrines and Temples of Nikkō — inscribed by UNESCO in 1999 — is a 103-building mountain complex built in 1634–1636 as the mausoleum of Tokugawa Ieyasu, founder of the shogunate that ruled Japan for 265 years. The Yōmeimon Gate contains one deliberately inverted pillar; the Sleeping Cat carving is attributed to a sculptor who reportedly cut off his own right hand. Nikkō is 140 kilometres north of Tokyo, with no second UNESCO site immediately adjacent.

Kinkaku-ji — the Temple of the Golden Pavilion — is a Zen Buddhist temple in Kyoto whose gold-covered pavilion was built in 1397 as a shogun’s retirement villa, destroyed by a novice monk’s arson in 1950, and rebuilt in 1955. The Historic Monuments of Ancient Kyoto UNESCO inscription covers 17 properties across Kyoto, Uji, and Otsu, including Byōdōin in Uji 15 kilometres south.

Tōdai-ji’s Great Buddha Hall in Nara is the world’s largest wooden building, housing a 15-metre bronze Daibutsu whose casting between 743 and 752 CE required 437 tonnes of bronze and came close to bankrupting the Nara court. The UNESCO inscription of 1998 covers eight monuments of ancient Nara, including Kasuga-taisha shrine and the Heijō Palace Remains. The nearest second UNESCO site, Hōryū-ji, is 12 kilometres southwest.

The Hiroshima Peace Memorial — the Genbaku Dome — is the preserved ruin of the only structure that remained standing near the hypocenter of the first atomic bomb dropped on a populated city, on 6 August 1945. UNESCO inscribed it in 1996 despite formal objections from the United States and China. The nearest second UNESCO site, Itsukushima Shrine on Miyajima, is 30 kilometres west by train and ferry.

The Historic Villages of Shirakawa-gō and Gokayama in central Japan were inscribed as a UNESCO World Heritage Site in 1995 for their 114 surviving gasshō-zukuri farmhouses — timber structures with steeply pitched thatched roofs built to shed three metres of winter snow without nails. The remote Gokayama cluster operated a classified saltpetre production programme for the Kaga domain under the Tokugawa shogunate. Community roof-thatching (yui) is still practised in Ogimachi.

Yakushima is an island of 500 km² in Kagoshima prefecture, Japan, inscribed as UNESCO World Heritage in 1993 — the first natural UNESCO listing in Japan. Its ancient Yakusugi cedar forest includes the Jōmon Sugi, a tree estimated at 2,000–7,200 years old, and the island’s visual character directly inspired Hayao Miyazaki’s film “Princess Mononoke” (1997). The island’s interior rises to 1,936 metres from a subtropical coast, stacking multiple climatic zones in a short distance.
