Japan is home to some of the world's most enduring treasures, both natural and man-made. The Horyu-ji Temple in Nara is widely recognized as housing the oldest wooden buildings in the world, dating back to the late 7th century. In the realm of nature, the Jomon Sugi, a massive Japanese cedar on the island of Yakushima, is estimated to be between 2,170 and 7,200 years old, potentially predating the established nation itself. Additionally, the Nishiyama Onsen Keiunkan, a hot spring hotel in Yamanashi, has been in operation since 705 AD and is certified by Guinness World Records as the oldest hotel in the world. These relics highlight Japan's deep-rooted respect for tradition and preservation, making it a unique 2026 destination where one can physically interact with nearly 1,300 years of continuous commercial history or gaze upon living organisms that have survived several millennia.
