A 7-day private journey across Japan combining cultural immersion and high-speed travel. The route begins in Osaka, includes a visit to Expo 2025, continues through Fukuoka and Kyoto, and leads to a Zen retreat at Eiheiji Temple in Fukui. Afterward, I will relax in a traditional onsen in Awara before concluding the trip in Tokyo. Travel will be by Shinkansen (Green and Gran Class), and I am seeking a companion for my journey.
