Hakone Kowakien (226) - The Reborn Giant of Kowakien Gardens

Re-opened in 2023 with 226 keys, 10 function rooms (largest 1,200 m²), private entrance to Yunessun hot-spring theme park and coach bays for 20 buses. Plenary, team-building in water-slides, and garden–gala all run on foot; Odawara-shinkansen transfers in 35 min.

Lantern-lit paths snake past waterfalls to cypress-wood baths steaming under starry Hakone skies. Delegates brew green-tea cocktails at the forest bar, stroll to a private noh-mask workshop, then dine on wagyu sukiyaki in a glass ballroom where mist curls over mossy stones—business melts seamlessly into woodland wonder.
