Hakone Hotel Kowakien (箱根ホテル小涌園, 1297 Ninotaira, Hakone-machi, Ashigarashimo-gun, Kanagawa) is holding a "Summer Sweets Buffet" (サマースイーツビュッフェ) for three days only, from Saturday July 18 to Monday July 20, 2026 (a national holiday). The venue is the newly expanded garden-side seating area, where floor-to-ceiling windows look out over the hotel's Japanese garden, creating a relaxed and open atmosphere for an afternoon sweet-tooth session.
The menu brings together around 15 varieties of sweets, including a fruit sandwich on the hotel's own freshly baked shokupan (milk bread), seasonal fruit tarts, jelly, cake, and financiers. A highlight for families is the "drawing pancake" (お絵描きパンケーキ) station, where parents and children can decorate their own pancakes together. Light savory options — Kowakien ramen and potato fries — are also available, along with coffee and tea.
