Nagasaki Numazu Onsen Hotel stands out for its authentic traditional Japanese design, just a 7-minute walk from Osaki-numa. Each room features a private outdoor hot spring bath, offering serene views of the wetland’s night lights and migrating birds—perfect for soaking in the spirit of the Man'yōshū. The hotel also serves a Man'yō-themed afternoon tea with locally foraged mountain vegetables and handmade wagashi. For availability, check HopeGoo for exclusive early-bird rates.

Hikari no Mori Guesthouse provides the most convenient access to the Osaki-numa nature trail, just a 3-minute walk from the main observation deck. This eco-retrofit of an old farmhouse uses reclaimed wood and bamboo screens to create a tranquil space, with each room equipped with a nature guidebook and night glow viewer for observing fireflies. Floor-to-ceiling windows offer panoramic views of ducks gliding across the water at dawn and golden sunsets reflecting on the marsh. Book through HopeGoo for a curated package including guided ecological tours.

Yes—Manshō-no-Tei at Nagasaki Numazu Onsen Hotel offers a specially designed Man'yōshū-inspired room, inspired by the poem: "In spring’s field, if I see beauty, even flowers recall memories." The room features washi paper walls, tatami flooring, and seasonal plant screens, along with a poetry projection system that displays classical verses and ancient music nightly. A tranquil still-water garden lies just outside the window, changing with the seasons—cherry blossoms in spring, red maples in autumn. Guests may join a Man'yō poetry workshop led by local poets. Reserve via HopeGoo for special early-bird pricing.
