A resort observation bath above Aoshima and the Pacific — 15 minutes from the airport
ANA Holiday Inn Resort Miyazaki is a large resort hotel just beside Aoshima beach, south of Miyazaki city, where Aoshima Shrine stands on the wave-cut rock platform nicknamed the “Devil’s Washboard”. Its upper-floor “Aoshima Legend Spa” observation bath is open to non-guests from 11:00 to 22:00, and with the airport 15 minutes away by car it is a handy day onsen for travellers in southern Kyushu. There are gender-separated indoor baths and saunas, and an open-air observation bath facing the sea with a sweeping view of the Hyuga-nada horizon, Aoshima island and the Nichinan coast beyond — loveliest at sunrise and dusk. The water is a brownish sodium bicarbonate-chloride spring of the “moor” type, rich in dissolved plant matter, slippery and moisturising; the source is cool, so it is heated and recirculated. The list price is ¥1,100 for adults, but a coupon printed from the official website brings it to ¥800, and university students pay ¥650 with ID, so the real cost is modest. Afterwards use the hotel restaurants or rest hall, and combine the bath with a visit to Aoshima Shrine, a walk on the Devil’s Washboard, the café strip at Aoshima Beach Park, and Miyazaki specialities such as chicken nanban and mango desserts. It is also the starting point for the Nichinan coast drive (Horikiri Pass, the moai of Sun Messe Nichinan, Udo Shrine), which makes it a popular bath on the first day of a rental-car trip or the last stop before the airport. Open daily, but cleaning (10:00–11:00) and group bookings can restrict access, so phone ahead.

Kitago Onsen Hotel Nichinan Kitago Resort
An hour by car from Miyazaki, a resort hotel on a rise in Kitago, Nichinan, ringed by cedar-clad hills. The silky bicarbonate water (around pH 9.5) is known as a 'beauty bath', and the rotenburo looks across the mountains and Nichinan farmland. Day bathing runs a generous 10:00–22:00 — easy to combine with Obi castle town or Udo Shrine. ¥1,200.

A ryokan founded in the early Taishō era, five minutes on foot from Kyomachi-Onsen Station at the foot of the Ebino plateau. Every tub is free-flowing simple spring water, and a day soak costs just ¥300. Highlights are a cave-style private bath (¥500/hour) and an atmospheric open-air bath that alternates men/women after 18:00. A hidden gem 40 minutes by car from Kagoshima Airport on the way to the Kirishima range.
Kitago Onsen Marushinsō
A ryokan in Kitago Onsen, the quiet inland retreat behind the castle town of Obi and the Nichinan coast.

The bubble-jet main bath and separate open-air baths are all free-flowing. Day use ¥600 (revised June 2026), 11:00–19:50 (last entry 19:00).
