Hot Springs in Japan Nanki-Katsuura Onsen Area

Описание: ☆Hashigui-iwa Rocks – Kushimoto
Stretching for about 850 meters from Kushimoto toward Oshima, over 40 rock pillars of various sizes rise dramatically from the sea.
Shaped by long years of marine erosion, only the harder rock remains, creating a scene that resembles the piles of a bridge standing in a row.
☆Around 15 million years ago, magma rose from underground and intruded along cracks in the strata, solidifying into igneous rock dikes.
Later, as the land uplifted, the surrounding softer mudstone was eroded by waves, while the harder dikes remained.
Continued erosion shaped them into their distinctive pile-like forms.
Combined with the legend of Kobo Daishi, this geological process gave birth to the unique landscape of Hashigui-iwa.
☆Hotel Nakanoshima
Located in Nanki-Katsuura, a land of faith and hot springs blessed with deep blue seas and brilliant sunshine, Hotel Nakanoshima offers a truly scenic retreat.
From the observation deck, home to a stone monument of Bokusui Wakayama’s poem “Kumanonada Ryōjō,” guests can enjoy breathtaking panoramic views.
After relaxing in an open-air bath accompanied by the sound of waves, savor a drink and fresh seafood nurtured by the Kuroshio Current.
☆Nakanoshima lies at the entrance to Katsuura Bay, a small island surrounded by two inlets and rocky shores, and part of the scenic “Kii no Matsushima” area along the Kumano Sea.
It is designated as a Special Protected Area within Yoshino-Kumano National Park, established in 1936.
☆Katsuura Bay, enclosed by mountains on three sides, has long been a naturally sheltered harbor protected from the rough waves of the Kumano Sea.
Until the late Meiji period, many sailing ships are said to have anchored in Nakanoshima’s inlets, waiting for favorable winds.
☆Hot Springs
