What is it like to stay in the oldest inn in Arima Onsen, one of the three major hot springs in Japan?

Arima Onsen, one of the three major hot springs in Japan, is close to Osaka, Kobe, Kyoto, and Nara. No matter which city in the Kansai region you are in, it takes less than an hour and a half to get to Arima Onsen by car, making it very convenient. If you're traveling to Kansai, why not take a dip in the hot springs at Arima Onsen, surrounded by mountains? The 'Gosho Bessho' is the oldest hot spring inn in Arima Onsen, founded in 1191, as old as Arima Onsen itself. The main building of Gosho Bessho now is a three-story wooden building full of historical charm. The design was inspired by the essay 'In Praise of Shadows' by Junichiro Tanizaki, a representative figure of Japanese aestheticism. It uses the contrast of light and shadow to show the classical beauty of Japan. The inn is filled with a rustic artistic atmosphere everywhere. The items placed seemingly casually at the corners of the stairs and along the corridors are basically antiques, and the traces of time flow inadvertently in every corner. The hot spring water of Arima Onsen has a strong sulfuric acid taste, and the color is golden yellow (a bit like the color of soil). This is the so-called 'golden soup'. In addition to the men's and women's baths, the inn also has rooms with private baths, where you can enjoy the 'golden soup' of Arima Onsen, the 'first divine spring in Japan', in your room. The food at this ancient hot spring inn is naturally worth mentioning. Even guests who are not staying at the inn come here for its reputation. In addition to Kobe beef, there are fresh seafood from Akashi Port and seasonal vegetables from the surrounding Rokko and Maya Mountains. You can taste all of these here. Despite the variety of dishes, Gosho Bessho modestly calls its cuisine 'rustic mountain cooking'. Arima Onsen is surrounded by mountains on three sides. You can enjoy cherry blossoms in spring and red leaves in autumn. If you come to Kansai in these two most beautiful seasons, why not escape from the crowds during the peak season and take a dip in the 'golden soup' in the mountains?
