Radium Kagaya Beitou — an authentic Japanese ryokan without the flight to Japan
Radium Kagaya International Hotel is the only overseas branch of the 118-year-old Kagaya ryokan from Wakura Onsen in Ishikawa Prefecture — a ryokan ranked among "Japan's best for hospitality" for decades. It opened in Taipei's Beitou hot-spring district in 2010 with rare radium hot springs, tatami suites, kaiseki dining, and kimono-clad staff who kneel to welcome you right at your room door.
The Radium Kagaya story begins in Japan in 1906 — the Kagaya ryokan in Wakura Onsen, Ishikawa Prefecture, has been hailed as one of Japan's finest ryokan for hospitality for decades. In 2010 Kagaya chose Beitou for its first and only branch outside Japan, because Beitou is where Taiwan's hot-spring industry was born back in 1896. This 14-storey, peaked-roof building is, in effect, the entire soul of a Japanese ryokan transplanted into the heart of Taipei.
"The moment you step through the door it feels like Japan — kimono-clad staff kneel to welcome you, walk you to your room, serve tea and explain everything. It's a level of service you won't find anywhere else in Taipei."
The heart of the hotel is its onsen. Beitou has a rare 'green sulphur' acidic hot spring containing trace radium — found in only two places on earth, Beitou and Tamagawa in Japan. The water sits at 41–42°C and is mildly acidic. Guests can soak in the nude public bathhouses, in a private bath inside their own room, or book a suite with an open-air onsen on a private balcony. Soaking in mineral water in your own room at night is the single thing guests rave about most.
The 90 rooms span seven types, from standard rooms to suites, all decorated in sukiya style — shoji sliding screens, tatami floors, timber accents and calm, Zen-like tones. Throughout the hotel hang over 850 artworks from Ishikawa Prefecture, including 350-year-old Kutani pottery, Wajima lacquerware and gold-leaf craft, so staying here feels like sleeping inside a living museum.
Dinner is kaiseki at the Tenshou restaurant — a multi-course Japanese meal built around seasonal ingredients following the principle of 'Shun', each dish plated like a small artwork. Breakfast draws equal praise, with fresh sashimi, grilled fish and a full spread of Japanese sides; many guests wear the provided yukata down to breakfast to lean into the ryokan feeling. One caveat: the kaiseki set is a fixed course, so if you don't enjoy authentic Japanese flavours or raw seafood, tell the hotel in advance.
The hotel sits in Beitou, about a 10-minute walk from MRT Xinbeitou Station (red line branch), with a hotel shuttle available. Around it lie the Beitou Hot Spring park, the Hot Spring Museum, the Thermal Valley and the beautiful Beitou Public Library. It suits a slow, restorative trip rather than a city-shopping one — reaching central Taipei by MRT takes around 30–40 minutes.
To be honest about the weak points: many guest reviews feel the price is high relative to rooms that are starting to show their age. The hotel is now 15 years old, some rooms have thin wooden dividers so you can hear neighbours, and the public baths aren't large. But what Radium Kagaya delivers and others can't is a genuine Japanese ryokan experience with omotenashi-level service — if you come for the culture and the hospitality rather than new-build glamour, this is the best answer in Beitou.
