What other travelers are saying about Ryusendo Cave
Simply beautiful and absolutely stunning. It felt like I was in another world, and it's definitely a wonderful place worth visiting. The attached science museum is also worth seeing, with many exhibits that both adults and children can enjoy. Inside, there are several parts where you have to climb stairs with elevation changes, so it might be a bit challenging depending on your physical fitness. I recommend wearing comfortable shoes.
This is an excellent and well maintained cave which is well worth visiting. We came on a weekday in November and it was a great experience. Very few visitors - we were alone the entire walk/climb through the cave. It is chilly and wet in the cave so bring appropriate clothing.
Great cave area, Half way through if you want to continue then there are a lot of stairs to go up and down but well worth doing it. The stairs are wooden and with hand rails so makes it safer to hold on to.
A truly magical power spot in Japan.
Ryusendo Cave is not just one of the most beautiful limestone caves I've ever visited — it has an unmistakable spiritual energy that you can feel the moment you step inside.
The crystal-clear underground lake, the deep silence, and the ancient stone formations create a powerful atmosphere that feels both sacred and calming.
If you're looking for a place to reset your mind, recharge your energy, or experience Japan's natural spirituality, this is the perfect destination.
Highly recommended for anyone who loves nature, mystery, and healing places.
Such a cool cave. The water is so clear and it was good to learn about it - English brochure provided. It was cooler temperature in the cave. Unfortunately we did not see any bats. There was also a nice gorge walk right next to the cave entrance too.
The cave is open daily from 8:30 AM to 5:00 PM between October and April, with extended hours until 6:00 PM from May to September. The busiest periods are Golden Week in early May and the Bon festival in mid-August, when over 6,000 visitors may enter in a single day. Peak congestion occurs between 11:00 AM and 2:00 PM. For the clearest views of the underground lakes, winter is the best season to visit, as the water transparency is highest when there is minimal water inflow from rain or snowmelt. The cave maintains a constant temperature of around 10°C year-round, making it comfortable in winter and refreshingly cool during summer.
The cave route includes several staircases, with some exceeding 200 steps, which may be challenging for visitors with limited mobility. Wheelchairs can enter the cave, but visitors must transfer to the facility's own wheelchairs at the office, as standard wheelchairs cannot navigate the narrow passages. Only 2 wheelchairs are available. During busy seasons when the route becomes one-way only, wheelchair users may need to wait for less congested periods to make a return trip. The path can be slippery in parts, and walking sticks are available to borrow from the office. Baby strollers cannot be brought into the cave due to the stairs and must be left at the office.
Photography is allowed inside Ryusendo Cave, though lighting conditions can be challenging. The cave is quite dark except for the LED illumination on the walls and underwater lights in the lakes. Long exposure times may cause moving water to blur, and high ISO settings can result in grainy images. Despite these challenges, the illuminated underground lakes and rock formations offer spectacular photo opportunities. Visitors should note that water drips from the cave ceiling continuously, and dripping increases after rainfall, which may affect camera equipment.
Warm clothing is essential, as the cave temperature remains around 10°C throughout the year, even during summer. A light jacket or coat is strongly recommended. Rain gear or an umbrella is advisable because water drips from the cave ceilings, and this dripping intensifies after rainfall. During periods of heavy dripping, umbrellas and raincoats can be borrowed from the office. Comfortable, non-slip footwear is important as some paths can be slippery. The typical visit takes approximately one hour to explore both the main cave and the adjacent science museum.
Pets are prohibited from entering the cave to protect the ecosystem, though they may be left at the office with advance notice for large or multiple pets. Eating, drinking, and smoking are all prohibited inside the cave. To preserve water purity, visitors must not throw coins into the waterways or underground lakes. There are no toilet facilities inside the cave, so visitors should use restrooms before entering. The rock formations, including stalactites and stalagmites, are extremely fragile and touching them is strictly prohibited. The cave may close temporarily if water levels rise to dangerous levels due to heavy rainfall. Visitors who have consumed alcohol may be advised not to enter due to safety concerns with the steep stairs.
