We had booked on the short tour but because we had arrived early and there were some cancelations we were allowed to go on the long tour. Because of my limited language ability. I found the first half of the tour was a little long, I would have preferred something more visual and tactile. The tunnels in the second half were exciting to go through. Though I would have liked the light show to be a little bit more educational. I would like to thank the staff for being so nice.

I joined the 45-minute short tour in July 2026. Even though it was extremely hot outside, the drainage tunnel, one of the tour stops, is kept at around 15 degrees, so it was really comfortable. Apparently the long tour lets you go further inside. The projection mapping apparently changes each season. Overall the quality is hard to believe for something free, and I think anyone who loves civil engineering, history, or finding out the "why?" behind things will definitely enjoy this spot.

I joined the fully reservation-only guided tour at 14:00. There's a surprising amount of walking from the reference room to the actual remains, so comfortable clothes and sneakers are the way to go. It's good exercise. Inside the old tunnel, the main highlight, there were visual effects like projection mapping, making for a magical space you rarely see elsewhere. Also, seeing up close the complex structure of the underground drainage tunnels and the huge piles used to stop landslides really drives home how impressive civil engineering technology is. The diorama in the reference room was also elaborate and helped me understand the history of this place. At Ryuosha, which we stopped by along the way, you can get a goshuin with an unusual design. There are photo-worthy spots all over, like the stone turtle statue, so the visit flew by. Landslide countermeasures may be a somewhat unusual theme, but it's a facility that's well worth seeing even for adults.

Finally got a reservation!! At reception they handed me a small penlight, which got my heart pounding. The opening history talk was satisfying for adults but seemed hard for kids, so I was a bit worried. But once we went outside and started exploring tunnels you normally can't enter and big drainage wells, it felt like a little adventure, and the kids' excitement hit max; they looked like they were having a blast. At the final projection mapping my wife was happy too, so I'm glad we went! No wonder reservations are so hard to get.

Do you all know what a "landslide" is? Just like the word says, it's "the ground sliding," but it's a genuine sediment disaster that has led to major disasters in the past💡 A facility where you can learn about these "landslides" is the "Kamenose Landslide History Museum" in Kashiwara City, Osaka Prefecture☘️ This area, with the Yamato River flowing nearby, has long been prone to landslides, and apparently landslides have even dammed the Yamato River and caused it to flood😳 I joined a guided tour to learn about Kamenose, which is deeply tied to landslides, and the guide showed us drainage tunnels, an old railway tunnel, and more!✨️ I got to learn about "landslides" while feeling Kamenose's fresh air, and even enter places you can only get into on the guided tour, so it was a wonderful time with both learning and a break from the ordinary!☺️✨️ The projection mapping in the abandoned tunnel was especially impressive and super fun!🔥 Thank you for such a valuable experience!☘️ Address: 28-2 Toge, Kashiwara City, Osaka Prefecture Hours: 9:30〜16:30 Closed: Mondays (the next day if Monday is a holiday), year-end and New Year holidays
