About this tour
When Mia from our BugBitten team tried this, she got kitted out in full ninja gear and headed into Sarudado cave in Hidaka to train like Mohei, a legendary peasant-turned-ninja who supposedly learned from a tengu spirit in that very spot. It's a quirky blend of local folklore and mild caving activity set in rural Japan's mountain country—the kind of niche experience that draws curious travellers keen on stepping outside the usual temple-and-sushi circuit. The whole thing runs about two hours, gear and post-cave tea included.
Highlights
- Donning an actual ninja costume before descending into the cave
- Training in Sarudado, the cave tied to Mohei's legendary mentor story
- Helmet, gloves, and boots supplied—no scrambling for your own kit
- Warm tea and local sweets waiting after caving to thaw out
- Small-group format in a quiet, off-the-beaten-path corner of Kochi
- Lean into the folklore angle: tengu spirits and peasant-ninja romance
- Moderate caving challenge—not a hardcore scramble, solid for intermediate fitness
What to expect
You'll arrive, get briefed on Mohei's story, and slip into a ninja outfit—a fun touch that sets the mood. Then it's helmet, gloves, and rubber boots for the walk into Sarudado cave. The caving itself isn't extreme; you're navigating a cave space with some scrambling and climbing, but it's manageable if you're reasonably fit. Our take: the real appeal is the blend of local legend and hands-on exploration—you're not just hearing the tale, you're actually training where Mohei supposedly did.
After you emerge, there's a genuine wind-down: hot coffee or local black tea with sweets and fruit. It's a moment to absorb the quiet of the place and chat with your guide. The cave stays cool year-round, so expect a bit of a temperature shift. The whole experience feels intimate and low-key, which suits the folklore vibe.

Good to know
If you enjoy local history woven into activity—not just museum plaques—this delivers. The ninja costume is a playful touch that makes the experience memorable without being cheesy. Small groups mean you get actual attention from your guide. Insurance is included, which is solid. Tea and snacks ease the post-caving chill.
This demands moderate physical fitness; it's not a casual stroll. The cave stay is cool and damp, so bring a change of clothes or a warm layer for after. Not suitable if you have spinal issues, are pregnant, or have cardiovascular concerns—the activity does ask something of your body. The path into the cave can be slippery; sure footing helps. There's no cover beyond the basic activity insurance, so check what that actually protects. Peak season (spring and autumn) may mean slightly bigger groups. Allow at least 2.5 hours door-to-door.
