Every February, thousands of men strip down to a white cotton loincloth and plunge into near-freezing water or a crush of bodies competing for a sacred stick — and a growing number of foreign visitors are joining them. If you’ve seen footage of Okayama’s Saidaiji Eyo or Aichi’s Konomiya Hadaka Matsuri and thought “I want to try that,” the first practical question is simple: where do you actually get the fundoshi, and how much does it cost? Here’s what to know before you book.
What a Hadaka Matsuri Actually Requires You to Wear
“Hadaka matsuri” translates to “naked festival,” but participants aren’t actually nude — the standard outfit is a fundoshi (a long strip of cotton tied into a loincloth), white tabi socks, and often a hachimaki headband. At the biggest events, like Saidaiji Eyo at Kannonin Temple in Okayama (held every year on the third Saturday of February), several thousand men wear this exact combination while dousing each other with cold water before the main scramble for the sacred shingi sticks at midnight. Konomiya Shrine’s naked festival in Inazawa, Aichi, follows a similar format on a different February date. Both are men-only for the main night event, though Saidaiji also runs a separate, smaller daytime event for women and children in different dress.
Where to Rent or Buy a Fundoshi Set
Most participants don’t rent a fundoshi so much as buy one, since it’s a single-use cotton garment that gets soaked, muddied, and often torn in the crush. In Okayama, the official “Eyo fundoshi” participation set — fundoshi, tabi, and sometimes a hachimaki — is sold by the Saidaiji Eyo Preservation Society and by sporting-goods and workwear shops near Saidaiji Station in the weeks leading up to the festival. Some hotels and ryokan in Okayama City also stock sets for guests who book a festival package. If you’re arranging participation through a local tour operator or a company “kumi” (participation group), the set is frequently bundled into the registration fee rather than sold separately — ask this explicitly when you register, since showing up without one and expecting to improvise is a common mistake.
Don’t expect to find fundoshi rental counters the way you’d find kimono rental shops near Kyoto’s temples. This is a much smaller, more local market, and supply is tightest in the final week before the festival, so sort this out early rather than planning to buy on arrival.
How Much It Costs
Budget roughly 3,000–6,000 yen for a basic fundoshi, tabi, and hachimaki set bought locally in Okayama or Inazawa. Mid-range participation packages sold through tour operators, which bundle the clothing with event registration, group placement, and sometimes a post-festival hot bath or meal, typically run 10,000–20,000 yen. At the splurge end, some operators offer English-speaking guide support plus accommodation and transport as part of a multi-day package, which can run well over 30,000 yen depending on the operator and whether it includes lodging during the festival’s peak dates when Okayama hotels sell out. Always confirm current pricing directly with the shrine’s preservation society or your tour operator, since neither publishes a fixed rate card and prices can shift year to year.
Joining a Kumi Group and Registering in Advance
Unlike most festivals you can simply show up to, Saidaiji Eyo and Konomiya’s naked festival expect participants to register as part of a kumi — an organized group, traditionally a company, neighborhood association, or club. Foreign visitors almost always need to go through a tour operator, a local hotel’s festival package, or occasionally a university/exchange group that has an existing relationship with the shrine. Independent walk-up participation is possible at the margins but is genuinely difficult without Japanese language support and local contacts, so book your spot at least a few months ahead of the February date rather than deciding on a whim after arriving in Japan.
Best Timing and What the Night Actually Involves
Saidaiji Eyo runs on the third Saturday of February, with participants gathering from around 7–8pm, cold-water purification (mizukake) through the evening, and the main shingi scramble beginning at midnight and lasting around 30–45 minutes. Temperatures in Okayama in February regularly sit near freezing, and you will be wet for hours before the climax — this is genuinely demanding, not a costume photo op. If your main interest is in Japan’s winter folk festivals more broadly rather than the extreme physical side of a naked festival, it’s worth comparing the vibe to a gentler midwinter tradition like the Hachinohe Enburi dance festival in Aomori, which runs on similar winter dates but without the cold-water ordeal.
Getting There
Saidaiji Station is on the JR Ako Line, about 20 minutes by local train from Okayama Station, which itself is roughly 50 minutes from Osaka and under an hour from Himeji on the Sanyo Shinkansen. From Saidaiji Station it’s a 10–15 minute walk to Kannonin Temple. For Konomiya’s festival, Konomiya Station is on the Meitetsu Nagoya Line, about 20 minutes from Nagoya. Both festivals draw large local crowds, so trains and nearby parking fill up well before the evening program starts — plan to arrive in the afternoon if you want a decent viewing spot, even if you’re not participating yourself.
Common Mistakes and Practical Tips
- Assuming you can rent a fundoshi on the day. Local supply is limited and most visible stock disappears early; buy or arrange your set in advance.
- Underestimating the cold. You’ll be doused in cold water and standing around wet for hours before the main event — bring a dry change of clothes, a towel, and warm layers for immediately after.
- Skipping group registration. Showing up solo without a kumi affiliation makes participation in the main event very difficult; this isn’t a spectator festival you can casually join.
- Not planning for your soaked gear afterward. Your fundoshi and tabi will be wet, muddy, and generally not something you want in your main luggage — pack a sealable bag, and if you’re moving on to another city the next day, consider sending your main suitcase ahead so you’re not hauling it through a crowded festival night; the rules for same-day hotel luggage forwarding are covered in this guide to takuhai cutoff times.
- Treating it like a costume event. The fundoshi itself is simple, but the context is a genuine religious purification ritual — treat the shrine grounds, the priests, and the other participants with the same respect you’d show at any sacred site.
If the idea of renting unusual formal wear for a one-off Japanese occasion appeals to you beyond festivals, the same rent-don’t-buy logic applies to Western formal events too — see our guide to renting a tuxedo or formal suit in Japan for the equivalent process on the other end of the dress-code spectrum.
