Kisen Onsen Shugendō

Kisen Onsen Shugendō (紀泉温泉修験道) is a pilgrimage-style onsen stamp rally founded in 2015 by Nishiguchi Masatoshi, proprietor of Hanayama Onsen Yakushi-no-yu (花山温泉 薬師の湯) in Wakayama City. Inspired by the Beppu Hatto Onsen-dō, the program overlays a bathing circuit on the Kii Peninsula's three great religious routes — Kumano Kodō, Kōyasan, and Ise — so that each stamp doubles as a small act of pilgrimage.

It launched with eight founding facilities, reached 46 in 2019 and 49 by the 5th anniversary in 2020, with a long-term goal of 88 — a number echoing Shikoku's 88-temple pilgrimage. Member facilities span four prefectures: Wakayama, Osaka, Nara, and Mie.

What's in a name

• 紀 (Kii) — the old province of Kii (present-day Wakayama and southern Mie).
• 泉 (Izumi) — the old province of Izumi (present-day southern Osaka).
• 修験道 (Shugendō) — the Japanese tradition of mountain asceticism whose practitioners (山伏 / yamabushi) walk sacred ranges as spiritual training. The name frames the program as a yu-shugyō (湯修行) — bathing as discipline.

The headquarters sits at Hanayama Onsen Yakushi-no-yu in Wakayama City, a unique 26°C cold spring re-heated and bottled into one of the most mineral-dense waters in the country — a fitting starting point for a pilgrim's journey.

The Sendatsu-chō (先達帳)

Your stamp book.

• What it is — a small paper booklet, the 先達帳 ("pilgrim's book"). Each book holds 8 stamp slots.
• Where to buy — any active participating facility (see the Places tab).
• Cost — ¥200 per book.
• Validity — no expiration; collect at your own pace, over months or years.

You can buy a new book at any participating onsen as soon as the previous one is filled; the program allows (and encourages) collecting multiple completed books on the way to the higher Sendatsu rank.

Stamping rules

1. One stamp per bath. Bathe at a participating facility, then ask the front desk to stamp your Sendatsu-chō.
2. No repeats within the same book. You may not stamp the same facility twice in one book. To revisit a facility, you need a fresh book.
3. Across books is fine. The same facility can stamp every one of your eleven books on the way to Sendatsu — that's the intended way to fill 88 stamps.
4. No order required. Visit facilities in whatever order suits your travel plans.
5. No time limit. Stamps don't expire.

The two ranks

The program has a two-tier certification ladder.

名人 (Meijin) — "Master"

The entry rank, awarded for completing one Sendatsu-chō.

• Requirement — fill one book (8 stamps).
• Application fee — ¥2,000.
• Awarded by — Hanayama Onsen Yakushi-no-yu (program HQ).
• What you receive — a Meijin certificate plus the commemorative Kisen Onsen Shugendō towel and other keepsakes.

先達 (Sendatsu) — "Pilgrim Leader" / apex rank

The traditional Shugendō term for a guide who leads other practitioners through the mountains.

• Requirement — 11 filled books = 88 total stamps.
• Awarded by — Hanayama Onsen Yakushi-no-yu.
• Notable — at the 5th-anniversary milestone in June 2020, around twenty people held the Sendatsu rank; the highest-ranked participant had earned it three times over.

How to apply

When a book is full (or you're ready to claim Sendatsu after 11 books):

1. Bring or send your completed Sendatsu-chō(s) to Hanayama Onsen Yakushi-no-yu in Wakayama City — this is the program office.
2. Pay the application fee (¥2,000 for Meijin).
3. Receive your certificate and commemorative items.

Applying in person at Hanayama Onsen is the traditional route; postal applications are also accepted. Contact the program office for the current postal procedure.

Tips

• Hanayama Onsen is unmissable. The HQ facility is itself one of the prefecture's most distinctive baths — high mineral concentration, characteristic orange-brown coating on every surface. Plan to bathe there at least once during your circuit.
• Pair with Kumano Kodō or Kōyasan. Most facilities cluster around the Kii Peninsula's pilgrimage routes; a single trip can easily yield 3–4 stamps if you plan your bathing along the route.
• Watch for closures. A handful of historic member facilities have closed; the Places tab below marks each clearly. Don't plan a long detour without confirming the facility is open.
• Bring your book everywhere. Some smaller facilities only stamp on request — having the booklet visible at the front desk speeds things along.

Earning the Onsen Oni badge

The Kisen Onsen Shugendō Meijin badge is awarded by Onsen Oni moderators to users who have filled a Sendatsu-chō and received the Meijin certification from Hanayama Onsen. Send evidence of completion (the filled Sendatsu-chō, Meijin certificate, or commemorative towel) through the feedback channel and moderators will grant the badge.

Because the program continues toward the higher Sendatsu rank, this badge is repeatable — the number on your tile shows how many Sendatsu-chō you've completed. Reach eleven to match the apex Sendatsu rank and trigger the separate Kisen Onsen Shugendō Sendatsu badge.
