Beppu Onsen Tamago-do

Onsen Tamago-do (おんせんたまご道, "Way of the Hot Spring Egg") is a side quest to the Beppu Hatto Onsen-do bathing route. You eat your way through Beppu's onsen eggs while you work through its baths, and finish with a towel you cannot get any other way. Eighteen shops take part, most of them in the Kannawa and Myoban quarters.

The current round is the second. It started on 25 November 2025 and ends on 30 November 2026.

How to earn

This badge is awarded by Onsen Oni moderators to users who have earned the Tamago-do special rank certification. Send a photo of the certificate or the towel through the feedback channel and moderators will grant the badge.

How the campaign works

1. Buy the guidebook. The Onsen-bon (温泉本) is ¥660, sold in Oita bookshops and convenience stores and at the tourism association. An Onsen Tamago card is bound into it.
2. Buy an egg at a participating shop, and they stamp that card. One shop, one stamp.
3. Bathe at Onsen-do baths as you normally would, collecting bath stamps in your spa passport.
4. Apply once you have enough of both, and collect your towel.

What you can earn

• Special rank (特別段位認定): 4 egg stamps and 8 or more bath stamps, ¥1,000. Capped at the first 200 applicants, so it can close before the campaign does.
• Special Meijin (特別名人認定): 8 egg stamps and 88 bath stamps, ¥3,000. No cap, everyone who qualifies is certified. The towel is yellow, embroidered in black with 別府八湯温泉道名人.

Bath stamps only count on a card you have not already cashed in for a rank. For the special rank, any rank does, from Shodan (8 baths) up to 10-dan (80 baths).

Rules that catch people out

• Egg stamps go on the egg card, nowhere else. They are not bath stamps, and a stamp on the wrong sheet does not count.
• Last year's card is dead. A 2024-2025 card cannot be used, and the two cannot be added together.
• One stamp per shop. A second stamp from the same shop voids the card.

Applications go to the Beppu Hatto Onsen-do office inside the Beppu City Tourism Association (Renga Hall 1F, Suehiro-cho 1-3), weekdays 8:30 to 17:00. Post is accepted.

The eighteen shops

Prices and selling hours are the guidebook's, and plenty of shops stop the moment they sell out. The cooking time is the interesting part: it is why no two of these eggs taste alike.

Three of the eighteen have no page in our catalog, because they are places to eat rather than to bathe: Ajidokoro Yoneda, Yuzawaya, and Momotaro, which is a café inside Yuya Ebisu.

Taking part since the first edition

• Jigokumushi Kobo Kannawa, Furomoto. Steamed egg, ¥150, sold 10:00-18:00. Steamed 10 minutes, and you can order a single egg; the yolk is left just short of setting.
