Yumoto Onsen in Iwaki Fukushima

Overview

John Daub embarks on an ambitious 13-onsen tour across Fukushima Prefecture, beginning with Yumoto Onsen in the coastal city of Iwaki. This video serves as the opening installment of what promises to be an epic journey from the seaside waters of Iwaki to the mountain regions of Aizu-Wakamatsu. John, who once lived in Iwaki nearly two decades ago, returns to rediscover this historic hot spring resort during peak autumn foliage season.

The highlight of the video is Yumoto Onsen's distinctive konnyoku (mixed-gender) outdoor bath—a rare find in modern Japan where men and women bathe together, though typically with towels worn around the waist. John navigates between scalding mineral pools, marvels at the crystal-clear spring water emerging directly from the ground, and shares candid reflections on his own journey from onsen-shy newcomer to passionate advocate of Japanese bathing culture. The tour concludes inside the attached traditional ryokan (inn), where John finds himself wandering the lobby in a towel after accidentally encountering other guests—leading to an amusing end to the stream.

Japan Travel Tips

• How to get there: Yumoto Onsen is located in Iwaki, Fukushima Prefecture, accessible via local train lines connecting to Fukushima's coastal region. Iwaki is on the Joban Line running south from Fukushima city toward Tokyo.
• Best time to visit: Autumn (October–November) offers spectacular momiji colors; winter (December–February) provides dramatic contrast with snow falling while you bathe in hot water.
• Onsen etiquette essentials: Always wash thoroughly before entering the bath—use the provided buckets or spigots to rinse off. Do not bring towels into the water (or keep them minimal). At konnyoku onsens, most modern bathers wear small towels around the waist.
• Temperature caution: Natural onsen waters can exceed 50°C—always test with your hand or feet first before fully submerging. The mineral-rich pools can cause burns if you're not careful.
• What to look for: White mineral deposits on rocks indicate genuine natural hot spring water. Clear, odorless water suggests low sulfur content—many people find this more pleasant for extended soaking.
• Costs: Ryokan stays typically include dinner and breakfast (kaiseki cuisine), ranging from ¥10,000–¥30,000+ per person depending on luxury level. Day-use onsen visits are usually ¥500–¥1,500.
• For foreigners: Don't be shy—overcoming the initial awkwardness of communal bathing opens up one of Japan's greatest cultural experiences. Most other bathers are senior citizens and quite accepting of newcomers.

Japanese Language & Culture Notes

• Onsen (温泉): Naturally heated underground water emerging at least 25°C above local groundwater temperature. Must contain at least one of 19 designated elements (sulfur, chloride, sulfate, bicarbonate, etc.) to legally qualify as onsen. Yumoto Onsen features sodium chloride (natrium) waters without the strong sulfuric smell many expect.

• Konnyoku (混浴): Literally "mixed bathing." Once common throughout Japan but now increasingly rare due to social changes. Modern konnyoku etiquette typically involves wearing a small towel (shanpu) around the waist. Most visitors tend to be elderly couples or those specifically seeking the traditional experience.

• Ryokan (旅館): Traditional Japanese inn featuring tatami rooms, futon bedding, yukata robes for guests, communal baths, and multi-course kaiseki meals. Staying at a quality ryokan with attached onsen represents the quintessential Japanese travel experience.

• Yukata (浴衣): Light cotton summer kimono worn at ryokan—typically after bathing, before bed, or to onsen towns. John mentions wearing the yukata after bathing before heading to meals.

• Momiji (紅葉): Autumn leaves, particularly the vibrant red Japanese maples that paint the landscape October through November. The contrast of red momiji against gray onsen rocks makes autumn the most photogenic season for hot spring visits.

• John's onsen journey: Honest reflection that it took him two full years in Japan before his first onsen soak—he was too shy to be naked with strangers. His initial reaction of "why would you do that?" transformed into regret over wasted time. A common experience for many foreign residents.

Food & Drink Guide

No specific food items appear in this video, as John focuses primarily on the onsen bathing experience. However, the ryokan setting implies the full ryokan experience typically includes:

• Kaiseki (会席料理) — Multi-course haute Japanese cuisine served at ryokan, featuring seasonal ingredients prepared in various traditional methods (grilled, simmered, raw, fried). Usually 8–12 courses for dinner.
• Haagen-Dazs ice cream — John spots a Haagen-Dazs vending machine in the ryokan, indicating this establishment caters to international guests.
• Milk and soft drinks — Common vending machine offerings at ryokan for post-bath refreshment.

People

• John Daub — The host and creator of Only in Japan Go. An American who has lived in Japan for over 30 years (at the time of filming), John first came to Iwaki, Fukushima 18 years prior to this video. He candidly shares his initial shyness about onsen culture and his eventual conversion into an onsen enthusiast. His warm, conversational style and honest self-deprecating humor define the video.

• Mia-san (未亜さん) — A staff member at the ryokan whom John encounters in the lobby while still in a towel. She appears to help manage the situation as John wraps up his stream.

• The Musician — An elderly gentleman John identifies as one of the onsen's founders, seen playing music in the ryokan common area.

• The Anonymous Bathing Guests — A male guest whose head John spots during the brief indoor bath exploration. Their presence cuts short John's filming attempt.

Key Takeaways

1. Fukushima is an onsen paradise waiting to be explored — With 13 distinct onsen on John's tour, the prefecture offers extraordinary variety from coastal to mountain settings.

2. Don't let shyness hold you back — John waited two years to try his first onsen and deeply regretted those "wasted years." The experience is worth overcoming any initial awkwardness.

3. Natural onsen varies widely — Not all hot springs smell like sulfur. Yumoto Onsen's sodium-rich water is clear and odorless despite being 100% natural.

4. Autumn/winter is the best time for onsen — The contrast of cold air and hot water, combined with autumn foliage or falling snow, creates the most memorable bathing experience.

5. Konnyoku isn't what you might imagine — Forget the "paradise" fantasy—modern mixed bathing involves towels, elderly company, and mostly relaxed, modest behavior.

6. Test the temperature — Natural onsen waters can exceed 50°C (122°F). Yumoto's 59°C pools will definitely burn exposed skin if you're not careful.

Notable Quotes

00:32 John Daub: "We have a konnyoku onsen, which is male and female together, like co-ed, right? But the problem is they gave me special permission to film here so there's nobody there except for us. It's kind of a disappointment."

02:06 John Daub: "Yeah, at konnyoku onsen, it's normal not to go completely naked... People wear towels around their waist."

02:50 John Daub: "It's not the paradise that you'd think. The women that you do meet are probably in their 80s. The guys are probably mostly naked."

05:34 John Daub: "I lived here about 18 years ago, and it's a shame they didn't make it to this onsen. When I first came to Japan, I'll be perfectly honest with you, I didn't know about this onsen. I was too shy to get into the bath."

05:55 John Daub: "I said, why would you go naked with a bunch of people? It doesn't make any sense to me. Boy, was I wrong."

06:14 John Daub: "Oh my, was I regretting not going in. All those wasted years, right?"

07:29 John Daub: "Even if it's raining, you have this covered area, which is really nice. You can hear the pitter patter of the water falling into the bath here and just completely relaxed in the hot water."

13:56 John Daub: "For the next week or so, I'm going to be going around all over Fukushima looking at different onsen, different baths, different rooms, different lots of food. Thirteen places. There's no stopping."
