What Is Goza-no-Yu? A Day-Use Hot Spring by the Yubatake Where You Can Feel Kusatsu's History
The appeal of Goza-no-Yu is that you can soak in Kusatsu's hot spring right in front of the Yubatake while experiencing a space reminiscent of the public bathhouses of the Edo and Meiji periods.
While equipped with modern facilities, the building's materials and design incorporate the atmosphere of an old hot-spring town.
A Facility That Recreates an Edo- and Meiji-Era Public Bathhouse
This day-use hot spring is a reconstruction of one of the public bathhouses that stood around the Yubatake from the Edo to the Meiji period, and its name preserves a legend connected to Minamoto no Yoritomo.
It is said that the stone Yoritomo sat on when he bathed came to be called "Goza-no-Ishi" (the seat stone), and the hot water there came to be called "Goza-no-Yu."
Rather than taking these historical events as literal fact, you'll appreciate them more by enjoying them alongside the building and hot spring as a story passed down through the generations in Kusatsu.
Take Note of the Wooden Architecture and the Atrium
With its "tonton-buki" shingle roof made of cedar boards, its shikkui plaster walls, and interiors that make the most of the texture of wood, simply moving through the building before and after your bath becomes a highlight in itself.
The atrium rising from around the bandai (attendant's booth) to the upper floor gives an open feel, combining the impression of a traditional public bathhouse with modern ease of use.
When viewing the building, the points to note can be organized from a perspective different from the hot spring's basic information as follows.
| Location | Points to Look For | What You Can Sense |
|---|---|---|
| Exterior | Cedar-board tonton-buki roof | An old hot-spring cure resort |
| Walls | The texture of shikkui plaster | A calm, refined atmosphere |
| Bandai | Wooden design | Public bathhouse culture |
| Atrium | Vertical spaciousness | An open feel inside the building |
Ki-no-Yu and Ishi-no-Yu Alternate Between Men and Women Daily
Inside there are the "Ki-no-Yu" and "Ishi-no-Yu" baths, and the men's and women's bathrooms switch each day.
Check on-site which one you can use on the day of your visit; you can also make a return trip aiming for the bath you missed.
The Hot Springs of Goza-no-Yu: Enjoy Two Sources, Yubatake Gensen and Bandai Gensen
At Goza-no-Yu, you can enjoy two hot-spring sources, Yubatake Gensen (Yubatake source) and Bandai Gensen (Bandai source), in the Ki-no-Yu and Ishi-no-Yu baths.
Rather than judging by color alone, the key is to sense the feel on your skin and the sensation after your bath, within comfortable limits.
Enjoy Two Sources in Ki-no-Yu and Ishi-no-Yu
Both Ki-no-Yu and Ishi-no-Yu draw water from both the Yubatake and Bandai sources, so you can enjoy free-flowing water from two sources within the same bathroom.
The Yubatake source is an acidic sulfur spring (pH2.08) and the Bandai source is an acidic chloride-sulfate spring (pH1.7), both strongly acidic waters typical of Kusatsu.
The bathrooms switch between men and women each day, but in a single bath you can compare the two sources side by side.
If you want to compare the difference in materials between Ki-no-Yu and Ishi-no-Yu, you can experience both by making a return visit on another day.
Ki-no-Yu, a Bathroom That Showcases Several Kinds of Wood
In Ki-no-Yu, hinoki cypress is used for the tub, hiba for the pillars, oak for the floor, and cedar for the ceiling, creating a space where you are enveloped in the texture of each type of wood.
Since scent and touch are perceived differently depending on the environment and your condition, the best way to appreciate them is to sit quietly and savor the water and architecture as one.
Ishi-no-Yu, a Solid Granite Tub
Ishi-no-Yu is characterized by its tub made of granite, giving a solid, calm impression different from Ki-no-Yu.
The bathroom names indicate the difference in materials, and you can enjoy both the Yubatake and Bandai sources in either Ki-no-Yu or Ishi-no-Yu.
Understanding the Difference Between Goza-no-Yu and Shirahata Onsen
Travelers looking for "Shirahata Onsen" need to be careful not to confuse Goza-no-Yu, the Shirahata Gensen source, and the public bath Shirahata-no-Yu.
Goza-no-Yu uses the Yubatake and Bandai sources, while "Shirahata-no-Yu," which draws from the Shirahata source, is a separate free public bath located in front of the Yubatake.
Sorting out the relationship between the names and the sources makes it easier to read the information boards and maps on-site.
| Name | Type | Relationship to Goza-no-Yu |
|---|---|---|
| Yubatake Gensen | Source name | Used in Ki-no-Yu and Ishi-no-Yu |
| Bandai Gensen | Source name | Used in Ki-no-Yu and Ishi-no-Yu |
| Shirahata Gensen | Source name | Not used within the facility |
| Shirahata-no-Yu | Public bath | A separate bathing facility |
How to Use Goza-no-Yu With Confidence on Your First Visit
At Japanese hot springs, the place to undress, the place to wash your body, and the place to soak are clearly separated.
If you know the order, you can act calmly by following the other bathers around you, even if you feel uneasy about the language.
After Check-In, Keep Your Belongings and Valuables Separate
Once you've checked in, look for the separate men's and women's entrances, undress in the changing room, and then proceed to the bathroom.
There are free valuables lockers in the changing room, and medium-size lockers can be used for 100 yen, so it's reassuring to store your wallet, passport, and the like before bathing.
If you have large luggage, ask at the front desk how it can be stored within the facility.
Ease Your Body Into the Water With a Pre-Bath Rinse (Kake-yu) and a Half-Body Soak
Before entering the tub, wash your body, get used to the temperature with a pre-bath rinse (kake-yu), and then enter quietly.
The two sources at Goza-no-Yu are strongly acidic at pH1.7 to 2.08 and can feel hot, so starting with a half-body soak rather than plunging in deep from the start helps ease the strain on your body.
Don't endure the heat or the stinging; if anything feels off, get out of the tub right away and rest.
After Your Bath, Rehydrate and Rest
After bathing, dry yourself well before returning to the changing room, put on your clothes, and rehydrate.
Rather than walking around the hot-spring town right away, resting inside until your body temperature and breathing settle makes it easier to continue sightseeing afterward.
The flow and purpose of bathing can be summarized concisely as follows.
| Stage | Action | Purpose |
|---|---|---|
| Before Undressing | Store your valuables | Prevent loss |
| Before Bathing | Wash your body | Keep the water clean |
| Before the Tub | Rinse with hot water (kake-yu) | Get used to the temperature |
| During Bathing | Rest without overdoing it | Ease the strain |
| After Your Bath | Rehydrate | Steady your condition |
Bathing Etiquette at Goza-no-Yu: What Visitors to Japan Should Keep in Mind
Hot-spring etiquette isn't a difficult set of manners but common rules for keeping the water clean and being considerate so other bathers can relax.
If you see a sign you don't understand, it's safest to check with the front desk or staff rather than proceeding on your own judgment.
Wash Your Body Before Entering the Tub
Rinse off sweat and dirt at the washing area before entering the tub, and quietly return the stool and basin you used so water doesn't splash on those around you.
Shampoo and body soap are provided at the washing area, but since they are limited in number, avoid monopolizing a spot for a long time.
Don't Put Your Towel or Hair in the Water
The general hot-spring etiquette is to place your small towel outside the tub or on your head, and not put it into the water.
People with long hair should tie it up so it doesn't touch the water, and refrain from swimming, diving, or making big splashes.
Prioritize Consideration for Others When Taking Photos and Talking
In the bathrooms and changing rooms, other people's bodies or belongings may be captured, so please refrain from taking photos.
Follow the on-site signs regarding where photography is allowed inside the building, and check with staff if you are unsure.
Keep conversation to a quiet voice, and don't block the tubs or passageways as a group.
If You Feel Unwell, Skip the Bath
After drinking alcohol, right after a meal, or right after intense exercise, the strain on your body tends to be greater, so decide after resting sufficiently.
People with sensitive skin and small children may feel the strongly acidic water stinging, so start with a shorter bath and get out immediately if anything seems wrong.
The following table contrasts considerate and inappropriate behavior.
| Situation | What to Do | What to Avoid |
|---|---|---|
| Washing Area | Wash your body | Monopolizing a spot |
| Tub | Enter quietly | Swimming or diving |
| Towel | Place it outside the water | Putting it in the water |
| Hair | Tie it up | Soaking it in the water |
| Photography | Check the signs | Taking photos in the bathroom |
Spending Time Inside Goza-no-Yu: Using the Great Hall and Facilities
Goza-no-Yu isn't only for leaving right after your bath; it also lets you rest while gazing at the Yubatake from the great hall on the upper floor.
However, there are no dining facilities inside and bringing food in is restricted, so it's easier to use if you think of it mainly as a place to rest.
Gazing at the Yubatake From Yumoto-no-Ma
Yumoto-no-Ma on the second floor is a 45-tatami-mat great hall that Goza-no-Yu users are free to use, with a full view of the Yubatake from the windows.
While resting your body after your bath, you can enjoy the townscape of the hot-spring town from a height and angle different from viewing the Yubatake outdoors.
Note that the great hall's hours are from 9:00 to 20:00, which differ from the operating hours of the bathing facility as a whole.
You reach the second floor by stairs, and the facility as a whole is not barrier-free, so if you have concerns about getting around, checking in advance is necessary.
Bringing Your Own Bathing Items Makes Things Easier
Thinking separately about what's available inside and what's easy to prepare yourself means you won't be flustered after entering.
- Available inside:Shampoo, body soap, hair dryer
- Easy to bring yourself:Towel, a bag for wet items, drinking water
Towels are not available for rent but are sold instead (face towel 380 yen, bath towel 1,700 yen), so unless you need to reduce your luggage, bringing your own towel makes for smoother use.
Note that yukata for use inside can be rented for 300 yen, which you can use if you want to enhance the hot-spring mood.
Avoid Bringing In Food and Drink
You cannot bring food or drink into the building, and there is no restaurant or general dining space.
However, the front desk sells bottled milk and PET-bottle drinks, which you can use to rehydrate after your bath.
Use the shops in the hot-spring town before or after your visit for meals, and spend your time inside for bathing and resting.
Since the entire building is non-smoking, if you're looking for a place to smoke, follow the local guidance outside the facility.
Check Goza-no-Yu's Opening Hours, Fees, and Access Before You Visit
Once your travel dates are set, it's important to check the opening hours, fees, and closure information in the visitor guide and announcements.
In particular, be careful not to overlook maintenance closures or seasonal differences in opening times.
Opening Hours and Entrance Fee
From April 1 to November 30 it's open from 7:00 a.m. to 9:00 p.m., and from December 1 to March 31 from 8:00 a.m. to 9:00 p.m., with last admission at 8:30 p.m. in both cases.
The entrance fee is listed as 900 yen for adults and 450 yen for children, and presenting an eligible original certificate or identification booklet entitles you to half off the regular fee.
Check the closure information in advance together with the hours for in-building facilities such as the great hall (9:00 to 20:00).
Check Payment Methods and Towels
Credit cards (VISA, Mastercard, JCB, AMEX, AEON Card), electronic money (Rakuten Edy, iD, transit IC, WAON, QUICPay), and QR-code payments (PayPay, AEON Pay) are accepted.
Since towels are sold in the building rather than rented, buy one on admission if you don't bring your own.
Even when it's crowded, don't rush at the front desk; checking the fee categories and the items you need before entering lets you use the facility with peace of mind.
Location Within the Yubatake and Parking
Goza-no-Yu is right in front of the Yubatake, making it an easy place to fit into an itinerary of exploring central Kusatsu Onsen on foot.
Since the facility has no attached parking, if you come by car you'll use paid parking such as the Yubatake sightseeing parking lot.
Because snow, road conditions, and transit operations change with the season and weather, before you set out also check the operation and road information from transit operators and the tourism association.
Summary: Feel Kusatsu's Hot-Spring Culture at Goza-no-Yu
Goza-no-Yu is a day-use hot spring where you can experience, in one facility, two sources—Yubatake Gensen and Bandai Gensen—the difference in materials between Ki-no-Yu and Ishi-no-Yu, and wooden architecture reminiscent of a public bathhouse.
If you're looking for Shirahata Onsen, understanding that the Shirahata source and Shirahata-no-Yu exist separately from Goza-no-Yu will help you avoid getting lost on-site.
Follow the basic etiquette—wash your body before entering, don't put your towel in the water, and follow the signs about photography—and enjoy Kusatsu's hot spring at your own pace according to how you feel.
