Highlights of Hot Foot 105

Hot Foot 105, a footbath at Obama Onsen in Obama, Unzen City, is a 105 m-long flowing footbath named after the spring’s 105°C source temperature, where you can warm your feet and relax between stops on your trip.

Rising Steam and Types of Footbaths

Spring water at over 100°C cascades down tiers, sending up steam. In addition to a seated footbath, there is a walking footbath where pebbles stimulate the soles of your feet, and a pet footbath you can enjoy with your dog.

Getting There by Bus

If you take a local bus, it is a 3-minute walk from the Shimatetsu Bus stop Nishi Tozanguchi.

What to Wear and Bring

Choose clothes that are loose around the ankles and shoes that are easy to take off and put on. Keep a towel for drying your feet separate from those for your hands or face; a bag for the used towel is also useful.

How to Use the Footbath

At Hot Foot 105, slowly lower your feet into the water, starting with your toes, to check the temperature. If the heat feels uncomfortable or you feel unwell, take your feet out and rest rather than endure it.

Etiquette When Busy and Taking Photos

When it is crowded, make room for others and keep your belongings compact. For photos, choose an angle that keeps other users’ faces and belongings out of the frame.

Planning Your Visit Around the Weather

Rain, wind, and heat can affect comfort outdoors, so adjust the order of your stops to suit conditions on the day. When the ground is wet, avoid slippery areas.

Slow Down at Hot Foot (Hotto Futto) 105 in Obama Onsen

At Obama Onsen's Hot Foot 105 footbath, warming your feet while slowing the pace of your trip feels just right.

Even on a day spent hopping between sightseeing spots, taking time to sit and look around makes it easier to notice the local atmosphere and the movement of people.

A 105 m Footbath Inspired by the Hot Spring's Source Temperature

Located in Obama-chō, Unzen City, Hot Foot 105 at Obama Onsen is a flowing footbath 105 m long, created in reference to Obama Onsen's source temperature of 105°C.

The sight of hot spring water over 100°C cascading down the stepped water feature and sending up steam is another highlight.

Choose Your View from Where You Sit

When you arrive, do not put your feet straight into the water. Look over the available spaces and your surroundings so you can choose a spot calmly.

In addition to the seated footbath, there is a walking footbath with pebbles embedded in the bottom to stimulate the soles of your feet, as well as a pet footbath you can enjoy with your dog.

Look to the left and right as well as straight ahead. Taking in passersby and the atmosphere of the hot spring town turns your footbath time into part of the journey, rather than just a break.

If you are with companions, find a place where everyone can sit comfortably, and check that you are not blocking passageways or access to the footbath.

Even a slight change in the direction you face can alter the view and how close you feel to the people you are talking with. Be considerate of others as you make the space comfortable for your group.

Rather than rushing to claim an empty seat, allow time for those already using the footbath to move. This helps create the gentle pace that suits a footbath.

Focus on the Warmth

Notice the warmth spreading from your toes, relax your shoulders, and steady your breathing to help let go of the tension of traveling.

People experience the water differently, so enjoy it within your own comfort zone rather than following how others react.

If the heat or the way you feel seems uncomfortable, do not endure it. Prioritize taking your feet out and resting for a while.

What to Wear and Bring to Obama Onsen's Footbath

Clothing that lets you uncover your feet easily, along with something to dry them afterward, makes using the footbath much smoother.

Large bags can be awkward to handle. Pack what you need so it is easy to reach, helping you keep the area around your seat clear.

Choose Clothes with Hems That Roll Up Easily

Tight-fitting clothes with little stretch can make rolling up hems awkward, while complicated footwear can take time to put on and remove.

Clothes with room around the ankles and shoes that are easy to slip on and off let you get ready comfortably without keeping others waiting.

Pulling hard on hems can stretch clothing out of shape or get it dirty, so plan for the footbath when choosing your outfit for the day.

Bring a Separate Small Towel

Keeping the towel for your feet separate from the one you use for your hands or face helps keep things hygienic.

A bag for your used towel lets you pack it away without getting your other belongings wet.

Whether towels are available on site may change, so bringing your own makes planning easier.

A thin towel folds down small, fits easily into a light day-trip bag, and reduces the effort of finding somewhere to dry it after use.

Choose a color or pattern that identifies it as your foot towel to avoid mixing it up with your companions' belongings and make sorting it afterward easier.

Keep Your Bags Compact

Do not spread bags into the passageway. Place them so they fit by your feet or in the designated area.

Keep valuables close to your body and organize things before using the footbath, such as putting devices you want to protect from splashes into a bag.

How to Use the Footbath Comfortably

Preparing your things, checking the temperature, and tidying up afterward in order helps even first-time visitors enjoy the footbath without feeling rushed.

Always give priority to any posted instructions or guidance from staff.

Check Your Surroundings Before Sitting

A seat that looks empty may have belongings on it. Briefly checking with the person next to it before sitting can prevent misunderstandings.

Keep your shoes and socks together, and put anything that might blow away into your bag.

Lower Your Feet into the Water Gradually

Test the water slowly with your toes first, rather than plunging your feet in and disturbing the surface.

If you have concerns about your skin or how you are feeling, refrain from using the footbath and prioritize professional advice when needed.

Here is a brief guide to what to do in different situations.

Situation What to Do Be Considerate
It is crowded Make room for others Keep bags compact
The water feels hot Lift your feet out Do not push yourself
Water droplets remain Dry thoroughly Avoid wetting the floor

Tidy Up After Using the Footbath

After lifting your feet out, carefully dry them with a towel and check that the area underfoot is not slippery before putting on socks or shoes.

Look around your seat for anything you may have left behind, and leave it ready for the next person to sit comfortably.

After putting your shoes on, do not start walking immediately. Check how the soles of your feet feel and how your shoes fit so you can move calmly over steps or wet areas.

If your companions are not ready yet, wait somewhere that does not block the passageway, and move on once everyone is ready.

Footbath Etiquette for Conversation and Photography

In a shared space, it is important to balance your own enjoyment with the peace and quiet of those around you.

Simply keeping your voice a little lower and limiting what you include in photos helps everyone present enjoy a calm visit.

Speak at a Volume for Those Nearby

Sharing impressions of your trip is part of the appeal of a footbath, but loud voices and long phone calls can disturb others' relaxation.

Even with someone who speaks a different language, a smile or a short greeting can make it easier to communicate when making room for each other.

Find a Composition Without Other People

Before taking a photo, check all the way to the edges of the screen and choose an angle that keeps other visitors' faces and belongings out of the frame.

Even a tightly framed photo can capture the mood of your trip: focus on your feet, take a close-up of the water's changing surface, or include your companion's hands.

When it is crowded, do not put photography first. You can wait until things settle down or choose to enjoy the experience without taking photos.

Even when photographing companions, deciding the composition first and finishing quickly helps avoid disrupting people changing seats or blocking others' views.

After taking photos, avoid checking the screen for a long time. If needed, choose your photos after leaving the footbath so the shared space stays relaxed.

Tips for Fitting the Footbath into Your Itinerary

Whether you place the footbath in the middle or at the end of your itinerary affects what you do afterward and how you feel.

Avoid overpacking your schedule, and leave room to adjust your stop according to the weather and your condition.

Stop Between Stages of Your Journey

Sitting down after a walk or before heading to your next destination gives you time to organize your bags and check plans with your companions.

If you are taking a local bus, the footbath is a 3-minute walk from Shimotetsu Bus's Nishi Tozanguchi bus stop.

A plan that lets you put your shoes back on and leave calmly is safer than one that has you rushing off immediately after the footbath.

Change the Order of Your Plans to Suit the Weather

When spending time outdoors, rain, wind, and heat can affect your comfort, so adjust the order of your plans to suit conditions that day.

When the ground is wet, avoid slippery areas and check the condition of the soles of your shoes before setting off.

On days with strong sunshine or cold winds, be flexible about cutting your stay short as your body responds, rather than forcing yourself to sit for a long time.

When the weather is hard to predict, avoid making the footbath your only fixed goal. Having possible places nearby to pause makes your itinerary easier to adjust.

Plan Your Visit Around Your Travel Style

How you fit the footbath into your trip can depend on your companions and the purpose of your journey.

Here are some ways to plan for different types of trips.

Type of Trip How to Include It What to Keep in Mind
Solo travel A quiet break Keep bags close
Travel with friends Time to chat Keep voices low
Family travel Take turns using it Put well-being first

Operating conditions and precautions may change, so check official information and notices both before your visit and when you arrive.

Making the Most of Obama Onsen's Footbath

At Obama Onsen's Hot Foot 105, prepare your clothing and towel, check the water temperature for yourself, and enjoy your time without pushing yourself.

Small acts of consideration with your bags, conversation, and photos make the time comfortable for both your companions and those around you.

Adapt to the day's weather and how you feel, and enjoy it as a place to create a peaceful pause during your trip.

Frequently Asked Questions

A. Hot Foot 105 is Japan’s longest flowing footbath, stretching 105 meters and named after Obama Onsen’s 105°C spring water. Nearby, water from a source hotter than 100°C cascades down a tiered hot-water channel as clouds of steam rise. While soaking your feet, you can watch this striking, visible display of geothermal heat up close.
A. Admission is free. Hours are 10:00 a.m.–7:00 p.m. from April to October and 10:00 a.m.–6:00 p.m. from November to March. It is closed on the third Wednesday of each month, January 4 and 5, during severe weather, and on days when the hot spring source is cleaned. If your Shimabara Peninsula itinerary includes a weekday visit, check the calendar to make sure it does not fall on the third Wednesday.
A. In addition to a seated footbath, there is a walking footbath with small stones embedded in the floor and a pet footbath where you can soak alongside your dog. The walking footbath is designed to stimulate pressure points on the soles of your feet. If you feel severe pain, stop using it rather than forcing yourself to keep walking or soaking.
A. You can use the hot spring’s high-temperature steam to cook seasonal vegetables from Unzen, seafood, and other ingredients, then eat them on a self-service basis. Reception closes at 6:00 p.m. from April to October and at 5:00 p.m. from November to March. Bringing only the amount of food you need is one option. Before using the steam cookers, ask at reception about the cooking time and how to remove your food safely.
A. It is a three-minute walk from the Nishi Tozanguchi bus stop on the Shimatetsu Bus network, or a seven-minute walk from the Obama bus stop served by Shimatetsu Bus and Nagasaki Prefectural Bus. If you are driving, you can use the Unzen City Obama Marine Park parking lot; the fee for a standard car is ¥250. You may also want to combine your footbath visit with a stroll around the hot spring town.
A. Do not count on buying or borrowing a towel on site; bring your own for drying your feet. Pack a separate towel from the one you use for your hands or face, and place it in a separate bag after use. Clothing with hems that can be rolled up and shoes that are easy to take off and put on are also practical choices. Preparing these items is part of planning your stop.
A. Yes. From the seated footbath, you can watch the orange sun set over Tachibana Bay. The facility closes at 7:00 p.m. from April to October and at 6:00 p.m. from November to March, so in summer it may close before sunset. If you are visiting for the view, compare that day’s weather and sunset time with the opening hours.
A. Obama Champon, one of Japan’s three major champon styles alongside those of Nagasaki and Amakusa, is a local specialty. It is said to have taken root during the Meiji era via the sea route linking Mogi Port and Obama Port, and each restaurant offers its own take on the dish. Check the menu to choose whether you want egg, and consider comparing it with champon in Nagasaki City.
