The Journey Begins: A Short Trip from Kobe to Arima Onsen

Traveling from Kobe’s Sannomiya Station to Arima Onsen is surprisingly smooth by train.

I first took the Kobe Municipal Subway from Sannomiya to Tanigami Station, then transferred to the Kobe Electric Railway bound for Arima Onsen.
The transfer at Tanigami was easy. It was just a short walk across the platform.

As the train continued, the view outside the window gradually shifted to green mountains, and I could feel the city noise fading behind me.
It was the perfect transition into a peaceful hot spring getaway.

The one-way trip from Sannomiya to Arima Onsen took about 30 to 40 minutes, including the transfer.
It was quick and simple, but something about the changing scenery made it feel like I had traveled much farther.
In just under an hour, I felt like I had quietly slipped away from the city and stepped into a calmer world.
The one-way fare was exactly ¥690, making it a simple and affordable escape for a short getaway.

Arriving at Arima Onsen Station: Welcomed by the Steam

The moment I stepped off the train at Arima Onsen Station, I was greeted by a soft, distinctive scent in the air. It was the kind of smell that could only belong to a hot spring town.

Just past the ticket gate, I spotted a quirky bench designed to look like a traditional bathhouse washing area.
It even had a mirror behind the seat, instantly putting me in an onsen state of mind.

Outside the small station building, I found myself surrounded by gentle mountains and a calm, nostalgic atmosphere.
There was a quiet excitement in the air. It was a feeling of anticipation for the journey ahead that began to rise naturally within me.

With a small roundabout at the station’s entrance, souvenir shops lining the nearby path, and the rooftops of the hot spring town visible in the distance, I took my first steps into the welcoming world of Arima.

Following the Footsteps of Hideyoshi and Nene: Gateway to Arima’s Historic Hot Spring Town

As I left the station and started walking toward the hot spring town, the first thing I saw was a statue of Taiko Hideyoshi.

It honors Toyotomi Hideyoshi, the samurai leader who unified Japan during the turbulent Sengoku period.

Arima Onsen has long been known as one of his favorite retreats.
Not far from the statue is Nene Bridge, named after his wife, Nene.

Standing on the small bridge, I could hear the soft murmur of the stream below and look out over the quiet streets of the town.
It felt like a moment where history lingered gently in the air, mixing with the quiet excitement of setting off on a new journey.

Morning Walk and the Discovery of Arima’s Famous Sweet

As I walked into the town from the station, I arrived at Shinsui Plaza, a small riverside rest area with benches and the gentle sound of flowing water.
It’s a spot many people pass by, but it quietly offers a peaceful moment at the start of your journey.

I sat for a while, watching the stream and breathing in the fresh morning air.
It was one of those places where time seems to slow down, helping you ease into the relaxed rhythm of the town.

After leaving the plaza, I began strolling through the streets and quickly found one of Arima’s most iconic treats: tansan senbei.
These thin, crispy wafers are made with naturally carbonated spring water from the area and have been loved by locals and visitors for more than a hundred years.

Lightly sweet and perfectly crisp, each shop adds its own subtle twist to the flavor.
Trying a few from different stores made me realize how surprisingly varied they can be.

But what I was really hoping to try was something even more unique: Nama Tansan Senbei, a freshly made version of the snack prepared right in front of you.
At Yunohana-do Honpo on Taiko Street, you can watch them prepare each wafer individually using a heated iron mold.

The moment I received one, I could feel the heat in my hand. The texture was soft and floppy, completely unlike the usual crisp version.
And just as I was marveling at that unexpected softness, it started to harden before my eyes.

They call it the “five-second senbei”, because the texture begins changing almost immediately.
That brief transition from warm and soft to crisp and delicate makes it a truly rare and memorable experience.

Later in the day, I would visit Tansan Spring Park, the very place where this naturally carbonated water comes from.
Knowing that the sweetness I tasted had its source in Arima’s own soil made the experience feel even more connected to the town itself.

A Touch of Childhood Wonder: Visiting the Arima Toys & Automata Museum

As I continued strolling through the onsen town, I came upon the Arima Toys & Automata Museum, quietly housed in a building full of character and charm.

This wasn’t just a place for children.
It turned out to be a heartwarming stop where adults could rediscover their sense of play.
Inside, I found traditional wooden toys from around the world, along with mechanical pieces that moved in clever, almost magical ways.
The warm atmosphere stirred a quiet sense of nostalgia.

What stayed with me most were the handcrafted wooden puzzles and wind-up animals that came to life with a simple twist.
Many of the displays were so inviting that I felt like reaching out and playing with them.
Time slipped by without me noticing.

Tucked away in the peaceful onsen town, this little museum offered a moment of calm and joy.
It reminded me how comforting it can be to reconnect with the simple wonders of childhood.

Relaxing in a Footbath and Experiencing Arima’s Geiko Culture

After some time walking through the onsen town, I found a perfect spot to rest: the free footbath in front of Kin no Yu.

I took off my shoes and socks, dipped my feet into the warm water, and immediately felt the tension in my body melt away.
The gentle steam, along with the quiet smiles exchanged among travelers nearby, created a kind and calming atmosphere that felt unique to a hot spring town.
(*Tip: Bring your own towel, or purchase one at a nearby souvenir shop.)

Visiting “Geiko Cafe Ito,” Where You Can Experience Arima’s Cultural Traditions

Arima Onsen has long been loved by many historical figures, including Toyotomi Hideyoshi, the famous warlord who unified Japan during the Sengoku period.
He is said to have not only bathed in the onsen to heal his body and mind, but also enjoyed cultural gatherings with geiko during his stays here.

Geiko Cafe Ito is a special place where visitors can casually experience this traditional geiko culture.

In a relaxed, modern Japanese setting surrounded by photos and artifacts related to geiko, I spent a peaceful and elegant moment.
The geiko staff were incredibly kind, gently starting conversations without any pressure.
During our chat, I learned the following:

• Geiko are traditional Japanese female entertainers who perform dances and music such as the shamisen in kimono, bringing charm to special gatherings.
• Only Kyoto and Arima retain active geiko culture in the Kansai region today.
• Within Hyogo Prefecture, Arima is the only place where this tradition still lives.

This experience deepened my appreciation for Arima’s unique cultural heritage and reminded me that some things can only be felt by being here in person.

On this visit, I ordered a set of matcha green tea and seasonal Japanese sweets.
The slight bitterness of the tea paired beautifully with the delicate sweetness of the wagashi, making for a moment of rest that gently soothed both body and soul.

Seeking Serenity and Natural Beauty in Arima

Finding Peace at Onsenji Temple

After resting my body and soul with a footbath and some sweets, I headed next to Onsenji Temple, a place that preserves the spiritual legacy of Arima Onsen.

As I passed through its small wooden gate, the sounds of the town quietly faded away.
A calm stillness wrapped around me as I entered the temple grounds.

In front of the main hall, I offered a quiet prayer.
That simple moment helped me recover a sense of peace that had quietly slipped away during my travels.

Basic Information: Onsenji Temple

• Address: 1643 Arima-cho, Kita-ku, Kobe, Hyogo
• Access: About 8 minutes on foot from Arima Onsen Station (Kobe Electric Railway)

Embraced by Fresh Greenery at Zuihoji Park

From the temple, I continued on foot and soon reached Zuihoji Park, a peaceful destination known for its seasonal beauty.

The park is most famous for its autumn colors.
Each year from early to mid-November, the maple trees burst into bright reds and golds, creating a stunning scene.

It’s said that Toyotomi Hideyoshi visited this very place and was so moved by the view that he called it a landscape worth seeing over and over again.

This time, however, I visited in late April.
While there were no colorful leaves, the gentle glow of new spring foliage gave the park a different charm.

As I walked along the tree-lined path, sunlight filtered through the leaves above.
Birdsong echoed in the background, and the breeze carried the fresh scent of young leaves.
The entire park seemed alive, and every step reminded me of nature’s quiet strength.

Basic Information: Zuihoji Park

Feeling the Source of Arima’s Famous Springs

Tansan Spring Park: The Origin of Arima’s Carbonated Waters

To end my journey, I decided to explore the hot spring sources that make Arima so unique.
I started with a short walk to Tansan Spring Park, located a little away from the center of town.

This quiet spot is home to one of Arima’s natural carbonated springs, known for its fizzy mineral water.
Long ago, this very water was used to make the town’s beloved local snack: tansan senbei.

When I visited in April 2025, the spring was not flowing.
Even so, the park had a calm and peaceful air.
With its old stone markers and tidy paths, it was easy to imagine what it must have felt like when the spring was bubbling up from the ground.

I sat quietly for a while, letting the surroundings speak for themselves.
Even without water, the place had its own charm.
It gave me a gentle pause before the journey came to an end.

It wasn’t exactly what I expected, but in its own quiet way, it felt like the right way to close the day.

Uwanari-sengen: A Source with Iron and Legend

After visiting Tansan Spring Park, I made my way to Uwanari-sengen, a smaller spot with a name and legend that immediately caught my attention.

The name comes from a local legend.
It’s said that whenever a beautiful woman passed by, the spring would react out of jealousy and burst with hot water.
The word “uwanari” refers to jealousy in old Japanese, especially the kind felt by a previous lover.

The water here contains a high level of iron.
When it rises to the surface and meets the air, it quickly changes color, turning a deep reddish brown.
It felt raw and powerful, like a part of the earth itself had come to the surface.

Standing nearby, I could sense the heat and energy that define Arima’s golden hot spring.
This place was more than just a spring.
It was a reminder of how nature, history, and legend all live together in Arima.

Bathing in the Heart of Arima: Soaking in Kin no Yu

At last, I arrived at the highlight of my journey: Kin no Yu, the bathhouse most closely associated with Arima’s famous golden spring.

As I stepped inside, the faint scent of iron filled the air.
I bought a ticket at the front desk, and after changing in the locker room, I was greeted by the moist warmth that only hot springs seem to carry.

In the bathing area, I noticed the surface of the water had a subtle brown tint.
Steam rose gently from the bath, and I instinctively took a deep breath, feeling my body begin to slow down.

I eased into the water.
From my toes to my chest, the warmth spread slowly and deeply.
It wasn’t just hot.
It was a penetrating heat, the kind that gently works its way inward from the surface.
This was the unmistakable power of Arima’s golden spring.

With each passing moment, I could feel tension melting away.
The fatigue I had carried began to dissolve into the steam that floated quietly through the room.
There was no need for words.
It was a rare kind of stillness, the kind that you simply let yourself sink into.

Wrapped in the golden spring, I felt completely connected to the energy of the land beneath me.

After the bath, I refreshed myself with a bottle of Arima Cider, a local specialty.

Its gentle sweetness and lively bubbles felt perfect after the deep heat of the bath.

It was the perfect final touch to a day that had awakened all five senses.

A Quiet Ending at Zenshuan Gon Soba

After sipping a refreshing Arima Cider following my bath, I chose to end my journey at a peaceful soba restaurant in town, Zenshuan Gon Soba.

Its traditional wooden entrance caught my eye, and as I stepped through the curtain, I was welcomed by a calm interior and the faint aroma of fresh timber.

I ordered the Juwari Nori Set, which included two types of 100 percent buckwheat soba noodles.
One was made from tartary buckwheat, and the other from a variety called Shinano No. 1, grown near the Yatsugatake Mountains.

Following the owner’s suggestion, I first tried the noodles with just a pinch of salt from Akō.

The tartary soba had a slight bitterness, but it was unexpectedly smooth and easy to eat.
It passed through the throat with ease, leaving a clean, light finish.

The Shinano soba had a gentle sweetness and a soft aroma.
It felt more familiar, offering a rounded flavor that anyone could enjoy.

The dipping sauce was made from Rausu kelp and dried bonito, prepared in a way that reflected the local cooking tradition.
The broth had depth, and just a hint of sweetness came through from the kelp.

To finish the meal, I enjoyed a warm cup of the noodle cooking water.
It had a slightly golden color and a comforting taste that lingered in the mouth.

With that final sip, I felt the entire journey through Arima gently come to a close.
