Soon after departure, the train reaches Koki-mae Station.
Its past—as a stop built for factory workers—still lingers, tightening the air at the window almost imperceptibly.

At the next stop, Kaneage, that tension eases. Written in kanji that literally mean “to raise gold,” the station’s name carries a quiet suggestion of good fortune. It marks an easy threshold at the beginning of the journey.

Nearby lies JGSDF Camp Katsuta, a Japan Ground Self-Defense Force garrison, known for cherry blossoms that reach their fullest bloom each spring—a place that invites a return. A local friend mentions this, then adds, almost as an afterthought, that there is a restaurant nearby where the fish is especially good.

From Nakane station onward, the landscape opens out. Rice fields fill the frame, and the seasons begin to take the lead in what unfolds beyond the windows. In early spring, water pooled in the paddies turns them into mirrors. Summer arrives in green; autumn deepens into gold; winter fades to the pale browns of harvested fields.

It is not that the train moves slowly. Rather, your breathing gradually begins to align. The tempo of the local line—so distinct from express travel— seems to enter the body, settling into rhythm there.

After crossing the Takada bridge, the journey finds its line.

Station names begin to function as captions for the passing scene. From the windows, the Minato Line becomes briefly pictorial. I lift my phone, unwilling to miss the moment, and think—briefly, sincerely—that one day I might bring a proper camera.

Then comes Nakaminato.

The heart of the line, and the station most likely to draw you off midway. Not merely for seafood, but for the way a port town announces itself—through sound, through scent, through a pace shaped by tides.

From the station, the walk to Nakaminato Fish Market feels instinctive. The distance is modest, measured to the rhythm of a town that has always lived with the sea.

A Chance Encounter: The Station Cat

Nakaminato has another reason to be visited—one that cannot quite be planned. The presence of a station cat.

Osamu, once beloved as the station cat of Nakaminato Station, arrived here one day in 2009, apparently by chance. He lingered on the platform, at ease among passing passengers and station staff, and in time— without decision or ceremony— became known simply as the station cat.

It is said that Osamu passed away as if waiting for the start of the station day, slipping into sleep just before work was to begin. That same day, a small farewell gathering was held locally, quietly marking his passing.

Today, a successor known as Mini-samu has gently taken up his place.

Mini-samu comes and goes freely. Station staff greet him with, “Back again after three days,” and think nothing more of it. He brushes against legs on the platform, settles briefly near waiting feet, and leaves behind unguarded smiles.

Whether you will meet him or not is truly a matter of chance. Still, the mere sense that he might be there somewhere on the platform—that possibility alone—adds warmth to the memory of your journey.

There is one more display here—quietly compelling, especially to those drawn to railways.

It takes the form of retired rolling stock. Among them, one car draws particular attention: KeHa 601, Japan’s first stainless-steel diesel railcar.
It was built in a time when no one could have imagined conveniences like smartphones, or the world they would eventually shape.

More than sixty years on, its silver body carries a different presence than it does in photographs. Rather than polished metal, it feels like a surface that has absorbed time itself—holding it, without gloss.

An iron memory set beside the scent of a port town.
It is in places like this that Nakaminato’s appeal deepens—quietly, but unmistakably.

If you allow yourself a sweet detour, the area around Nakaminato Station marks the entrance to what might be called a hoshiimo kingdom. A short walk brings you past specialty shops devoted to hoshiimo—sun-dried sweet potatoes—, alongside others offering sweets made from locally grown sweet potatoes.

Inside one shop, local customers move with easy certainty. They choose quickly, tuck several packets into their bags, and head out without hesitation. Some fill out multiple shipping forms, sending parcels ahead—perhaps as gifts, perhaps simply as a matter of routine. Watching this, it becomes clear that hoshiimo is not a souvenir for tourists, but a food woven into the everyday life of the town.

I, meanwhile, pause before the breadth of choice.
Some pieces glow a deep amber; others are pale, dusted with a natural white bloom. There are hues of purple as well. Cuts vary, thickness varies, even the decision to slice at all. Faced with such abundance, no single measure presents itself.

So I begin by sampling a little of everything, selecting several small bags for myself. Perhaps, after returning to this town a few more times, there will come a day when I, too, can reach for one without hesitation, like locals do.

Before long, attention turns entirely toward hoshiimo. Drawn by the simple desire to taste it now, I step into a nearby café. Hoshiimo gelato, a hoshiimo shake, roasted sweet potato brûlée, a freshly pressed sweet potato Mont Blanc. Paired with a cup of dark-roasted coffee, the sweetness mingles with faint presence of sea air, and I sense the rhythm of my body beginning to soften.

I glance again at the timetable I photographed earlier at the station and decide to let the next train pass. No—perhaps the one after that as well.

Time given to the natural sweetness distinctive to this town. A modest indulgence, entirely at home here.

Beyond Nakaminato, the Hitachinaka Seaside Railway Minato Line does something unexpected.
Despite its name, it does not offer the sea often. The coastline is held back, revealed sparingly. And for that very reason, when the sea does appear, it makes itself felt.

Tonoyama Station is reached by descending a flight of steps from the road above, an uncommon arrangement that resets the field of vision. The salt in the air draws closer; the density of the atmosphere shifts.
Then comes Hiraiso.
Standing on its gently curved platform, the line ahead refuses full disclosure. The tracks disappear just enough to leave what lies beyond uncertain.
That slight absence of foresight suits a journey by the sea.

Between Tonoyama and Hiraiso, near the Sawameki Level crossing, people speak of a particular moment: the train emerging with Hiraiso Coast perfectly aligned behind it. The kind of alignment that yields a decisive photograph—and just as often, slips past unrecorded.
It is not a moment that can be summoned.
It resists intention.

From here on, another highlight emerges. The open stretch of rice fields begins to recede, and the surface of the land grows drier. Furrow lines come into view, and the rhythm of cultivated fields is etched into the passing window. In the closing stretch of the Minato Line, the landscape shifts—from the soft horizontals of rice paddies to the orderly ridges of sweet potato fields. It is a moment when the land’s leading role quietly changes.

The rice field disappears, replaced by the play of light and shadow across the furrows. As the texture of the view transforms, the journey deepens once more.

Passing Minohama Gakuen Station, a different note enters the air—the presence of students, and with them, the sense of what lies ahead. A station newly built for a school and the daily movements it generates; it suggests that this line is not being preserved as a relic, but quietly renewed through use. That ongoing adjustment is written into the landscape itself.

If you choose to step off at Isozaki Station, the path extends naturally toward Sakatsura Isosaki Shrine. A seaside place of worship, reached by a camellia-lined approach, it feels right that a train journey should lead seamlessly into such a space. This ease of detouring—of letting the route remain open—quietly expands the freedom of travel that defines this line.

And then, the terminus: Ajigaura.

The sky opens wide.
The sea draws close.
Ajigaura also serves as a gateway to Hitachi Seaside Park, but the reason to pause here lies elsewhere. At the close of the journey, a gentle sweetness—and a quiet sense of prayer—waits.

One takes the form of Hoshiimo Shrine, and the small café within its grounds. After paying respects, coffee and sweet potato confections follow naturally—a modest happiness set at the very edge of the line.

The other is Hitachinaka Kaiun Railway Shrine. Old rails are worked into its torii gate; a train car is spoken of as the sacred object.

It is not that a shrine has been placed at the end of the journey.
Rather, the railway itself has come to rest here—as something held dear by the land.

A terminus with room to breathe, and a story just strange enough to linger. Together, they close the final page with quiet grace.
