For many travelers, Japan begins and ends with the classic Tokyo–Kyoto–Osaka Golden Route. It’s iconic for a reason, but it’s far from a comprehensive experience. My fifteenth trip to Japan (I’d stopped counting at some point) was when I finally stayed three nights in Gunma and realised I’d been skimming the surface for two decades.
Most of my friends thought soaking in different onsen on consecutive days would get boring fast. I understood the logic — they pictured one bath, then another, then another, and assumed the novelty would flatten out somewhere around day two.
What actually happened was the opposite. Each town in Gunma had its own character, its own water, its own pace. By the end of three nights I hadn’t started to repeat myself — I’d started to understand something. Japanese domestic travellers have known for a long time what most foreign visitors haven’t discovered yet: that the countryside and the quieter prefectural towns are often where Japan is most itself. The cities are extraordinary, but they’re performing for you. Out here, life is just happening.
This guide covers three prefectures within one to two hours of Tokyo by shinkansen: Gunma, Niigata, and Nagano. All three are easy to add to any itinerary — first-time visitors included. You don’t need to choose between the Golden Route and something more interesting. You can do both. But if you’ve already done Tokyo and Kyoto and want to understand what you missed, these are the places to start.

How I Chose These Side Trips from Tokyo
These side trips from Tokyo meet three simple criteria:
- Easy access from Tokyo: 1–2 hours by train or shinkansen
- A clear contrast to major cities: nature, tradition, or craft over concrete
- Tourist-friendly but uncrowded: rewarding without feeling overrun
1. Gunma: Japan’s Underrated Onsen Wonderland
Gunma is best known for Kusatsu Onsen, one of Japan’s most famous hot spring towns, but the prefecture has far more to offer than a single headline destination. In fact, Gunma has one of the highest concentrations of onsen towns in the country, many of them with long histories, distinct water qualities, and atmospheres that feel refreshingly untouched by mass tourism.
Hakone is easier — closer to Tokyo, better known, more polished. But Gunma is what onsen culture actually feels like when it isn’t catering to day-trippers. The towns are quieter, the ryokans less performative, and the variety of spring waters — acidic, sulfurous, iron-rich, alkaline — gives you real reasons to move between towns rather than settling for whatever’s nearest the station.
After all, onsen are meant to be about rest, recovery, and slowing down, not jostling with tour groups or rushing to catch the last train back to Tokyo.
Gunma delivers:
- Better value across accommodation and meals
- Far fewer crowds, even in peak seasons
- A remarkable diversity of hot spring waters, all within a compact region
You’ll find everything from casual, family-run inns to deeply traditional ryokans—Japanese-style inns where tatami rooms, seasonal kaiseki meals, and thoughtfully designed baths are part of the experience. The variety of spring types is equally impressive, including acidic, alkaline, sulfurous, and iron-rich waters, each believed to offer different health benefits.

Notable Onsen Towns in Gunma
Minakami Onsen
A rare blend of hot springs and outdoor adventure
Minakami sits at the northern edge of Gunma, where mountains, rivers, and deep valleys shape the landscape. What sets Minakami apart is its seasonal versatility. In warmer months, the region is one of Japan’s top destinations for white-water rafting, hiking, and canyoning. Come winter, it transforms into a snowy playground with skiing, snowshoeing, and quiet riverside baths steaming in the cold air.
Onsen here are often set along the river or tucked into forested hills, making Minakami ideal for travelers who want to pair physical activity with deep relaxation. It’s a place where you earn your soak—and enjoy it all the more for it.
Shima Onsen
Atmosphere, history, and a sense of stepping back in time
Shima Onsen is a quiet, atmospheric town hidden deep in a narrow valley, reached by winding roads that feel deliberately removed from modern Japan. The effort it takes to get here is part of its charm.
The town is best known for its historic ryokans, including Sekizankan dating back to the 17th century that is often cited as an inspiration for the movie “Spirited Away.” Whether or not the connection is literal, the resemblance is unmistakable: wooden buildings, lantern-lit corridors, and baths that seem suspended in time.
Shima is ideal for travelers seeking stillness and nostalgia—a place where evenings are quiet, days revolve around bathing and walking, and the real world feels very far away.
Ikaho Onsen
Golden waters and classic onsen-town charm
Ikaho is instantly recognizable for its long stone staircase, lined with small shops, cafés, and ryokans. The town’s signature feature is its golden-brown onsen water, rich in iron, which gives both the baths and the town a distinct identity.
Ikaho is particularly well-suited to slow wandering—slipping on a yukata, strolling the steps, stopping for sweets or souvenirs, and soaking in multiple baths over the course of a day. It strikes a pleasant balance between atmosphere and accessibility.
Nearby Shibukawa adds a cultural footnote for manga fans as the setting for Initial D, making Ikaho an appealing stop for travelers who enjoy subtle pop-culture connections alongside traditional experiences.
Kusatsu Onsen
Powerful waters and one of Japan’s great onsen spectacles
Kusatsu is, quite simply, one of Japan’s most iconic onsen towns. At its heart lies the dramatic Yubatake—a steaming hot water field where vast volumes of spring water emerge naturally from the ground.
Kusatsu’s waters are among the most acidic in Japan, prized for their antibacterial properties and long believed to benefit skin conditions and overall health. The town’s bathing culture is unapologetically intense: hot, mineral-rich, and deeply traditional.
Despite its fame, Kusatsu retains a strong local identity, especially in the evenings once day-trippers depart. Staying overnight allows visitors to experience the town at its best—quiet streets, rising steam, and baths that feel almost elemental.
Kusatsu is the one I hesitated to include. It’s Gunma’s most famous town, covered everywhere, and busy enough by midday that the Yubatake can feel like a stage set. But the overnight experience is a different proposition entirely — once the tour coaches empty out and the steam thickens in the cold air, something in the town’s character reasserts itself. The case for staying, not day-tripping, is strong enough to warrant its place here.
2. Niigata: Sake, Seafood, and Exceptional Craftsmanship
Niigata surprised me. I went for the sake and left thinking mostly about the rice — which tells you something about how seriously this prefecture takes its food. It’s the home of Koshihikari, one of Japan’s most prized rice variety, and the same cold winters and snowmelt water that make it exceptional also make Niigata the country’s most prolific sake region. Add seafood from the Sea of Japan, and a metalworking district in Tsubame-Sanjo that produces the knives serious cooks worldwide actively seek out, and you have a prefecture that underpins a lot of what Japan is famous for — while receiving almost none of the credit.

Why Visit Niigata?
Rice Culture: The Foundation of Japanese Cuisine
The connection between rice and sake here isn’t incidental — it’s structural. Niigata’s winters are long and heavy with snow; the meltwater is exceptionally pure; the growing conditions produce Koshihikari with a glossiness and subtle sweetness that top chefs across Japan seek out for their sushi counters and kaiseki kitchens.
That same water, applied to brewing, yields what the Japanese describe as tanrei karakuchi — clean, dry, refined. Niigata has more sake breweries than almost any other prefecture, and the regional style pairs so naturally with local seafood that tasting them together starts to feel less like a food experience and more like an argument about geography.
If you want to understand Japanese food at a foundational level, Niigata is the classroom.
Seafood: Quietly exceptional and remarkably affordable
The sushi here is outstanding, and the prices are a quiet shock after Tokyo. A sit-down lunch for two at a good local restaurant typically comes to ¥2,000–4,000; an evening omakase runs ¥9,000–25,000 per person. For reference, comparable quality in Tokyo costs considerably more and often requires a reservation weeks in advance.
What makes it work is the combination: world-class rice, fish pulled from the Sea of Japan where warm and cold currents meet, and a food culture built around freshness rather than prestige. Niigata’s sushi doesn’t perform. The best version of it here isn’t an event — it’s just lunch.
The best approach is to start at a neighbourhood kaiten-zushi counter for lunch (you’ll eat well for around ¥2,000) and, if you’re staying overnight, book an omakase counter for the evening. The gap in price between the two is much smaller than the gap in Tokyo would lead you to expect.
Craftsmanship: Tsubame–Sanjo, the True Heart of “Made in Japan”
The phrase “Made in Japan” carries enormous weight worldwide, especially when it comes to knives, tools, and kitchenware. Many travelers buy Japanese knives in Tokyo—but few realize that the true center of Japanese metalworking craftsmanship lies in Niigata, in the twin towns of Tsubame and Sanjo.
Tsubame–Sanjo has been a hub of blacksmithing and metalwork since the Edo period. What began as nail-making evolved over centuries into a culture of precision, durability, and innovation. Today, the area produces:
- Professional-grade kitchen knives
- High-end cookware and tableware
- Industrial tools used globally
- Beautifully designed everyday objects
You can visit open factories, watch artisans at work, take part in hands-on workshops, and shop directly from makers—often at prices far below retail elsewhere. For anyone interested in Japanese craft, design, or functional beauty, Tsubame–Sanjo isn’t just a shopping stop—it’s a pilgrimage.
3. Nagano: Japan’s Natural Heartland
Nagano sits at the geographical and cultural heart of Honshu and is the third-largest prefecture on Japan’s main island. Mountainous and deeply forested, it is a destination where thoughtful route planning is essential—not because travel is difficult, but because distances are real, and each valley feels like its own world.
Among international visitors, Nagano is best known for skiing, particularly in Hakuba, whose alpine resorts gained global attention during the 1998 Winter Olympics. But reducing Nagano to snow sports misses its real character. This is a prefecture defined by mountains, pilgrimage routes, preserved towns, and wildlife, offering some of the most rewarding slow travel experiences in Japan.
For travelers drawn to nature and culture in equal measure, Nagano’s appeal lies in its diversity:
- Alpine landscapes rivaling the European Alps
- Some of Japan’s most important Buddhist and Shinto sites
- Well-preserved post towns from the Edo period
- Accessible wildlife encounters in natural settings
Because of its size, Nagano works best when explored through regional bases. The two most useful for international visitors are Nagano City — the better base for temples, and the snow monkeys — and Matsumoto, which gives access to the black castle, Kamikōchi, and the preserved Edo post towns along the Nakasendō. The two cities are 50 minutes apart by train; if you have three or more nights, they can be combined.

Key Areas to Explore
Shrines and Wildlife (Nagano City Base)
Nagano City is the capital of the prefecture and an excellent first stop for exploring its religious and natural heritage. At its center is Zenkōji Temple, one of Japan’s most important Buddhist sites and a pilgrimage destination for over 1,400 years. Unlike many temples, Zenkōji is open to all sects, and its atmosphere feels deeply communal rather than ceremonial.
From Nagano City, head into the surrounding forests to explore the Togakushi Shrine complex. Set along a mountain pilgrimage route, Togakushi consists of multiple shrines connected by woodland paths, including an unforgettable avenue of towering cedar trees. The journey between shrines is as meaningful as the destinations themselves, blending spirituality with nature.
In winter, Nagano City also serves as the ideal base for a day trip to Jigokudani Snow Monkey Park. Seeing wild Japanese macaques soaking in hot springs against a snowy backdrop is one of those experiences that feels uniquely Japanese—memorable not just for the spectacle, but for how naturally it fits into the landscape.
Nature and History (Matsumoto Base)
Matsumoto offers a different lens on Nagano, combining dramatic alpine scenery with beautifully preserved history. The city is anchored by Matsumoto Castle, one of Japan’s five National Treasure castles and among the country’s oldest surviving keeps. Its striking black exterior and original wooden interiors provide a rare, unfiltered glimpse into feudal Japan.
From Matsumoto, travelers can easily access Kamikōchi, one of Japan’s most celebrated alpine valleys. With crystal-clear rivers, dramatic peaks, and well-maintained walking trails, Kamikōchi offers some of the most accessible high-mountain scenery in the country. It’s equally rewarding for casual walkers and serious hikers.
Another rewarding excursion is Narai-juku, a beautifully preserved post town along the historic Nakasendō route. Once a key stop for travelers moving between Kyoto and Edo (modern day Tokyo), Narai retains its wooden townhouses, narrow streets, and slow rhythm, offering a vivid sense of life in the Edo period.
Choosing the Right Side Trip from Tokyo
The three destinations serve different kinds of trips, and it’s worth being clear about what you’re actually after before you decide.
If what you’re after is rest — a genuine slowdown rather than more sightseeing in a different prefecture — Gunma is the answer. It’s the closest of the three to Tokyo, easy to do in two nights, and the onsen towns are designed around exactly that kind of visit. If you’ve already done Hakone and found it too busy or too transactional, Gunma is what Hakone was supposed to feel like.
If food is the reason you travel, go to Niigata. The sushi rivals Tokyo at a fraction of the cost. The sake is the best in Japan by most serious measures. And Tsubame-Sanjo, which is the metalworking district thirty minutes south of the city, is where the knives serious cooks worldwide actually come from.
If you want mountains, temples, wildlife, and the kind of depth that makes a trip feel like it covered real ground, Nagano is the one. It’s also the most demanding to plan because the prefecture is large and each valley operates as its own world. The dedicated itineraries linked below will help, but budget at least three nights, and decide early whether Nagano City or Matsumoto is the better base for what you’re after.
Together, they offer some of the most rewarding alternatives to the Golden Route—ideal for travelers seeking nature, regional food culture, and slow travel. These are places that favor depth over speed, immersion over checklist itineraries, and moments that stay with you long after the journey ends.
