Nagano and Karuizawa: A Private Guide to the Japanese Alps
Nagano and Karuizawa are both reachable from Tokyo in about 80 minutes by shinkansen (bullet train), making them a straightforward two- or three-night add-on to a Tokyo stay. The two towns serve different purposes: Nagano is the base for Jigokudani snow monkey park and Zenko-ji temple, while Karuizawa is an upmarket summer retreat with outlet shopping and forest walks. Rail covers both towns easily, but Jigokudani, Shiraito Falls and the highlands around Kamikochi need a car or a private driver.
Getting there: the shinkansen from Tokyo
Nagano Station sits at the northern end of the Hokuriku Shinkansen. Trains run from Tokyo Station and from Tokyo's Ueno Station, with the fastest services completing the trip in roughly 80 minutes. Journey times and frequencies change seasonally, so check current schedules with JR (Japan Railways) when you plan your dates.
Karuizawa Station is on the Hokuriku Shinkansen as well, roughly 60–70 minutes from Tokyo. It is a convenient stop on the way to or from Nagano if you are travelling onward, though the two towns are about an hour apart by car or by a combination of train and local bus rather than a direct train.
A JR Pass covers the shinkansen on these lines, but if this is a short add-on to a Tokyo trip, point-to-point tickets are often simpler. Check the current JR Pass rules and prices before you decide; the pass structure has been revised in recent years.
Jigokudani snow monkey park
The snow monkeys live at Jigokudani, in the mountains above Yudanaka and Shibu in northern Nagano Prefecture. The park is famous for the sight of Japanese macaques soaking in the steaming hot spring during winter. Two points are worth stating plainly:
- The monkeys bathe in the onsen mainly in the cold months, from roughly December to March. In summer the park is open and the monkeys are present, but they usually do not use the water.
- Reaching the park involves a walk of about 1.6 km (roughly one mile) each way along a forest path with steps and uneven ground. It is not a flat stroll. The path can be icy in winter.
Snowshoes or shoes with good grip help from December to March. The park opens early and closes before dark; hours shift by season.
Zenko-ji temple and Nagano city
Zenko-ji is one of Japan's most important Buddhist temples, founded in the 6th century and a destination for pilgrims for centuries. The main hall is unusual: visitors walk a pitch-black passage under the building to find a key representing enlightenment. The temple grounds hold several sub-temples, and the area around them has shops, ryokan and restaurants.
Nagano city itself is compact and easy to navigate. The station is modern and well signposted in English. The bus from Nagano Station to the snow monkey park (and to Yudanaka) is run by Nagaden; the journey takes about 50 minutes to Yudanaka, with a change for Jigokudani.
Yudanaka, Shibu and Nozawa onsen
The onsen towns south of Nagano are the natural place to stay if you want to visit the monkeys and end the day in a hot spring.
- **Yudanaka** is the largest of the three, with easy access from the station and a good range of ryokan.
- **Shibu** is smaller and quieter, and connects directly to Yudanaka on foot. Some ryokan in Shibu allow guests from other inns to use their baths at certain times.
- **Nozawa Onsen** sits higher up, about 30–40 minutes by bus from Nagano, and has 13 free public baths dotted around the village. It is a working ski resort in winter and a hot-spring village in summer.
Bathhouses in these towns are communal and typically require you to wash before entering the water. Tattoo policies vary by facility and ryokan; ask in advance if this matters to you.
Karuizawa: the summer retreat
Karuizawa has been a resort for well over a century, favoured by Japanese and foreign visitors seeking cooler air in summer. The main shopping street, Kyukaruizawa Ginza, runs for several hundred metres with cafes, clothing stores and food shops. The surrounding forest has walking paths, and cycling is popular on the quieter roads.
Shiraito Falls (Shiraito-taki) sits a short drive from the station. The falls are a wide, curtain-like sheet of water about 3 metres high and 70 metres wide, formed by groundwater seeping through the volcanic rock rather than by a river. It is a paved, easily accessible viewpoint, not a wilderness hike. Reaching it by public transport is awkward; a car or private driver is the practical option.
Matsumoto, Kamikochi and the ski season
Two extensions work well from this area:
- **Matsumoto** is about 45–50 minutes south of Nagano by limited express train. Matsumoto Castle is one of Japan's original keeps, with its distinctive black exterior, and the city has a good small museum scene.
- **Kamikochi** is a high valley in the Northern Alps, roughly 60–70 minutes by car from Matsumoto. Private cars are not allowed beyond the parking area at the valley entrance; you must continue by bus. The valley is open from mid-April to mid-November; it closes in winter.
For skiing, Nozawa Onsen and the larger resorts near Hakuba (about 70 minutes from Nagano) have reliable snow from December to March. Nagano hosted the 1998 Winter Olympics and the region's lifts and infrastructure reflect that. Rail covers Nagano and Karuizawa well; a car or private driver is the sensible choice for Jigokudani, Shiraito Falls, Kamikochi and anything in between the towns.
Frequently asked questions
How many nights do I need for Nagano and Karuizawa?
Two nights gives you Nagano city, Zenko-ji and a day at Jigokudani. Three nights adds Karuizawa comfortably, or time in Yudanaka or Nozawa onsen.
Do I need a JR Pass for this trip?
If you are based in Tokyo and taking a short return, point-to-point shinkansen tickets are usually simpler. Check the current JR Pass rules and prices before deciding.
When is the best time to see the snow monkeys?
The monkeys use the hot spring mainly from December to March, when the weather is coldest. The park is open year-round, but the monkeys rarely bathe in summer.
Is this trip doable without Japanese?
Nagano Station and the major buses have English signage, and restaurant menus in tourist areas often have English. Outside those areas, a guide or driver who speaks English makes a real difference.
Planning your trip
- **Confirm visa and entry rules before you book.** Rules for Japan change by nationality and by season; check with the Japanese embassy or consulate for your country, and with your airline, before committing to dates or non-refundable accommodation.
- **Book ryokan early for weekends and holidays.** Japanese holiday periods (New Year, Golden Week in late April–early May, Obon in mid-August) fill the onsen towns quickly.
- **Pack for the walk to Jigokudani.** The path is about 1.6 km each way with steps; in winter, ice and snow make proper footwear or snowshoes essential.
- **Decide early whether you need a car or private driver.** Rail covers Nagano, Karuizawa, Matsumoto and Nozawa well, but Jigokudani, Shiraito Falls and Kamikochi are all easier by road.
