Rainy Day in Nagano: Best Indoor Spots & Activities

Zenkoji (Okaidan Meguri)

A sacred place so deeply etched into the hearts of the Japanese that the saying "make a Zenkoji pilgrimage at least once in your life" was born. Beneath the national-treasure main hall, a mysterious experience that can never be tasted elsewhere awaits.

Okaidan Meguri is a ritual in which you walk forward through a jet-black corridor that continues directly beneath the inner sanctuary of the main hall—literally in "the darkness of zero." As you slowly proceed while feeling along the handrail, your sight is completely cut off, and sharpened senses and silence envelop your whole body. The moment you touch the "Lock of Paradise" partway along the corridor, a karmic bond with the principal image is said to be fulfilled, and that instant is sure to make your heart grow warm. The underground space, where even the sound of rain recedes, sinks into the heart all the more deeply precisely because it is a rainy day.

Inside the main hall the temperature and humidity are stable throughout the year, so a great appeal is that you can worship comfortably without a coat even in rain. After worship, while enjoying the lingering resonance of the Okaidan Meguri, the local way to enjoy it is to stop by long-established shops on the "Nakamise-dori" approach for buy-by-weight shichimi togarashi (seven-spice chili) and samples at Yawataya Isogoro.

Best Season and Recommended Time of Day: You can worship throughout the four seasons, but the early-morning hours of 6-7 a.m., when morning services (morning rituals) are held, are a hidden-gem time when there are few tourists and you can worship quietly in the crisp air. Weekday mornings are especially calm in terms of crowds.

Tips for Travelers

- The Okaidan Meguri is in complete darkness, so those uneasy about their footing should go at a comfortable pace.

- Photography is prohibited inside. Put your camera away and concentrate on experiencing it with all five senses.

- The crowd peak is 10 a.m. to 2 p.m. on weekends and holidays. On rainy days people gather indoors, so aiming for right after the gate opens is recommended.

Access: About a 5-minute walk from "Zenkojishita Station" on the Nagano Dentetsu line. From JR Nagano Station, a bus (about 10 minutes) or taxi (about 10 minutes) is convenient. It is also about a 25-minute walk from Nagano Station, and walking while enjoying the atmosphere of the approach is its own pleasure.

Matsumoto City Museum of Art

When you walk about 10 minutes out of Matsumoto Station, a giant sculpture with vivid polka-dot patterns suddenly appears before your eyes. Yayoi Kusama's representative work "Visionary Flowers"—an endless stream of people stop in their tracks at its overwhelming presence. This powerfully declares from outside the building that Matsumoto is the hometown of Yayoi Kusama, an artist Matsumoto proudly presents to the world.

Once you enter the museum, that intensity increases even more. The Yayoi Kusama collection is among the most substantial of public art museums in Japan. The "Infinity Net" paintings that seem to spread infinitely, and the spatial installations that gently derange the viewer's senses, give fresh surprise no matter how many times you visit. Furthermore, there are abundant works by Matsumoto-born calligrapher Shinzan Kamijo and regional artists with ties to Shinshu, so a deep viewing experience awaits that does not stop at Yayoi Kusama alone.

On a rainy day the outdoor sculpture garden does get wet, but inside the museum is in perfect condition for leisurely viewing. The museum shop is stocked with unique goods designed by Yayoi Kusama, ideal as a souvenir of your trip.

Best Season and Recommended Time of Day: The periods of special exhibitions (several times a year) are especially worth seeing. In the morning right after opening there are few people, and you can face the works at length.

Tips for Travelers

- The estimated time needed is 90-120 minutes. If you want to view slowly, entering from the morning is recommended.

- Closed every Monday (the following Tuesday if Monday is a holiday). Check the official site before visiting.

- Matsumoto Castle is within walking distance. An itinerary combining the museum and the castle is a standard course.

Access: About a 10-minute walk from JR Matsumoto Station. Since you just walk straight down the main street from in front of the station, even first-timers can reach it without getting lost.

Karuizawa Museum of Contemporary Art

When you think of Karuizawa, many people probably picture a green resort or a long-established shopping area. But this place has a spot where you can quietly experience world-class art. That is the Karuizawa Museum of Contemporary Art.

Among the contemporary art galleries scattered throughout Karuizawa, this museum stands out for both scale and the quality of its collection. Works by domestic and international contemporary artists are displayed freely in a spacious setting, letting you taste the joy of "facing the works at length"—a flavor a notch different from large urban art museums. A day when rain taps at the windows is, rather, the day you should come here. A luxurious time is born in which you can be alone with art in the silence.

It is recommended to build a rainy-day stroll of Karuizawa starting from the museum. After taking a break at the museum cafe, if you head to the arcade of Kyu-Karuizawa Ginza-dori, which can be enjoyed even in rain, or to the covered Shopping Plaza Karuizawa, the day will fill up in the blink of an eye.

Best Season and Recommended Time of Day: The fresh greenery of May-June and October, when the autumn foliage is beautiful, especially heighten the atmosphere of Karuizawa as a whole, and the compatibility with art appreciation is also excellent. On summer weekends tourists increase, so a weekday visit lets you enjoy it more calmly.

Tips for Travelers

- From Karuizawa Station, a taxi or bicycle is convenient. On rainy days use the taxi stand in front of the station.

- There are also many distinctive galleries near the museum. If you have time to spare, hopping between art spots is one way to enjoy it.

- In winter there is a possibility of snowfall and closures, so always check the operating status before visiting.

Access: About 5-10 minutes by car from "Karuizawa Station" on the JR Hokuriku Shinkansen. On foot it is about 20-25 minutes. In rainy weather, using a taxi is smooth.

Nagano Prefectural Museum of History

From the Jomon period to modern times—a journey tracing the grand flow of time that the land of Nagano has carved, all under a single roof. That is the experience awaiting you at the Nagano Prefectural Museum of History.

Among all, what captivates the eye is the replica exhibit of the national treasure "Jomon Venus." The genuine article, excavated in Chino City, is housed at the Togariishi Jomon Archaeological Museum, but here you can observe an elaborate replica up close at length. The form, into which an artisan some 5,000 years ago breathed life into clay, is astonishingly refined even seen by modern sensibilities, and it seems the emotion of "beauty" is conveyed across time. In the special exhibition room, exhibits delving deeply into themes unique to Nagano are held regularly, so there are new discoveries no matter how many times you visit.

The vast exhibition rooms are perfect for a rainy-day stay, with a structure that can be enjoyed by a wide range of generations from families to seniors. There are also many areas inside where photography is allowed, and a delightful point is that you can tour leisurely while taking commemorative photos.

Best Season and Recommended Time of Day: It can be enjoyed throughout the year, but the special-exhibition season from spring to early summer often has especially substantial content. In the morning there are few group visitors, and you can view the exhibits leisurely.

Tips for Travelers

- Visit the adjacent Mori Shogunzuka Kofun (outdoors) on a sunny day. On rainy days it is better to concentrate inside the history museum.

- The estimated time needed is 90-150 minutes. Even the permanent exhibition alone has considerable volume, so schedule with plenty of time.

- The admission fee is relatively reasonable. The high cost performance is also a delight for travelers.

Access: About a 15-minute walk from "Yashiro Station" on the Shinano Railway, or about 10 minutes by taxi from "Shinonoi Station" on the JR Shinonoi Line. It is about 30 minutes by car from central Nagano City.

Nozawa Onsen

In the deep mountains of Shinshu, there is a hot-spring culture nurtured over hundreds of years. That is Nozawa Onsen. In this village, also known as a ski resort, a unique culture in which mountain worship and daily life have melded still lives and breathes today, gently wrapping visiting travelers in a nostalgic yet warm air.

Within the village, 13 outdoor public baths (sotoyu) are scattered about, each carefully managed by residents called "yu-nakama" (bath companions). The outdoor baths can basically be used for free (some baths accept donations), and the moment of soaking shoulder to shoulder with locals is an encounter with real Japanese hot-spring culture that cannot be tasted at tourist sites. The water is rich with the scent of sulfur, with a softness that seems to melt into your skin the moment it touches. The moderate heat warms you to the core, gently loosening a body and heart soaked by rain.

A round of outdoor baths on a rainy day is, rather, recommended. Walking the stone-paved alleys while listening to the sound of rain, crossing from one bath to the next—that act itself becomes the essence of travel. After a bath, while browsing souvenir shops where you can sample nozawana pickles, take a casual stroll through the alleys of the hot-spring town.

Best Season and Recommended Time of Day: Winter (December-March), when you can enjoy a round of outdoor baths amid snowscapes, has the finest atmosphere. The fresh greenery of spring and the autumn foliage are also beautiful, and it can be enjoyed in all seasons. Many outdoor baths are open from early morning, and use first thing in the morning, when there are few people, is especially recommended.

Tips for Travelers

- The outdoor baths are places of local daily life. Refrain from loud voices and long soaks, and be mindful to bathe with good manners.

- Some baths are quite hot (Oyu in particular is very hot). Don't push yourself—dilute with water as you bathe.

- Always bring a towel and change of clothes. Most outdoor baths have no sales or rentals.

- In rainy weather the stone pavement becomes slippery, so we strongly recommend visiting in easy-to-walk shoes.

Access: About 30 minutes by bus from "Iiyama Station" on the Nagano Dentetsu line. Or about 50 minutes by local bus from "Iiyama Station" on the Joetsu Shinkansen. By private car, about 40 minutes from "Toyota-Iiyama IC" on the Joshin-etsu Expressway. Within the village, a round of outdoor baths on foot is the basic style.

Access Information

Nagano Prefecture is wide from north to south, and access methods differ greatly by area. Here are the key points for touring efficiently.

Zenkoji (Nagano City) About 10 minutes by bus from "Nagano Station" (JR / Nagano Dentetsu), or about a 25-minute walk. From "Zenkojishita Station" on the Nagano Dentetsu line it is closer, about a 5-minute walk, which is convenient for those who prefer the train.

Matsumoto City Museum of Art (Matsumoto City) JR Shino

• Access (can you get there without getting wet?): The Matsumoto City Museum of Art is about a 10-minute walk from JR Matsumoto Station, and the Karuizawa New Art Museum is within walking distance of Karuizawa Station, so both are close to the station and easy to reach on a rainy day.

Also, Kyu-Karuizawa Ginza Street and Karuizawa Prince Shopping Plaza consist mainly of open-air streets without roofs; they are not covered arcades where you can walk without getting wet. Umbrellas and suitcases cannot be brought inside the Karuizawa New Art Museum, so plan on leaving them at the entrance. For a round of the public bathhouses at Nozawa Onsen, the stone-paved streets become slippery, so shoes with good grip plus a towel and a change of clothes are essential.

* Nagano Prefecture stretches a long way from north to south, and Zenkoji Temple (Nagano City), the Matsumoto City Museum of Art (Matsumoto City), Karuizawa (Karuizawa Town) and Nozawa Onsen (Nozawaonsen Village) are all far apart from one another. Limiting yourself to two or three places a day is realistic.
