Unable to Identify Destination
The designation '20, Japan (state)' does not match a recognized Japanese prefecture, city, or administrative region in our editorial records. Japan has 47 prefectures, each with a proper name — for example, Tokyo, Osaka, Kyoto, Hokkaido, Okinawa, or Nagano (which happens to be numbered Prefecture 20 in Japan's official prefecture code system).
If you intended Nagano Prefecture (prefecture code 20): Nagano is a landlocked mountain prefecture in central Honshu, known for the Japanese Alps, the 1998 Winter Olympics host city of Nagano, Matsumoto Castle, and Kamikochi valley. It is one of Japan's premier destinations for hiking, skiing, onsen, and cultural heritage.
Please verify the intended destination and resubmit for a complete, accurate guide. TravelerPulse is committed to providing only verified, factual travel information and will not fabricate details for an ambiguous location.
If Nagano Prefecture was indeed the intended destination, the sections below provide a general outline based on widely known information about that prefecture.
Before You Go
Visas
Japan has specific visa requirements that vary by nationality and purpose of visit. For current, authoritative requirements, visit TravelerPulse's Visas section and the official website of the Japanese Ministry of Foreign Affairs or your nearest Japanese embassy or consulate. Do not rely on secondhand sources for visa information.
Health
No routine vaccinations are specifically required for travel to Japan beyond standard travel health precautions. Consult a travel health clinic or your physician before departure. Tap water is safe to drink throughout Japan.
Travel Insurance
Medical costs in Japan can be high for uninsured visitors. Comprehensive travel insurance including medical evacuation coverage is strongly recommended.
Getting There
Assuming Nagano Prefecture
Nagano Prefecture has no commercial airport. Most visitors arrive via Tokyo (served by Narita International Airport and Haneda Airport) or Osaka (Kansai International Airport) and continue by land.
Shinkansen
The Hokuriku Shinkansen (formerly the Nagano Shinkansen line) connects Tokyo's Shinjuku area to Nagano city in approximately 80–90 minutes. This is the most convenient option for most international visitors. Verify current schedules and fares on the JR East website or a reputable booking platform.
Highway Bus
Long-distance highway buses connect Nagano city and other points in the prefecture to Tokyo, Osaka, Nagoya, and other major cities. Journey times are longer than the shinkansen but fares are generally lower. Verify schedules and booking options locally or through established bus operators.
Getting Around
Within Nagano Prefecture
Nagano Prefecture is large and mountainous. Local trains operated by JR East and private lines (including Alpico Transport and Shinano Railway) connect major towns, but service to rural and alpine areas can be infrequent.
Buses
Buses are essential for reaching destinations such as Kamikochi, Zenkoji temple area, and ski resorts. Many seasonal routes operate only during specific months — verify schedules before traveling, as some mountain roads and bus lines are closed in winter or during off-season periods.
Car Rental
Renting a car gives the most flexibility for exploring the prefecture, particularly outside the main towns. An International Driving Permit (IDP) based on the Geneva Convention is required for foreign license holders. Road conditions in mountain areas can be challenging in winter — confirm seasonal road closures before driving.
IC Cards
Suica and Pasmo IC cards work on JR lines and some local services in the prefecture. Confirm acceptance on specific routes before relying on them.
Things to See & Do
Natural Landscapes
- Kamikochi: A high alpine valley in the Northern Japan Alps, accessible only by bus or foot (private vehicles are prohibited). Open seasonally — typically mid-April to mid-November; verify exact dates each year.
- Jigokudani Monkey Park: Famous for wild Japanese macaques (snow monkeys) bathing in natural hot spring pools. Located near Yamanouchi town.

- Narai-juku: A well-preserved post town on the old Nakasendo highway, offering a glimpse of Edo-period merchant culture.
Winter Sports
Nagano hosted the 1998 Winter Olympics. Several internationally recognized ski resorts operate in the prefecture, including areas around Hakuba, Shiga Kogen, and Nozawa Onsen. Verify resort operating seasons and lift status before booking.
Food & Drink
Regional Specialties
Nagano Prefecture has a distinct food culture shaped by its mountainous, landlocked geography and long winters.

Money
Japan remains heavily cash-based outside of major cities. ATMs at Japan Post offices and 7-Eleven convenience stores reliably accept international cards; availability of card payments at smaller establishments and rural areas is limited. Carry sufficient yen when traveling outside Nagano city.
Connectivity
Pocket Wi-Fi rental and data SIM cards are widely available at major airports. Coverage in deep mountain areas may be limited.
Medical Facilities
Nagano city has hospitals with general facilities. Rural and mountain areas have limited medical services. Travel insurance with evacuation coverage is important given the remote terrain in parts of the prefecture.
Safety
General Safety
Nagano Prefecture is generally safe for travelers. Standard precautions apply: be aware of your surroundings and secure your belongings, though petty crime rates are low by international standards.
Natural Hazards
The prefecture sits in a seismically active zone. Familiarize yourself with basic earthquake procedures. Several active and semi-active volcanoes are present in the broader region; check current volcanic activity alerts from the Japan Meteorological Agency before hiking in volcanic areas.
Mountain Safety
The Japanese Alps present genuine alpine hazards including sudden weather changes, extreme cold, and difficult terrain. Do not hike high-altitude routes without appropriate gear, fitness, and up-to-date local conditions information. Register your hiking plan (tozan todoke) at local police stations or trailheads as required.
Winter Driving
Mountain roads can be icy and snowbound in winter. Use vehicles equipped with winter tires or chains. Check road closure information before setting out.
Local Culture & Etiquette
General Etiquette in Japan
Standard Japanese cultural norms apply throughout Nagano Prefecture. Remove shoes when entering traditional accommodations (ryokan), temples, and many private homes — look for entry areas (genkan) and shoe racks as cues.
Speaking quietly in public spaces, particularly on trains, is the norm. Many signs in tourist areas are available in English, Chinese, and Korean, though English proficiency among the general population in rural areas may be limited; a basic phrasebook or translation app is useful.
Onsen Etiquette
Nagano has numerous onsen (hot spring baths). Standard onsen rules apply: wash thoroughly before entering the communal bath, remove all clothing (swimwear is generally not permitted in traditional onsen), and avoid submerging towels in the water. Many facilities do not admit guests with visible tattoos; verify policies in advance.
Temple and Shrine Visits
Respectful behavior at religious sites is expected. Follow posted instructions at individual sites regarding photography, areas open to visitors, and offerings.
