The JR Joetsu and Hokuriku Shinkansen lines connect Takasaki to Tokyo (about 50 minutes) and beyond. Local JR and private railway lines (like Joshin Railway) serve major towns. Buses are essential for reaching onsen towns and remote areas; consider bus passes for tourists. Renting a car is highly recommended for exploring mountainous regions and rural attractions; major rental agencies are at Takasaki and Maebashi stations. Taxis are available but expensive. Popular navigation apps include Google Maps, Japan Travel by Navitime, and Yahoo! Japan Transit.
April to May for pleasant spring weather and cherry blossoms; October to November for stunning autumn foliage in the mountains. December to March for skiing and snowboarding, with peak conditions in January-February. July-August is hot and humid but ideal for mountain escapes and festivals like the Tanabata celebrations. Avoid late June to early July (rainy season) for outdoor activities.
Remove shoes before entering homes, ryokan, and some traditional restaurants. When using onsen, wash thoroughly before entering the bath, and do not wear swimsuits; tattoos may be prohibited at some facilities. Tipping is not customary; excellent service is expected. Be polite and quiet in public spaces. When visiting shrines or temples, follow purification rituals. Try local specialties like yakimanju (grilled buns) and konnyaku (konjac) dishes. Gift-giving is appreciated when visiting someone's home.
Gunma is extremely safe with low crime rates. Exercise normal precautions in cities like Maebashi and Takasaki. When hiking or engaging in adventure sports in areas like Minakami or the Japanese Alps, check weather conditions, use proper gear, and consider guided tours for risky activities. Be aware of volcanic activity warnings around Mount Asama. Road conditions in mountainous regions can be challenging in winter; use winter tires or chains. No specific areas to avoid, but be respectful of private property in rural locales. Scams targeting tourists are very rare.
Gunma has excellent medical facilities, including Gunma University Hospital in Maebashi and Takasaki General Medical Center. No specific vaccinations are required beyond routine travel vaccines. Tap water is safe to drink. Be cautious when using onsen if you have high blood pressure, heart conditions, or are pregnant; follow posted guidelines. In rural mountainous areas, medical facilities may be limited, so carry necessary medications. Tick-borne diseases like Japanese Spotted Fever are rare but possible in forested areas; use insect repellent. Travel insurance is recommended.
