Gunma's mountainous landscape means the weather can vary greatly from one area to another. The hottest months are July to September, and the coldest are December to March.

In its flatter, urban areas like Takasaki and Maebashi, the average winter temperatures are around 5 degrees Celsius while summer temperatures average around 26 degrees. Temperatures can exceed 35 degrees on some days. These areas are prone to strong northerly winds in winter.

In Gunma’s more mountainous north, summers are cooler and winters are colder, with heavy snow.


There are very few money exchanges in Gunma, so it’s best to change your foreign currency before you arrive. There are ATMs in most of Gunma’s main destinations, but it’s advisable to withdraw enough cash before you arrive at an onsen or ski resort. Most facilities take credit cards and many take QR code payments, but it’s not uncommon in Japan to find stores and restaurants that only take cash, so don’t rely solely on a card for your stay.


Most of Gunma’s hotels and ryokan offer free Wi-Fi. There are a few Wi-Fi hotspots around Gunma’s main destinations but to be sure you can stay connected—particularly in more rural areas—buy a prepaid SIM card or rent a pocket Wi-Fi unit upon arriving in Japan.

Left Baggage
