Hokkaido is the northernmost of Japan’s four main islands, separated from Honshu (the main island) by the Tsugaru Strait. It constitutes approximately 22% of Japan’s total land area but is home to only around 5.2 million people — roughly 4% of the national population. This disparity between space and population density is immediately apparent to visitors; Hokkaido feels spacious in a way that the rest of Japan rarely does.
Geography and Size
Hokkaido covers approximately 83,450 square kilometres, making it comparable in size to Austria or the island of Ireland. The interior is mountainous, with the Daisetsuzan range (including Hokkaido’s highest peak, Mt. Asahidake at 2,291m) dominating the central region. Coastal plains, particularly in the west and south, support the island’s substantial agricultural sector.
Distances within Hokkaido are significant and frequently underestimated by visitors accustomed to the compact geography of Honshu. Sapporo to Kushiro, for example, is approximately 300 kilometres — a journey of four hours by train or car. Planning itineraries that account for these distances is essential; our suggested itineraries are designed with realistic travel times.
Climate
Hokkaido has a subarctic to humid continental climate that differs markedly from the rest of Japan. It largely avoids the tsuyu (rainy season) that affects Honshu from June to July, and summers are notably cooler and less humid. Winters are long and cold, with heavy snowfall — Sapporo receives approximately five metres of cumulative snowfall annually.
| Season | Temperature Range | Conditions |
|---|---|---|
| Winter (Dec–Feb) | -5°C to -15°C (interior colder) | Heavy snow, cold, dry powder |
| Spring (Mar–May) | 0°C to 15°C | Snow melt, cherry blossoms in May |
| Summer (Jun–Aug) | 18°C to 26°C | Warm, low humidity, flowers |
| Autumn (Sep–Nov) | 5°C to 18°C | Foliage, harvest season, cooling |

Language
Japanese is the primary language throughout Hokkaido. English proficiency is generally lower than in Tokyo or Osaka, particularly outside Sapporo, Niseko, and major tourist areas. However, most tourist facilities, hotels, and transport systems provide English signage and basic English service. Translation applications (particularly Google Translate’s camera function for reading menus and signs) are highly practical tools for independent travel.
Currency and Payments
Japan uses the Japanese yen (¥). While credit card acceptance has expanded significantly in recent years, Hokkaido — especially smaller restaurants, rural ryokans, and market stalls — still operates substantially on cash. We recommend carrying ¥10,000–20,000 in cash at all times. 7-Eleven ATMs accept most international debit and credit cards and are widely available throughout the island.
Time Zone
Japan Standard Time (JST), UTC+9. Japan does not observe daylight saving time.
Electricity
100V, 50Hz. Outlets use Type A plugs (two flat pins, identical to North American standard). Most modern electronic devices (phones, laptops, cameras) accept 100–240V and will work without a converter, though a plug adapter may be needed for non-Type A plugs.
Internet and Connectivity
Prepaid data SIM cards and eSIMs are available at New Chitose Airport and in electronics stores throughout Sapporo. Pocket WiFi rental is another option, particularly for groups. Free WiFi is available at train stations, convenience stores, and many cafes, but having personal mobile data significantly simplifies navigation, translation, and travel logistics.
Entry Requirements
Citizens of most Western countries can enter Japan visa-free for stays of up to 90 days for tourism purposes. Visit Japan Web registration (an online customs and immigration form) should be completed before arrival to expedite the entry process. Requirements change periodically; we recommend checking current entry requirements with your country’s foreign affairs department before travel.
