However, recent events have highlighted the impact of natural hazards. Since August 2025, several regions in Japan have experienced heavy rainfall, leading to severe flooding and mudslides. This has affected essential services in certain prefectures, causing disruptions in transportation, power, water and food supply, telecommunications, and even emergency services and medical care. Travelers should monitor local news, heed local authority instructions, and be prepared for possible evacuation orders if visiting flood-prone areas, as recommended by the Government of Canada’s official travel advisories.
Typhoon season in Japan spans June through October, with September often seeing the highest frequency. These storms can rapidly intensify, especially affecting southern regions like Okinawa as well as coastal areas. All travelers during this period should allow flexibility in their plans, focus on weather forecasts from the Japan Meteorological Agency, and keep emergency contact information for airlines and tour operators. Even a passing typhoon can lead to widespread transportation cancellations and service interruptions. Outdoor activities or excursions to rural areas should be carefully considered, and indoor alternatives kept in mind on short notice.
Japan’s weather in September marks a transition from summer to autumn, with temperatures generally ranging from 20 to 29 degrees Celsius. Humidity is lower compared to midsummer, but localized showers and sudden weather changes are not uncommon. Hokkaido, in the north, begins showing autumn colors, making it a captivating destination for scenic travel. However, travelers should still pack for both warm and rainy conditions, as suggested in local travel guides and recent traveler reports on platforms like Odynovo Tours and the official Japan National Tourism Organization.
While Japan’s crime rates are low, there has been a slight increase in petty crime such as pickpocketing and purse snatching, particularly in entertainment districts. Visitors are cautioned to remain vigilant, avoid walking alone at night in less populated areas, and exercise general caution with valuables. New local regulations in response to overtourism have also been enacted in 2025: for example, specific alleys in Kyoto’s Gion district and certain viewing spots near Mount Fuji now have access restrictions, and fines are enforced for violations. Respect for local customs, especially regarding photography and personal space, is encouraged as local governments attempt to balance tourism with resident life.
Entry procedures for 2025 remain generally stable, but travelers should review Japan’s latest entry requirements, which are updated regularly at international airports. Transport systems remain efficient and safe, but to avoid confusion during possible delays—especially in the wake of storms or flooding—using navigation tools, avoiding rush hour, and having backup plans is recommended.
To summarize, travelers to Japan in September 2025 can expect stunning scenery and vibrant local festivals, but must stay informed about current weather risks, especially flooding and typhoons. Flexible planning, emergency awareness, and respect for local regulations are all essential for a safe and rewarding visit.
