The city of Inazawa experiences a distinct seasonality in its rainfall distribution throughout the year. The climate is characterized by a humid and rainy summer period and a significantly drier winter. This creates two clear seasons to consider when planning your trip.

The wettest period occurs during the summer months. The peak of the rainy season arrives in July, which is the absolute leader in both rainfall (10 mm) and frequency, with an average of 21 rainy days. June and August also feature high humidity, with 16 and 20 days of precipitation respectively. During this time, rain is frequent, which is typical for the summer monsoon climate in Japan.

In contrast, winter is the driest time of year. The lowest amount of precipitation falls in January and December (only 2 mm each). February and November are also quite dry, with 3 mm of rainfall. Although rain is rare during these months (about 8–9 days per month), low temperatures—especially in January when the thermometer can drop to 0.4°C—create the possibility of light snow or cold rain.

When planning a trip to Inazawa, it's important to choose your wardrobe carefully, as the weather is highly seasonal. The key principle is layering. This will allow you to stay comfortable throughout the day as temperatures change and when moving between the outdoors and air-conditioned spaces.

Spring (March–May) and autumn (September–November) are the most comfortable seasons to visit. The weather during these times is mild but changeable. An ideal solution is to bring items that are easy to combine: T-shirts, long-sleeves, a light sweater or fleece, as well as a windbreaker or a mid-season jacket. Although there is less precipitation in these months than in summer, a compact umbrella may still come in handy, especially in spring when there can be more rainy days.
