The weather in Osaka is almost the same as other major cities in Honshu such as Tokyo. In September, the hot summer is over and the cool days are gradually increasing. In early September, there are days when the maximum temperature is about 35 degrees, but it will become cooler in mid September. In late September it will be cooler and more people will wear long-sleeved shirts.

I used to live in Osaka before. It was too hot in August, so I did not like going to the city center. However, it will be much easier to spend in September, and there are memories that I went to play at Osaka Castle Park as well.

In September, Japanese children finish their summer vacation and school begins. So, on weekdays the sights are relatively vacant.

However, in September many typhoons come to Japan every year. Typhoons may also hit Osaka. When a typhoon comes, you can not walk because wind is strong. Trains and planes will of course not work.

Even if you come to Osaka at that time, you probably will not be fun. So please make sure the weather forecast whether typhoons will come before you come to Japan. Even after coming to Japan, please get the latest weather forecast. If you are likely to be affected by the typhoon, I would recommend changing your itinerary.

Below is the meteorological data of Osaka in September released by Japan Meteorological Agency. please refer.
