Advice and weather

Hello everyone,

I’ll be in Japan for 10 days from Oct23 to Nov 2, but I just checked the weather, (on AccuWeather only one showing this far) and it’s forecasted to rain most of the time. I know weather predictions aren’t always accurate, but it’s making me a bit anxious.

I could change my trip to Oct 30 to Nov 9 with almost no extra cost, as my tickets and hotel bookings are flexible.

Do you think it’s worth changing the dates, or should I stick with the original plan?

Thanks for your advice!
