A little late review, wore it on vacation for 2 weeks in Japan during April, went to Osaka, Kyoto, Nara, Tokyo, and Mount Fuji, here's my honest opinion.
The hoodie does great from temperatures 12°c up to 24°c in city/town areas. Anything lower than 10°c is where the hoodie starts to struggle, and above 25°c would be too hot to continue wearing the hoodie.
Overall, the hoodie does a good job at keeping you warm within the temperatures previously stated, fleece is quite comfortable along with having a generous amount of pockets.
One thing to note is that the jacket is using US sizing, get one size smaller from what you usually wear as there might be a difference. I usually wear S or M clothing but the hoodie's XS size fits me just right, make sure to refer to the sizing chart for reference.
