a list of notable flower fields in Hokkaido ... I think for you Furano probably works best, however, I don't know if anything is going to be in bloom in mid october

not sure why you want to see pumpkin patches they are pretty unremarkable in my experience ... although in the US typically pumpkin patches are part of farmer's market/ food stand and they sometimes have attractions themed around Halloween so maybe something similar exists in Japan???, but the actual pumpkin patch is not particularly beautiful as the pumpkins grow basically on the ground and are typically covered by foliage and/ or mud.
