Hey, just dropping a line to say thanks for the help with all the info! We just went on a drive trip at Hokkaido 2 weeks. Its not the best time to be but low seasons are great too!
Btw, one tip for all travellers in Hokkaido – zap up all those brochures etc u see at car rentals, tourist information. They all have good discount codes for rides, attractions, and restaurants. Despite not reading Jap, we made good use of those discounts. So keep an eye out for them!
Driving was really a torture keeping at mostly 50-80km /hr. But generally a breeze. Everyone should go to super 5 floor Daiso store in Sapporo, walking distance from Mercure. You’d go mad shopping haha!
