It’s safe. Per both the Japan Radiation Map and Safecast, radiation levels in Hokkaido are safe (green) at less than 0.05 microSieverts (μSv) per hour, or 1.2 μSv/day.
For comparison, if you live in a brick or concrete house you get a dose of about 70 μSv/year, and if you spend 14 hours on a plane, you will get a dose of around 100 μSv from atmospheric radiation.
