Fly to Hokkaido

After a long interval, I rode on plane. The plane flied from Hiroshima to Sapporo.
I planed to fly to Island Rishiri in Hokkaido after I reached to Sapporo.
But, e-mail information said that plane to Rishiri may not to fly because of bad seeing by the mist.
So, I considered about the plan changing in the plane.
