Autumn
Autumn in Hokkaido is the season of the harvest. In Atsuma the rice fields turn gold before they are cut, and from the sea come hokki surf clams, which are at their best from autumn onwards.
Dinner at Mori no Auberge Mitsu is a Japanese creative course of seven omakase plates. There is no fixed menu: the course is built from what arrives that day, so the autumn menu is still being prepared.
Here are the ingredients of Atsuma you can expect to meet on an autumn stay.
Atsuma is farming country where rice growing runs deep. The town's branded rice, "Sakura-mai", is the Nanatsuboshi variety. At Mitsu this local rice is cooked in a clay pot, and in the steam that rises the moment the lid comes off, the air of Atsuma is there. Autumn is when the year's new crop comes in.
Atsuma sits close to the Pacific, and the Iburi area is rich in seafood. Neighbouring Tomakomai lands more hokki surf clams than any other municipality in Japan. The clams are said to be at their best from autumn into winter. At Mitsu, whatever arrives that day is served as sashimi or grilled.
The meat course uses Mailabuta, a branded pork raised in Atsuma, and Biratori beef from the neighbouring town. It is trimmed by hand from a large block, and the heat is adjusted so the meat keeps its freshness. At breakfast there is a rolled omelette made with free-range eggs. These three hold up the table at Mitsu whatever the season.
Where these ingredients come from is covered on the Ingredients of Atsuma page, and the shape of the course on the Dining page.

You can take in an autumn view on the way in or on the way out. Times below are rough drives from Mitsu.

In autumn the mountains around Lake Shikotsu turn red and yellow, and the colour is mirrored in the clear water. It is a fine lakeside drive at this time of year.

Atsuma is farming country, and its branded rice "Sakura-mai" is the Nanatsuboshi variety. In autumn the fields spread out in gold. New-crop rice and local produce are sold at Kobushi-no-yu Atsuma and elsewhere in town.

Autumn is when salmon run up the Chitose River. From the underwater viewing zone you may see them climbing the current at close range. It is the largest freshwater aquarium in Hokkaido.

At Yuni Garden in the town of Yuni, the kochia bushes turn red in autumn. The garden changes face with the season, from flowers to kochia. Please check the official site for opening dates.
Opening times and the weeks things are at their best are best checked with each site. The Around page covers all four seasons.
