Lake Okotanpe is a small lake with circumference of 5 km, located in the west of Chitose City, Hokkaido. It is a dammed lake created by lava that blocked the Okotanpe River, which flows out of this lake into Lake Shikotsu. The lake is located in a relatively high land with an altitude of the lake surface of 574 m. The lake is surrounded by the primary forest of Jezo spruce and Sakhalin fir, which create serene hush. Lake Okotanpe, together with Lake Shinonome and Lake Onneto, is counted as one of the 3 mysterious lakes in Hokkaido. The hue of the lake surface varies delicately with seasons or weather. As the lake itself and the surrounding area are designated as a special protection area, visitors cannot go down to the lakeside. However, the lake seen from the nearby observation tower is an exquisite view. If you look down at the mysterious change in color from cobalt blue to emerald green on the surface of the lake, which is surrounded by the huge primary forest spreading at the foot of grand Mt. Eniwa, you will be convinced it’s a really mysterious lake. You can enjoy marvelous changes in nature.

The word for wrapping in Japanese is 'tsutsumu' and has the kanji character '包', which is derived from a Chinese pictogram of a pregnant woman with a baby inside her. Therefore, the word 'tsutsumu' carries the sense of tender motherhood.

In Japan, tsutsumu will remind you of furoshiki, the cloth for wrapping things. One furoshiki cloth can freely be used to wrap many things of varying shapes. It gives a feeling of flexible softness and tenderness.

包 can also be read as 'kurumu'. You could say 'be tsutsumu-ed in a fog' but never 'be kurumu-ed in a fog'. The word 'kurumu' is used mainly in the sense of 'wrapping your belongings'. Kurumu also means 'wrapping like rolling' and is matched with furoshiki and other cloths.

Following Japanese tradition, you can carry and give a gift 'tsutsumu-ed' in wrapping paper and 'kurumu-ed' in furoshiki; such a gift would be wrapped in double tenderness.
