Big Cedar is a tree in Small-Cedar district, and is near the village of Sakegawa, in Mogami County, Yamagata prefecture.

Although the great cedar tree might look like a couple of trees, it is in fact a single tree standing among paddy fields. Its base is 6.3m in circumference and it is 20m tall. It is said to be more than 1000 years old.

Because it has two big trunks, it is also called the 'Couple Cedar' or 'Marriage-Tie Cedar'. In addition, owing to its resemblance to a tree seen in the movie, 'Tonari-no-Totoro', it has lately gained more fame and come to be called 'Totoro's tree'.

The tree is venerated by the village and a mountain deity has been enshrined at its base.

Usually, a cedar tree tends to grow narrow and high in order to get more sunshine and survive. But, because there has been nothing other than rice fields around the tree, it has leisurely spread out to receive much sunshine.
