Toshiko Eguchi pays her respects to her late husband under a cherry tree, instead of kneeling before a gravestone.

The ashes of her husband, who died in November 2012, were placed under the tree as a form of natural burial known as "jumokuso" (burial under a tree). The tree is one of several planted in a jumokuso area in a cemetery in Machida, Tokyo.

Eguchi, 67, plans to have her own ashes buried under the same tree.
