At a large cemetery in a Tokyo suburb, cherry trees grow in between rows of traditional gravestones. The trees themselves are also graves - a form of tree burial called "jumokuso" gaining popularity across Japan as more people express their wish to return to nature after they die. For 3 days during cherry blossom season, we meet people flocking to the cemetery to pay their respects, including a man on his weekly visit to the grave of his late wife, who stood by him through difficult times; 3 brothers who always visit their father's grave together around this time of the year; and a woman who talks to her late husband as she sips on a beer, as they used to enjoy doing together.
