There is an annual Japanese holiday which remembers deceased ancestors. The actual date varies by region but usually falls between mid-July to mid-August. It is not an official holiday, rather a religious and traditional holiday which includes using lanterns to guide the dead, making food offerings to temples and celebrating with dancing.

Here is today’s humble haiku which recognizes this holiday, past and future, yet also celebrates the life still happening on this side of existence.
Our First O-bon
our day of the dead
has not yet arrived – still time
to explore this shore
