I found it in Amami-oshima island.
Near the coast of Kasari-yoan town, my grandma, great-grandma, and great-great-grandma were born.
By the shore with dense screwpine trees, my grandma was making Shima-tofu.
On the way back with Michuki from the trip...
I told him the story that his mommy doesn't have her mother and father.
The same day, in the bathroom:

Michuki: Michuki's family are four, grandma, daddy and mommy.
Mom: You know your daddy's mother and father?
Michuki: Grandpa and grandma.
Mom: What about your mommy's mother and father?
Michuki: ...none (with a sad face).
Mom: Yeah...
Michuki: But, you have me. No worries!

Family is invaluable.
Amami people cherish human relationship.
I have the blood in my veins...

My grandmas were beautiful and tall...
85-year-old man told me so.
And also unbelievably cheerful ladies...

So great, Amami-oshima island!
