Japan’s Real-Life Waterworld Mariner #Waterworld #SailingLife #OceanStories
Meet Mitsuharu Kume — the closest real-world equivalent I’ve ever found to Kevin Costner’s “Mariner” from Waterworld.
He may not have gills (that I know of), but he has everything else:
a life shaped by tides, storms, shipwrecks, deep dives, and a lifelong devotion to the ocean.
Mitsu is a fisherman, diver, sailor, photographer, conservationist, educator, and a father.
He began life as a marine civil engineer designing harbours in Tokyo…
but quickly realised he didn’t want to design the ocean — he wanted to live in it.
So he left the office, joined an offshore fishing boat, and never looked back.
During his years on Tanegashima he became deeply involved in sea turtle conservation and launched
Sea Turtle Crew, an NPO dedicated to protecting loggerhead turtles and teaching island children about the marine world they inherit.

Today, Mitsu is preparing a 33-foot Coura (a 1969 Ranger 33) to follow the turtles’ ancient route to Mexico.
🌊 Buren Bay — Our Harbour, Our Community
Buren Bay is more than the mooring point for my sailboat, Wahine.
It is my longevity laboratory, my home for reflection and writing…
and the home of Mitsu — the unofficial Commodore of our tiny, informal yacht harbour.
Living beside him has taught me more than any textbook, lecture, or seminar ever could.
He has helped me navigate treacherous weather, introduces me to the community,
and on stormy days when reaching my boat is “adventurous,” he offers me his guest room.
🌿 Lessons From Mitsu
Our conversations on the steps of his vintage seaside home drift from philosophy to nonsense,
from purpose to parenting, from seamanship to gratitude.
He reminds me to be brave.
To be kind.
To work hard.
To respect the sea.
And to stay rooted: in family, in community, in responsibility.
His 92-year-old mother — sharp, independent, living life on her own terms —
embodies the resilience I’ve spent two years studying on my journey across Japan.
We all need a Mitsu in our life —
someone who keeps us honest, grounded, and moving forward under full sail.

Wake Early. Move Early. A Pattern in Japan’s Longevity Hotspots
As I continue traveling through Japan’s longevity hotspots, I keep noticing recurring patterns. One of them is simple: Many of the people who age well tend to wake early—and get moving early. Movement woven naturally into the rhythm of daily life. ...
A Stone in Remote Japan that Explains How To Age Well
In a remote village near where my boat Wahine is moored in Amami, a weathered stone has long been part of a local coming-of-age ritual. At first glance, it seems ordinary. But the longer I study longevity and community in Japan, the more convinced I beco...
One of the Great Fears of Aging
The goal is not to stay young. It is to remain engaged with life. Curious. Connected. Active. Participating in the world around you. A small Field Note from island life in Japan. About me: I’m Lowell Sheppard, 71, sailor, author, and Fellow of the Roy...
Back to the boat . . . Then this Happened

Food, Friendship, Aging Well
Fresh food. Local people. Shared meals. The deeper I travel into Japan’s longevity hotspots, the more I suspect healthy aging is not just about what people eat—but who they eat with. This Field Note was filmed at a small local restaurant deep in the ...
