01 / A PLACE TO LEARN FROM
Longevity is
a whole-person question.
Okinawa became internationally known for exceptional longevity among its older generations. The blue-zone perspective invites attention to the patterns around a life: food, movement, belonging and purpose.
The picture continues to change. Younger generations do not automatically share the same health patterns. For Yotsuba, Okinawa is a place to learn from and a source of identified ingredients — a living context for everyday care.
02 / FIND THE STORY ON THE MAP
Many islands.
Distinct connections.
Follow the Ryukyu island chain south-west. Select a place to discover how research, landscape and ingredient origins connect.
Generalised geographic outlines. The map shows island locations, not a boundary of longevity or a sourcing area for every ingredient.
THE YAEYAMA ISLANDS
石垣島・八重山An island origin for cultivated microalgae.
Ishigaki is home to Yaeyama Chlorella production. The island's sunlight, climate and water support managed, land-based cultivation. Kabira Bay is part of the landscape; cultivation takes place in dedicated production facilities.

What we take
into everyday life.
Our four leaves of care offer a way to translate a broad island perspective into ordinary, repeatable habits.
An active everyday
Comfortable walks, strength, balance and movement woven into daily tasks.
A sustainable rhythm
Space for sleep, pauses and recovery, adapted to the person.
A life with others
Relationships, participation, purpose and the support of a community.
04 / OUR INGREDIENT CONNECTIONS
From land and water.
With a clear identity.
The island connection becomes meaningful when we can name the ingredient, its origin and its place within a complete formula.
THE LAND
The colour of a varied table.
Island vegetables, herbs and citrus connect everyday nourishment with the character of Okinawa. They bring variety, flavour and a distinct regional identity to the food story.
Okinawa Tropical Aojiru brings together a declared sixteen-vegetable blend, five-fruit blend, Peucedanum japonicum, Okinawan moringa and other measured components.

06 / A STORY THAT CONTINUES TO BE STUDIED
The questions
keep evolving.
Okinawa's longevity heritage is an active research and community conversation. Different organisations contribute different kinds of knowledge.
Okinawa Centenarian Study
A long-running programme studying diet, activity, genetics and psychosocial factors among older Okinawans. ORCLS continues research that began at the University of the Ryukyus.
Ageing, cognition & the microbiome
Researchers from the University of the Ryukyus, OIST and collaborators continue to examine healthy ageing. A 2026 study in older Ginowan residents explored associations between gut microbiota and cognitive function; it did not establish causation or test Yotsuba products.
A local conversation about living well
The Yomitan Blue Zone Research Council brings local culture, sustainable tourism and healthy life expectancy into community discussion. It is one example of how the island story is being explored today.
Research bodies are named for context. Blue-zone geography is not a product certification, and these studies do not demonstrate that a particular supplement extends life.
07 / OUR ISLAND PERSPECTIVE
Keep the origin clear.
Keep the person
at the centre.
Our Okinawa direction brings regional ingredients, contemporary preparation and whole-person care together. We express this connection through thoughtful formulas, clear ingredient stories and a continuing curiosity about the islands.
