AONAGI ISLAND · GLASS AND STONE
Find a stone. Learn its name. Bring it together with glass.
A quiet island to explore, guided by your own curiosity.
A DAY ON THE ISLAND
Search by the waves. Stop at the workshop.
Before you know it, the sun is setting.
FOLLOW YOUR CURIOSITY
A stone catches your eye. Your day begins.
Discovery leads to curiosity.
Curiosity leads to something you can make.

Walk the coast, forest, river and caves, looking for stones along the way.
Find something worth keeping—for reasons of your own.

Wash a stone, examine it and open the field guide.
What was once just a colour or a shape begins to have a name—and a story.


Bring stone and glass together to make a work of your own.
Display it in your gallery, or discover other creations at the sea museum. Finding a stone is only the beginning.
A PLACE FOR YOUR COLLECTION
A brick atelier. An old glasshouse. A little studio with peeling paint.
With every work you display, make your gallery a little more your own.

CURIOSITY, GROUNDED IN SCIENCE
“What kind of stone is this?”
A small question in a game can open a door to the real world. We want to meet that curiosity with care, staying as faithful as we can to the science of minerals and rocks.
We consult official mineral lists, scientific references and museum records for names, classification and properties. We check the sources and permissions for specimen photographs, too.
Aonagi’s geography, story and simplified collecting and making are part of a fictional world. We aim to distinguish those choices from the properties of real stones.
We do not want plausible stories to stand in for missing evidence. We revisit sources and correct mistakes. This is a world we keep learning about, not a claim to have every answer.
THERE IS NO NEED TO HURRY
Take a balloon ride. Sit by the fire. Dance.
There is more than one way to spend a day here.

As the balloon rises, the shore you just walked grows smaller below. Find your next detour from the sky.

Step onto the dance floor and move with the music. There is more to an island evening than looking for stones.

When the stars come out, take a seat by the fire. Let the discoveries of the day settle into a quiet island night.
YOUR TIME, YOUR TREASURES
You decide what to treasure.
Even on a day when you find nothing, the time spent here stays with you.
