Story

For thousands of years, Aso has been shaped by the interplay of volcanic forces and human hands.

Step into Aso’s open country and encounter something primal:
the land at its most elemental.

Sunlight cleanses the earth. Black soil drinks the rain.
Tender green shoots unfurl.

Pause within that cycle.
The senses awaken. You return to yourself.

Here, you step into an endless story still being woven between the land and its people.

A Day at HONO

Prologue

A little distance from your everyday self.

Arrive in Aso and breathe deeply.
The journey begins with the plants. As you walk the garden, a childhood absorption returns.

Foraging
Aso

A taste of Aso.

Grind the plants you have gathered into a wild tea.
With a cup you brewed yourself, welcome the nature of Aso into your body.

Spring
Water

Drawing water from the earth.

Reach into clear spring water and drink.
Touch the everyday life of a village of water.

Onsen

Scent, hot water and mountains

Oguni cedar you have shaved yourself, paired with wild plants, joins you in the bath. Gazing at the mountains of Aso, surrender to scent and water.

Primitive
Gastronomy

Gather around the fire and taste the earth.

As dusk falls, a fire is lit in the garden and dinner begins.
The scent of plants, the power of fire. Elemental flavors awaken the senses.

Nightfall

Listening to the voices of the wild.

Dim the lights and the mountain night draws near.
Listen to the voices in the grass, and become one of its presences.

Morning
Light

Waking with the earth.

Mornings when the grass glows in the sunrise.
Mornings of sea of clouds, mornings of rain.
No two are the same, and in each
you learn the rhythm of the earth.

Into
Aso

Into the fields of Aso.

The plants, the food, the people of Aso you met at the hotel.
Now visit the Aso that lies beyond, carrying your newfound curiosity.

Restaurant

Aso Primitive
Gastronomy

Follow life back to the sea.
Spring water rises in Aso, gathers into rivers and flows on to the waters of Kumamoto.

Following the path of this water, restaurant ASATO (阿然人) brings to the table the cycle this land has long held dear.

The crackle of firewood, the scent of straw,
the energy of nature, carried directly into each dish.

Cutting, grilling, smoking: elemental acts
that carry the memory of fire and wind,
and of a way of eating the modern world has almost forgotten.

In-Room SPA

CONTINUUM

Spa

A private retreat in your room.

Midway through the journey, quietly restore body and mind.
Held by the nature of Aso, breathe deeply
and return to your inner self.
