PRIVATE BY NATURE
Time feels different when the place is yours alone
All 14 rooms and the spaces of Horizon Castle are reserved for one group.
Dining, conversation, and quiet moments by the sea can all be shaped around the purpose of the stay.
Every moment in this place, shared with those who matter most.
33° NORTH
More than rooms, the place itself becomes yours
Beside the 33rd Parallel North Observatory, across the bridge and further into the island, stands Horizon Castle.
The Goto-nada Sea and the horizon. Morning light. Passing clouds. Dusk. A sky filled with stars.
Exclusive use brings the rooms together with the sea, the sky, the light and the wind: the place itself.
CULTURE & AESTHETICS
Bring culture and aesthetics into the stay
At Horizon Castle, art, gardens, fragrance and music lend a quiet richness to every day of your stay.
Pause before a work of art. Attend to fragrance. Sense the space. Listen closely. Gather around the table and exchange thoughts.
SPACE · SPIRIT · SOUND · ART
Encounters with Japanese aesthetics can be incorporated into the stay according to its purpose.

DINING
Gather around one table
On a night when the whole property is yours, dining becomes one of the central moments of the stay.
Seafood and seasonal ingredients from Saikai. Watch the sea shift from evening into night as everyone gathers around the same table, with time for conversation.
With whom, where and how the table is shared: that time is part of the exclusive-use experience.
