The Last Quiet Coastline In Okinawa — A Private Estate Reborn On Ishigaki

Property Highlights:
The site spans 2,051.57 sqm (approx. 620.59 tsubo) of freehold land — designated as residential and forest land — at an elevation of approximately 40 metres, with no use-district designation and no height or density restrictions typical of urban Japan. Frontage runs approximately 10 metres along a public road to the southwest. This is a scale of landholding that, on Ishigaki’s increasingly sought-after coastline, is no longer easy to secure.

The residence extends across 324.09 sqm (approx. 98.03 tsubo) in a two-storey reinforced concrete structure, originally completed September 2011 and undergoing a comprehensive renovation scheduled for completion in July 2026. Three bedrooms — including a tatami-floored third bedroom — are joined by a living and dining area of approximately 42.5 tatami mats (roughly 70 sqm), an infinity pool positioned to draw the ocean into the architecture itself, multiple private terraces off nearly every room, and a rooftop terrace with solar integration and built-in seating for open-air living above the treeline. A separate downstairs floor level houses an additional bedroom suite with its own shower room and sanitary facilities, while an external storage room and covered porch complete the ground floor.

This is a residence conceived around the horizon — every principal room opens onto a terrace, and the architecture itself steps back to let the ocean lead.

￥810,000,000. Freehold. Full renovation.

The Neighbourhood:
Ishigaki’s Ibaruma district sits on the island’s quieter northern coast, well removed from the resort density of the south — a landscape of turquoise water, undeveloped shoreline, and a pace of life defined by the reef rather than the road. The area remains subject to Ishigaki’s landscape preservation ordinance and Okinawa’s natural environment conservation regulations, ensuring the surrounding coastline retains its character over the long term.

Ishigaki Airport is approximately 25 minutes by car, connecting the island directly to Naha and, from there, to mainland Japan and international gateways across Asia. The immediate surroundings remain sparsely developed, with only a handful of boutique cafés and guesthouses along the coastal road — a setting defined by seclusion rather than proximity to commercial infrastructure.
