Condominiums & Houses
We draw out the full charm

No two ES-CON JAPAN condominiums are alike in plan or concept.
We imagine the life of residents five or even ten years in the future – their generations,
family structure, lifestyles, and more – and create concepts that draw out the full charm of the land.
We build the stage for a one-of-a-kind life for each individual.

OST RESIDENCE KARUIZAWA

Residence surrounded by dense green forest

In ancient times, jade was believed to have the power to revive life, offering perpetual youth and longevity. Prized for its seemingly eternal light, we named our new apartment brand (Le JADE) after it in hopes that these living spaces too would continually increase the value of their residents’ lives regardless of times or generations.
