Residence
Not a building,
Create your ideal life.
No two homes built by ES-CON JAPAN have the same plan or concept. We imagine the people who will live there five or ten years from now, expanding our imaginations based on generation, family structure, lifestyle preferences, and other factors, to create a concept that maximizes the appeal of the land. Our homes are the culmination of ideals, carefully crafted without compromise in terms of floor plan, facilities, and design, and they add color to each individual's life.

Le JADE

A new landscape for the town. A new normal for the people. A one-of-a-kind home created with unconventional ideas. Unwavering individuality, solid quality, and a timeless design that only grows in value over time create a new normal that exceeds the ideal. It also brings more charm to the area and changes the townscape itself. The residence, named "JADE," will continue to emit a brilliant glow that will never fade, while making people and the town shine. As a home that "beautifies with age" rather than deteriorates with age, this condominium residence changes materials and designs for each town it is built in, and will mark beautiful time together with the people who live there and the town.
Grand Le JADE

Live proudly in a place of longing. An ideal residence standing in a place of longing. A beautiful home with the supreme dignity and quality befitting a premium address, even within Le JADE, which is particular about the charm and individuality of the town. In harmony with the streets steeped in history and culture, we create the joy of living in a proud place, true value that will never be swept away by the times, together with the town, over time. Of the "Le JADE" series, which is created with a focus on the charm and individuality of the town, this is a condominium residence built only in carefully selected locations steeped in history and culture.

TOPAZ

A residence where you can express your individuality and enjoy the "now" of life. TOPAZ has been loved as a symbol of the sun because of its transparent golden color. We hope that life here will be like its beautiful radiance. And in keeping with the name PAZ, which means peace in Spanish, we hope that it will be a spiritually rich environment where everyone can spend their days feeling fulfilled. As lifestyles become more diverse, each person should be able to enjoy this "now" moment of life in their own way. TOPAZ is a rental residence created to make such wishes come true.

Not only does it offer picturesque views, but it also breathes history and prestige. DIAMAS, the origin of the word diamond and meaning "eternity," aims to be a noble presence that shines with the timeless value of life, without being swept away by the trends of the times. In this high-quality, extraordinary experience, freed from the everyday, you will find time and space that can only be found here. DIAMAS HAYAMA is a condominium residence where you can savor the luxury of the ocean views that unfold before your eyes.
SEVENS VILLA
Karuizawa

Winner of the 2024 Good Design Award. A condominium residence built in the lush Karuizawa Minami-ga-oka area, aiming to live a life surrounded by the breath of nature. Inspired by the traditional Japanese idea of "teioku ichinyo," which describes the harmony between the garden and the building, we have created a space that blends into the local scenery while preserving as many existing trees as possible. We propose a new, relaxing villa lifestyle, where seven residences live side by side with the scenery created by the nature of Karuizawa.
OST Residence KARUIZAWA
