In 2021, J.One Real Estate was able to celebrate its 20th anniversary.
I look back on the last 20 years with a renewed sense of deep gratitude to all of you.
There have been countless encounters with wonderful customers in this long history page.
Everything on that page is the trajectory of our company, and I am excited that it may have been a wonderful “miracle”.
I would like to take this opportunity to express my sincere gratitude to everyone who supported us.

When I entered this industry in 2000, there were no mobile phones, and I fondly remember that I used to do business with pagers and fax machines. .
Nowadays, the number of virtual guides has increased significantly, and contracts are completely electronic.

The 9/11 terrorist attacks, the Lehman Shock, Hurricane Sandy, and Corona…
Over the past 20 years, there have been many incidents that shook the world, but as long as there is a country somewhere that has become a “winner” in the world, New York has risen no matter what.
I would like to continue to look a few steps ahead and support everyone who comes to New York to set up their lives with positive energy and creativity.

Going back to the beginnings of when I started my business 20 years ago, I am determined to achieve even greater progress over the next 20 years, with the aim of “seeking tomorrow’s trust rather than today’s profits.”

Once again, we would like to express our deepest gratitude for your continued patronage and ask for your continued support in the future.

J.One Real Estate’s unique concept

American real estate agents usually work on an individual basis, and each person works on a full commission basis.

Because it is a commission system, each individual becomes an individual store owner and just registers their individual name with the company, so loyalty to the company and customers tends to be very thin, and employees within the company tend to be very weak. It is a competitive system.

Under such circumstances, J. One Real Estate was born with a new concept. J. One Real Estate, the first “company organization” in New York, backs up customers with all employees! We will provide a service that will surely satisfy you.

Job Opportunities

J. One is always looking for people in New York, New Jersey, West Chester, Long Island, etc.
Looking for full-time, part-time, and interns. English proficiency required. Even an inexperienced person can do it.
