Cumberland Japan was founded in 1994 and had imported and sold RVs made in the United States. Since 2006, we have worked on designing, manufacturing and sale of mobile homes consistently at the current head office (Nagano, Japan), aiming at the best mobile home in the world.

I got a feeling of the frontier spirit from this new products called trailer house (mobile home). I believe that learning from the world's technology and developing top quality mobile homes in the world with a theme "mobile" will lead to development of a new market in future Japan. And I certainly believe that we can suggest new lifestyles to many people.

Hideyo Harada
Representative Director

We have the largest exhibition site in Japan and domestic leading sales results.
We are manufacturing sturdy products which can withstand Japanese severe climate, such as coldness or heavy snowfall, etc. We also manufacture custom-order products by our long-time experience and technique.

Trailer houses are used throughout Japan for various uses, from personal uses such as a vacation house, a detached room or a room for family care, to business uses such as offices, shops, accommodation and so on. And also, at time of disaster, they are utilized in affected areas.

For owners' safe use, we have joined Japan Recreational Vehicle Importers' Association (JRVIA) which crates standards in Japan related to RV, and we are working on this business aiming at the best mobile home. And also, we participate in town revitalization projects, disaster recovery projects, events, etc., and work hard to contribute to societies.

Corporate History
Cumberland Japan was founded in June 1994 in Nagano, Japan, as a company which manufactured trailer houses in the U.S. and sold in Japan. And it was incorporated in January, 1995.
We provided mobile homes to the 1998 Nagano Winter Olympics, and also to stricken areas of the Hanshin Awaji Earthquake and of the Fukuoka Offshore Earthquake. We opened a guest house at the 2002 Salt Lake Olympics. At the great disasters of the Niigata Chuetsu Offshore Earthquake in 2007 and the Tohoku Earthquake in March 2011, we have been working on early revival with disaster victims and local governments. In 2007 autumn, we started making a sales agents network to promote mobile homes throughout Japan.

The logo expresses a tree (leaves and a trunk), designed with "C" and "L" of CUMBERLAND in tender violet color, to mean the harmony with nature.
