Q. Can you also support projects in countries outside of Japan?
A. Yes, we can. We can connect you with a Japanese architect who can take projects in foreign countries. You can either ask the architect to (A) work only on the design of your building, which is easier to be done remotely, or (B) manage and supervise the entire process, including the construction.
You will have more accuracy to build your house as it was designed in option (B) as the same person who designed your building will also supervise the construction process, but it will also cost a little more fee as you will need to ask the architect(s) to travel to your location.
Only residential houses?
Q. Does only deal with residential houses?
A. We can support you in any kind of architectural or design needs. Not only residential houses but also large buildings, commercial facilities, resort hotels, interior design, renovations... anything an architect can design. Get in touch with us and find out how you can get your support.

Q. Can help us purchase a property?
A. Yes. We have partners who have expertise and license in real estate brokerage and we will be able to work together with those partners to support you in purchasing a property.
Q. 紹介されるのは住宅案件だけですか?
Q. Do we have to build with an architect?
A. You don't. If there is a specific builder or a house maker you like, we can support you in those kinds of processes as well. In those cases, we are asking for a separate service charge for project management and communication support, coordinating your project with all stake holders. Contact us for free to know how much the service charge will be in your case.

We do recommend to most of the clients to at least have a casual chat with an architect as you will have access to substantial degree of information. Generally, the flexibility of architects work well in achieving what foreign people want in their house, which is not necessarily the same as what Japanese people want.
