My view on the architecture of Tomorrow.

My hometown Amami Oshima is an island blessed with abundant sunlight, crystal clear oceans, filled with colourful flowers and a multitude of greenery and wild life. In a word, it is an ecological paradise. Growing up there, nurtured an understanding within my soul that every life has its own role in the environment, humans included and we are all interconnected.

This concept has been an integral intellection of my architectural thoughts.

I have designed and supervised the construction of more than 200 homes so far. This coincides with the fact that the core concept of architecture, which I regard most important, revolves people the architecture they dwell in, the house. The interest in houses has led me to other types of architecture for dwellers.

The projects in which I am most interested at the moment are resort facilities, hotels and auberges. Dwelling spaces for relaxation. My interest extends also to facilities for the elderly.

Resort facilities should be developed with a deep understanding for the region and aim for long lasting relationships with the local communities. It should incorporate locally available materials. Both in Japan and abroad.

Since 2013 I have been teaching at Kyushu University and also conducting research into facilities for the elderly. As Japan is considered the worlds fastest aging country with the greatest proportion of elderly residents, it is necessary for our national policy to pave the way. To this end it is essential for us to propose new designs and varieties for facilities. My aim is to study from single purpose (nursing homes and day care and small multi function) to large multi purpose. To city centric for the active elderly, designed with expert help to be fully integrated within the locality.

Executive Vice-President


Through architecture, I would like to achieve the following;
1. The welfare of humanity
2.To give back what we have taken from nature
3. To achieve spiritual happiness

Architecture is not just about forms and color. We listen to the client, to the unheard voices of the materials, the voices of the people working on site.

Out of all the communication, to capture the essence which we can mutually share and to hand on to the next generation a society, culture, environment and earth that we can all be proud of.

Managing Director


I am engaged in design with a wish to create architecture that will be inherited happily by the next-generation of children.

For an architecture that is long lasting, it is important that it weathers well, has high basic performance and also is loved by the user.

It is of utmost importance that we share our thoughts at high level of intensity to create an architecture that is long loved.

Furthermore, the most powerful thing about architecture is that it appears physically before us. Let’s create together, architecture that we can truly enjoy the depth of our thoughts and the physical power that architecture has.
