About Us

Our Philosophy

■Message from Our President

My passion for hospitality started as a weekend hobby. I used to stay in hotels all over Japan and abroad, imagining myself as a critic as I indulged my love of travel, hotels, and interior design.My dream was to one day create the ideal hotel.I chose international trade as my career because it gave me the chance to continue traveling and coming back to visit my favorite places.For me, hotel management was the perfect way to make my dream come true. And I want to keep nurturing that dream and making it grow.

My ideal hotel is a space designed with a feminine sensibility, where you can relax and go at your own pace. Our company is still just starting up, but as we pursue our dreams, we will strive to build it into a company that rises to every challenge without fear of change or failure.

Our goal is to welcome guests from all over the world and provide them with a uniquely Japanese service experience.It’s my hope that our hotels can play a role in preserving the unique natural, cultural, and artistic heritages of communities throughout Japan.

■Message

Hotel management has been my dream in life. I’ve traveled the world, and journeyed to many destinations as a hobby, with the goal of creating the ideal hotel someday. That was the reason I chose the trading industry as my career, to be able to travel the world and visit my favorite places again.

I’ve always valued and cherished a growing dream to be able to design a facility, that has the ability to transform you into a space where one can unwind and relax after a long journey.


Many challenges arised as I created my company, but I wasn’t afraid of making changes and enduring failures. My goal is to welcome guests from all over the world and provide them an opportunity to experience the uniqueness of Japan that is very meaningful to me personally. Please enjoy your stay with us.
