“onkochishin” was found in February 2011, it was also around the time of the tragedy, 2011 Tōhoku Earthquake and Tsunami, also known as the 311 Japan Earthquake. Hence, onkochishin business was all about the renovation & revitalization of the 311 at the very beginning. In December 2015, the 4th year of this company, we started to run our first property “Setouchi Aonagi”.It was an uphill battle at that time when we had insufficient money yet we also knew that was the opportunity to seize and we should hold up there. It was not easy at the beginning, but step by step, we are here now. Finally, our team has reached the 10th anniversary of onkochishin. Our first baby, “okcs Retreat Setouchi Aonagi”, has the honor to be the very first Japanese run hotel to be awarded the highest honor with Michelin 5 Star in 2018. And the next year, another onkochishin property, “okcs Retreat Iki Kairi” also humbly received the same honor from Michelin.

With all the blessing from people who support our work, we have been running more properties. Our revenue, teammates are 100 times then the first year. I want to take the chance to show my gratitude to our lovely guests, teams, owners of properties, business partners, and more than 70 shareholders. Thank you so much for the support and guidance. Although it takes so much time for me to reach here, it is far away from my goal.

Given the fact that we have achieved to create many projects we are so proud of, but the higher you go, the more humble you must be. Our team exists to find the hidden gems inside stone. It is our mission to focus on polishing all the stones until all of the hidden gems are shown to you.

We cannot wait to create more breathtakingly exciting and interesting moment to you
