Peace of mind in dorm life.
I used to work independently as a house master for a dormitory housing students who come from all over Japan to attend high school in our region. That work has now been incorporated and launched as a business. Our goal is for the many dorm students and their families to enjoy dorm life with peace of mind, and for students to come to love the community where they study.
Drawing on my experience farming overseas, we also offer English interpreting that makes use of knowledge of the outdoors, plants and animals.

“co.” stands for cooperation and collaboration. We want to create places where people work together and find companions for the long run.

DORM DX APPMugi Dorm DX
Mugi Dorm DX is a dormitory management app for high school and university dormitories. Overnight-stay requests and approvals, and late/absence notices, are handled entirely on smartphones and PCs—no more paper forms or phone calls, and less work for house masters, teachers and parents.
As the form passes from student → parent → house master → homeroom teacher, it becomes hard to see where it is stuck.
Calling each homeroom teacher and parent one by one. The busier the morning, the more likely something is missed or miscommunicated.
Who stayed out when? How many absences this month? Tallying it up afterwards takes time.

Introduction video (approx. 4 min, in Japanese) | From request to approval and the admin screen Learn more about Mugi Dorm DX (in Japanese) →
An app for requesting and approving dormitory overnight stays on a smartphone. When a student submits a request, approval emails go automatically to the parent → house master → homeroom teacher in turn. The admin screen's “Today at the dorm” view shows at a glance who is away and who is due back, along with any requests waiting for approval.
An app that handles late and absence notices from the dormitory to the school and parents on a smartphone. When a house master fills in the form, the homeroom teacher and parents automatically receive an email. Each dorm logs in with a shared passcode, and notice history, monthly totals and printing are supported—no more phone calls or paper.
Get started with your school's Google account. No app to install, and your data stays in your school's spreadsheets.
Rosters and request data are managed within your school's Google account.
Password encryption, two-step verification for the admin screen and activity logs keep personal information safe.

Company
Kosuke Takei
Born in 1997 in Yonezawa, Yamagata Prefecture. While studying in the Department of Animal and Grassland Sciences, Faculty of Agriculture, University of Miyazaki, he served in his third year as head resident of the University of Miyazaki International House, a self-governed dormitory with residents from many countries. He graduated in 2020. Plans for agricultural training in the U.S. were cancelled due to the COVID-19 pandemic, so he worked at an agricultural corporation in his home prefecture of Yamagata, raising breeding Wagyu cattle and growing rice. In 2021 he joined the JAEC overseas agricultural training program and lived and worked on a goat dairy farm in Idaho, USA, returning to Japan in December 2022. He moved back to Miyazaki Prefecture in March 2023 and founded co.mugi LLC in 2024. Drawing on his experience as head resident, he now runs high school dormitories.
