President of ventilation fan business with annual sales of 500 million talks about his entrepreneurial experience The event will be held in Kamakura on Monday, October 16, 2012!

Despite being 30 million yen in debt, the company grew rapidly over the next four years. Overcame the Corona crisis.


Denkyo Planning Corporation (Location: Ota-ku, Tokyo; President: Masahiro Kiyoi) specializes in ventilation fan installation and has reached 500 million in annual sales in four years. He often appears at gatherings of local business owners, and will hold a meeting on Monday, October 16, 2023, at which he will share the story behind his business at a gathering open to anyone who is interested in starting a business.

Tokyo Head Office

The staff went from being almost inexperienced to becoming ventilation fan installation professionals.

The number of people who want to start their own businesses is increasing.

Since Corona, there have been many entrepreneurship seminars, including online business seminars. Starting with university student entrepreneurs, even the pre-retirement generation is gaining momentum to start their own businesses. However, there are many people who feel that the smart stories of successful entrepreneurs are out of touch with reality, and some people would like to hear more muddled, real-life stories. I hope my story of hardship will be of help to those people.

I started my business in Hiroshima and moved to Tokyo.

In 2000, when I was 29 years old, I left my job and started my own business in Hiroshima. After failing at selling used furniture, I started selling housing equipment. Gradually, the business took off, and in 2011, I incorporated the company. Sales started to rise, but in 2018, I had to take on 30 million yen in debt for my new business. Then I studied direct marketing. Taking a cue from customers who said, "When I want to replace my exhaust fan, I don't know where to ask for help," I launched a business model specializing in "exhaust fan replacement. We believe this is the first model of its kind in the industry in Japan (according to our own research). Later, the company relocated its headquarters from Hiroshima to Tokyo and expanded its business by utilizing the Internet in earnest. We came out of the depths of bankruptcy, and have since climbed back to the top. He will speak frankly about how he rebuilt his business and how he trained his employees.
