Motto of the 14th generation

My motto is "貫日精誠震天下," a seven-character phrase from an ancient Chinese text.

If translated into Japanese, it could be expressed as "If you strive to be true to yourself day in and day out, you will be able to shake the whole world" or, in a more modern way, "If you continue to live faithfully day in and day out, you will eventually achieve great deeds. It is said that even in war-torn ancient China, sages taught many people that no matter how hard life was, if they continued to live faithfully, they would eventually achieve great deeds that would shake the whole country.

In fact, my name, Nobuo, has this one character in it.


Nobuo Yoshida, 14th President and Representative Director

Ibasen's Approach

We do not have a family motto in our 400-year history as a company. Nowadays, the question is often asked, "Who is the company for? Our answer has remained the same for 400 years. Our family motto is "trust" and "contribution to society" through our business. In the middle of the Edo period, the Yahagigawa River bridge in our hometown of Okazaki was washed away by frequent floods. Each time this happened, we merchants from Enshu and Mikawa were willing to undertake the bridge replacement work, thereby contributing to the local community. Today, the company's profits are fairly returned to employees, and we contribute to society through taxes, but nothing has changed in our approach. We believe that this continuous process is "trust. And it is our customers who support that trust. We believe that the accumulation of customer satisfaction through unashamed products is also linked to a long history of trust.

The Story of the Birth of the World City "Edo" Author: Nobuo Yoshida

From the postscript

In the year 2020, our company celebrates 430 years in business. A normal company would probably publish a commemorative journal that describes the company's history in the year of the anniversary. However, even if we wanted to publish a commemorative journal, we have no documents from 400 years ago. According to the oral tradition handed down from generation to generation, our founder moved to Edo with Tokugawa Ieyasu from Iba-mura in Enshu (present Higashi Iba-cho, Chuo-ku, Hamamatsu City, Shizuoka Prefecture), and was engaged in the development of Edo at that time. (omission) Therefore, I decided to compile our company's corporate gravel as a "novel".

We are publishing a full-length novel featuring Ibaya Kanzaemon I, a pioneer of Edo. If you are interested, please click here to view the book.
