For many years, our company has supported Japan’s culture of contracts and contributed to the development of a free market through the production of seals, printing services, and rubber stamps.
We are a company rooted in Japanese tradition and culture, with a history of more than 100 years.
Building on this heritage, we are working to combine traditional Japanese culture with the latest IT technologies.
Our mission is to protect valuable cultural traditions while creating innovative value for the future.
Our company is unique in that it possesses both cultural tradition and advanced IT technology.
Through IT, people can connect beyond national borders and cultures, gaining new values, experiences, and
knowledge.
We believe that this connection inspires creativity and new awareness that people have never experienced
before.
We strive to create content that is enjoyable both to use and to create.
Our goal is to rediscover the culture and traditions that modernization has caused many Japanese people to
forget,
and to share with those who are interested the values and technologies that we wish to carry into the
future.
Seals, known as 'hanko' in Japan, were introduced from Europe through China and eventually reached
Japan.
Japan is a rare country in the world that has a unique 'seal registration system,' which reflects its
distinctive seal culture.
Historically, a seal culture comparable to Japan’s can also be found in the Sumerian civilization.
Seals have contributed to Japan’s contract culture and the development of capitalism.
It is said that Western contract culture originated when a vertical contract between God and
humans
was transformed into horizontal contracts between people.
The sense of tension when stamping a seal is connected to the spirit that contracts are honored with a
solemn awareness, similar to the reverence one feels toward the divine.
Through the contract culture supported by seals, rights such as ownership, inheritance, and legal
authority emerged,
bringing modernization and capitalism to Japan.
Throughout history, seals have played an important role and contributed greatly to society.
