Founder Ryozo Yonehara graduated from the University of Tokyo and worked for the Tokyo Metropolitan Government.

In 1988, he became secretary to Tokyo Governor Shunichi Suzuki. He accompanied the governor and participated in national commemorative projects and various events of the Tokyo Metropolitan Government.

From 1992 to 1994, he worked at the Japan Local Government Center in New York.
While attending dozens of international conferences in the U.S., he learned that spouse programs and evening activities were an integral part of MICE.
After returning to Japan, he worked as the General Manager of Tokyo Big Sight, Japan's largest convention facility, where he was involved in MICE operations. At that time, he was keenly aware of the lack of activity menus such as cultural experiences.

In 2008, he retired from the Tokyo Metropolitan Government and founded the NPO Institute for Japanese Culture Experience and Education (IJCEE). IJCEE's mission is to provide Japanese cultural experience programs in Japan that can be enjoyed by foreigners.

IJCEE also worked to train specialists in Japanese culture who would be responsible for such programs.
At its inception, the company had only one employee and annual sales were 2 million yen.
Sushi-making and tea ceremony experiences were offered as cultural experiences that a single customer could participate in.

In 2009, the number of employees increased to two, and the number of members grew to 138, with sales of 11.42 million yen.
It was the first organization in eastern Japan to successfully commercialize a Japanese cultural experience for FITs. It was the second in Japan, after WAK JAPAN in Kyoto.

The majority of IJCEE members are nationally certified tour guides.
Among the more than 1,000 members are masters and specialists in tea ceremony, calligraphy, flower arranging, cooking, and shamisen.
These specialists are unique in that they provide cultural experiences in foreign languages.
In addition, even those guides who were not gifted in Japanese culture developed their talents in areas in which they excelled, such as interpreting, sumo, Tsukiji, and the arts.
In other words, while they have the foundation of being guide interpreters, they have also developed their expertise.

2014- IJCEE membership grew to 640 members, and the revenue division was spun off from IJCEE to form True Japan Tour K.K. (TJT). Ninety-seven IJCEE members invested in the company.

2015-TJT's sales were approximately 100 million yen.

2017 - The head office was moved to Shiba Koen, Minato-ku. 30 meters from Tokyo Tower.
TJT's sales exceeded 500 million yen, and the number of IJCEE members exceeded 1,700.

2019-The company established Origuru-tei and Senshin-an, two dedicated facilities of approximately 200 square meters equipped with kitchens. Sales exceeded 700 million yen.
Since its establishment, the company had an average annual growth rate of 170% over the past ten years.

January 2020 - the company was hit hard by a new coronavirus infection.
As a travel agency specializing in inbound travel, the damage was severe.

2020- The national tourism agency entrusted the company with a project.
The program involved interpreter guides teaching cross-cultural understanding and language skills to employees of accommodation and transportation facilities.
Interpreter guides throughout the country were unemployed, and this was also an employment measure for these people.
In addition to these programs, we were commissioned by the Japan Tourism Agency, the Tokyo Metropolitan Government, the Chiba Prefectural Government, and the Tochigi Prefectural Government, among others, to cover the shortfall in revenue.
After a three-year hiatus from 2020, travel to Japan resumed in October 2022.

2023- Approximately 3,500 people experienced sushi and 4,000 people experienced a tea ceremony.

2024- In addition to the previous experience programs, the company plans to expand them by offering ninja and samurai experiences.
