While gradually learning the Vietnamese language, the Tanaka Scale Works team members struggled to communicate with the Ministry of Transport and team members from Viet Nam. That is when a reliable friend appeared. This was XXX Quan, an employee of Tanaka Scale Vietnam. Quan initially accompanied the team as an interpreter, but as he gradually began to understand the meaning of the project, he started to negotiate with a sense of responsibility as a member of the Tanaka family. He said, "I could feel the strong desire of my Japanese counterparts to reduce accidents in Viet Nam. I wanted to match that desire." Vice President Nha, noted, "I always talked with Quan about the passion of our Japanese teammates. They were seriously thinking about Viet Nam, so we should match them in that passion." Finally, the project moved forward with all gears engaged. Communication with the Directorate for Roads became smoother and there was no delay in the negotiations. Companies in Viet Nam that deal with camera systems for capturing the license plate number of overloaded vehicles also participated in the team, and cooperation with those companies also went well. Tanaka Scale Works also planned a study group in Japan. Members of the Directorate for Roads were invited to Japan to exchange opinions with the road technology researchers of Japan's Ministry of Land, Infrastructure, Transport and Tourism and Nagaoka University of Technology, as well as with team members from Tanaka Scale Works' head office and factory in Sanjo. They were also shown the roads in Japan. A social gathering was held after the study session finished, and a good time was had by all. President Tanaka recalls, "I was delighted to see them learn about the century-plus history of Tanaka Scale Works, and I could really feel their trust in us." In September 2017, the second phase, which involved installing the system on the other side of National Route 5, proceeded very smoothly. This more than made up for the delays that occurred frequently in the first phase. Tanaka Scale Works' team members once again recognized the importance of building relationships of trust.
