Seiji Shimohira
What is the atmosphere like within the company after the new employee is accepted?
The people we hired already had about three years of work experience in Japan, so they were used to Japanese people. In fact, it was the Japanese side that felt a bit distant due to the language barrier, and there was an awkward atmosphere at first. However, they are very expressive and can greet people with a smile. They also make a great effort to learn Japanese, so the Japanese employees naturally came to accept them.
What preparations were made for their arrival?
First, we welcomed Ms. Giang, a Vietnamese employee in charge of training, to our company. With her at the helm, we focused on Japanese language education and exam preparation for obtaining electrical engineer qualifications. We also asked her to review previously ambiguous work procedures, improve our training system, and clearly document the workflow.
What are your thoughts on training foreign players?
Becoming a fully-fledged electrician takes time. Even for Japanese people, it's said to take 10 years, so it takes even longer for foreigners who face language barriers. That's why I want you to think about your career in the long term. First, become someone who can be entrusted with responsibility, even on small jobs. From there, gradually gain experience, and in the future, I want you to become someone who can entrust the jobs you're in charge of to your juniors.
Please provide a message for companies planning to implement this system.
I believe it's important to treat everyone equally, without making distinctions based on whether they're foreigners or Japanese. They love parties, so I try to attend as much as possible, and I also make sure that the department head and site managers take turns attending to socialize. Another important thing is having someone like Jean. It's a huge help to have someone you can immediately consult with when you're in trouble, whether it's in your daily life or your studies. Before exams, he sometimes even gives online lectures from his home. Now, if anything comes up, everyone contacts Jean first. He's an indispensable part of the company.
Voices from those working on-site
We spoke to three Vietnamese employees of the company about their work and life in Japan, as well as their future goals.
ムアさん
I'm taking on a challenge in the construction industry! I'm able to work with peace of mind in a warm and supportive work environment.
MUA used to work in Vietnam making clothes with a sewing machine. "I really wanted to go to Japan, so I thought any job would do (laughs)." She said that learning the technical terms in the construction industry was difficult. She was also initially anxious about being a woman working on a construction site. However, after actually working there, she says brightly, "I felt at ease because I was touched by everyone's warmth and consideration."
KHANGさん
Starting from scratch with no Japanese language skills, I aim to become a reliable electrician.
Having come to Japan immediately after graduating from university and not having studied Japanese, he recalls, "I had a lot of trouble because I didn't know the names of the tools at all." Nevertheless, with the support of his teacher, Jean, he continued his studies and is currently challenging himself to study for the Class 1 Electrician's License. Although he says, "The content is very difficult," he remains positive. In the future, he aims to become a veteran electrician that his colleagues can rely on on site.
クアンさん
I'm learning Japanese and technology through sheer effort, by simply writing!
QUANG is a diligent student who studies Japanese not only through company training but also independently at home. When asked about her study methods, she told us, "Just write a lot." One thing that surprised her when she came to Japan was that Japanese people don't have many parties at home. That's why she smiled and said, "I really enjoyed drinking a lot with the president and everyone else on the company trip to Hokkaido."
