Job Introduction
PROFESSIONS
Research and development position/Optical connection technology
Research and development into light can be divided into two main areas:
- Ultra-precision molding, design, evaluation and new product development of optical connection parts, material research, prototyping, etc.
- Product development required for the IOWN concept, new product development related to optical connection technology in general, material research, prototyping, etc.
With over 20 years of experience and a proven track record in the development and manufacture of MT Ferrule, a multifiber optical connector component, we are developing cutting-edge, high-precision, high-density ferrules and related technologies that contribute to the ever-evolving communications infrastructure.
STAFF
-
We focus on improving the quality of MT Ferrule.
From the first year to existing products and new products
Responsible for a wide range of tasks.I polish, inspect, measure, and evaluate various MT Ferrule, aiming to improve and stabilize quality. It is not easy to achieve the precision required by the standards, so I work on improving every day by changing molding conditions while consulting with mold adjustment and molding staff and referring to past data. Since I originally studied a field other than optical communications, I had a lot of difficulties immediately after being assigned to the position. However, the quality and speed improved with each session, and from my first year I was given a wide range of responsibilities, from existing products to new products.

Research and development position/Optical connection technology
Required knowledge and skills
During my student days, I studied inorganic chemistry, and after joining the company, I was introduced to the business and received factory training as part of my new employee training, but the rigor of the work I've been doing since being assigned to the company is on a whole different level. Before being assigned to the company, I was conscious of doing exactly what I was told, but since MT Ferrule are not a product that you can make just by following the steps, it's important to understand the situation and think about it. Currently, I think about each job on my own, put it into practice, and correct my mistakes as I go along. I've also started to think deeply about prioritizing, meeting deadlines, and reducing costs.
Enjoying the fun of work and feeling like you're growing
I started living alone after I started working, but I feel very fulfilled because I can spend my time after work and on holidays on hobbies and self-investment. In personnel evaluations, there is a section for challenges that you can write down the challenges you want to take on. Among the skills that I can use at work, I set myself the goal of obtaining a qualification in mechanical design. One of the things I enjoy is the time I spend studying with my peers, separate from work.
Since I was first assigned to the position, my seniors have been teaching me in a clear and careful manner, so in the future, when I have junior colleagues, I would like to support them in the same way so that I can communicate more clearly.
Manufacturing technology job/Optical communication products
In my manufacturing engineering position, I perform tasks such as mold adjustment, molding, cleaning, polishing, inspection, and evaluation to produce our main products multifiber optical connector and MT Ferrule.
MT Ferrule play an important role in connecting optical fibers as thin as a hair with high precision to deliver optical information to data centers. Hakusan 's strength lies in its manufacturing technology that can create products in increments of 0.1 μm, and careful attention and collaboration with development is essential to achieving world-class quality.
STAFF

The mold specialist is knowledgeable about the entire manufacturing process.
Playing an important role in mold manufacturing technology.When I first joined the company, I was in charge of polishing optical communication products and line work for lightning protection products. After that, I worked on the processing of precision molded products for automobiles and all manufacturing processes for optical products. Currently, I am in charge of molds, which are the core of manufacturing technology, and I adjust, mold, and evaluate molds, while working on building a mass production system for new products.
We are promoting the development of multi-skilled workers in the Manufacturing Technology Department, but currently I am the only one who can carry out all processes, so reporting, communicating, and consulting with others in the workplace is essential so that I can act flexibly. -

Manufacturing technology job/Optical communication products
Required knowledge and skills
Since I am in charge of the molds that determine the finished product, my daily challenge is to achieve the standard precision and ensure stable production. There is no perfect method for making adjustments to the submicron level, and I need to "repeat until it works" based on the condition of the machine and my senses, so patience is more important than skill. Even if the adjustments go well, parts can wear out or the mold can shift, which can lead to defective products, so when I find a problem, I immediately discuss it with my colleagues and start working on a solution. Some things can be put into action right away, but other times I have to go as far as changing the design of the mold parts, which can take several months, so I'm always thinking about speed and priorities.
Enjoying the fun of work and feeling like you're growing
One of our strengths is our manufacturing technology that realizes high precision and high quality. As networks develop, products become smaller and denser every year, and it is extremely difficult to achieve sub-micron precision. Even for products that we take on from optical development to mass production, it can take several months for them to pass quality standards. Due to this level of difficulty, stable production is difficult, and the sense of accomplishment when we tackle something that is unique in the world and create it is exceptional!
internship
INTERNSHIP
You can imagine yourself working there!
There are two internship programs available.
- Practical internship: You can get a compact experience of the process that engineers go through.
- Practical internship: Students will tackle real-life problems and even make proposals based on their fields of expertise and interests.
Test and discover the skills you can use in your work!
You will be able to work alongside engineers in a real workplace and engage in activities that are close to work. We hold interviews in advance to confirm the students' purpose for participating, knowledge and skills, so that they can learn a lot, not just gain experience. We will proceed with the program so that you can utilize your experience and ideas.
Students from all over the country who want to study are welcome!
Since we are engaged in niche manufacturing and research and development, we have related laboratories all over the country. Therefore, we provide allowances for travel expenses, partial accommodation expenses, honorariums, etc. so that we can respond to students who are interested regardless of distance.
Participating students have commented that they "learned about the differences between university and corporate research" and that "the review time and discussions during the final presentations gave me new ideas for my research."
