Gunma Seiko G1 Association – Training Seminar Held

On October 17, 2025, a lecture was held as an event of the Gunma Seiko G1 Association (Kyoryokukai / Partner Association).
We welcomed Dr. Yasuhiro Yanagida, Director of the Gunma Prefectural Cancer Center, as our guest speaker. He delivered a lecture titled “Let’s Understand Cancer Correctly.” As Dr. Yanagida specializes in breast surgery, the seminar was held at the cafeteria of Gunma Seiko’s Kamikawa Plant and was attended mainly by female employees of Gunma Seiko and its partner companies.
Although this may be somewhat lengthy, we would like to share excerpts from his presentation materials below:

  1. Around 1954, cancer surpassed tuberculosis as the leading cause of death in Japan. Currently, one in two men and one in three women in Japan are diagnosed with cancer. However, up to their 50s, more women than men develop cancer due to cervical and breast cancers.
  2. Cancer is a disease that occurs when genetic mutations arise in one’s own cells.
  3. Risk factors for cancer include smoking, obesity, infections, and genetic predisposition, but the greatest risk factor is aging.
  4. Cancer prevention measures include quitting smoking, moderate alcohol consumption, regular exercise, infection screening, maintaining an appropriate body weight, and a balanced diet.
  5. Cancer cells can spread throughout the body via the bloodstream, grow in other organs, and damage them.
  6. Cancer stages are classified from Stage 0 to Stage 4.
    ・At Stage 0, local treatment (surgery or radiation) is usually sufficient.
    ・At Stages 1–3, there may be microscopic metastases beyond the primary tumor. Local treatment combined with systemic therapy (such as chemotherapy or hormone therapy) to prevent recurrence is recommended.
    ・At Stage 4, systemic drug therapy is the main treatment, with radiation therapy and other treatments provided according to symptoms.
  7. For Stages 0–3, the goal is cure. Apart from certain special cancers, Stage 4 is generally not curable, and treatment focuses on prolonging life and relieving symptoms.
  8. When diagnosed with cancer, it is important to consider how the disease will affect your life.
  9. It is important not to be swayed by claims of “special,” “immune-based,” or “side-effect-free” treatments, but instead to choose reliable treatments covered by appropriate medical insurance.
  10. The purpose of cancer screening is to reduce cancer-related deaths through early detection and treatment.
  11. It is important to live a lifestyle that reduces the risk of cancer. Undergoing effective cancer screening is essential, and if cancer is detected, it is important to remain calm, understand the stage and characteristics of the cancer, assess your current situation, and develop an appropriate treatment strategy.

Dr. Yanagida, thank you very much for your valuable lecture. We learned that what we can do is practice appropriate cancer prevention and undergo regular, effective screenings. And in the unlikely event of a diagnosis, it is important to stay calm and carefully consider the best course of action.

Performance Evaluator Training

On Tuesday, October 8, a Performance Evaluator Training session was held in the cafeteria of the Fujioka Nishi Plant under the guidance of Mr. Murai from Murai Management & Labor Support. Six newly appointed evaluators from five departments participated in the training.

The objective of the program was to enhance the evaluation skills (basic knowledge and competencies) required for evaluators and to ensure a thorough understanding of the company’s personnel system, including its structure and rules.

Through lectures, mock exercises, and interview practice sessions, participants were able to learn the knowledge and mindset necessary for evaluators. The training also provided a valuable opportunity to strengthen communication and build relationships across departments.

We hope that the participants will apply what they have learned in this training to their future roles and strive to become trusted supervisors.

Emergency Evacuation Drill Conducted

Evacuation and fire-extinguisher drills were conducted on October 7 at the Kamikawa Plant, on October 14 at the Kamikawa East Plant and the Die Technology Center, and on October 16 at the Fujioka West Plant.
Assuming a magnitude 5 earthquake, the drill followed the sequence of: emergency broadcast, evacuation to designated assembly areas, and confirmation of employees’ safety.
We also received instruction from Kanto conservation and disaster prevention Co., Ltd. on the proper use of fire extinguishers, followed by hands-on fire-extinguishing practice using traffic cones as simulated flames.
Although this is an annual exercise, disasters can strike at any time without warning. We will continue to conduct regular drills to ensure that every employee can evacuate calmly and swiftly in the event of an emergency.

Get-together with New Graduates

On Thursday, December 25, we held a pre-employment networking event for students who are scheduled to join the company in April.

Although they appeared slightly nervous at first, the atmosphere gradually became more relaxed, conversations became lively, and the time passed very quickly.

It was a very meaningful opportunity to deepen our connection with the students who will be joining us in April. We also feel that, by speaking directly with senior employees, the students were able to further build up their expectations and enthusiasm about starting their careers with us.

Year-End Party

On December 12, 2025, the company held its year-end party at Yamato-ya in Fujioka, with a total of 77 employees in attendance.

Although the time was limited, the venue was filled with a warm and friendly atmosphere throughout the evening. Employees who do not often have the chance to talk with one another were seen naturally engaging in conversation. While enjoying a delicious meal together, we reflected on the past year and shared our appreciation for each other’s hard work, making it a truly meaningful occasion.

The raffle drawing was especially exciting. The joy of the winners and the applause from those around them spread throughout the venue, and the smiles on each participant’s face were truly memorable.

As a way to conclude a busy year, the event provided a refreshing and uplifting experience, offering a wonderful opportunity to renew our spirits for the year ahead.

Golf Club Competition

On December 27, the golf competition held at Obata-go in Kanra Town, Gunma Prefecture, marked a memorable day befitting the Golf Club’s final activity of the year. A total of 12 members participated. Despite the busy year-end season, such a strong turnout once again demonstrated the unity and camaraderie of the club.

As expected, the weather was bitterly cold, and the early morning course truly felt like midwinter. In particular, the greens were frozen, causing balls to roll far beyond expectations and creating extremely challenging conditions. Precisely because it was not easy, the joy of hitting a great shot was even greater. Being able to encourage one another and play together highlighted the unique appeal of a club competition.

More important than the results, however, was that everyone completed the round safely and concluded the year’s final activity with smiles. It was a fitting way to close the season.

Looking ahead to next year, when we return to the course in warmer weather, each member carries with them lessons from this experience and a renewed determination to show improvement.

New Face

Introduction to Y・M
Production Control Department

Nice to meet you.
I have recently been assigned to the Production Control Department.
In my previous job, I worked in the service and customer service industry. Since this is my first time working in a factory environment, I initially had no idea about the to-dos. However, with the guidance and support of my senior colleagues, I am gradually learning my responsibilities day by day.
I will do my best to contribute to the company as soon as possible.
Thank you very much for your support and guidance.

Introduction to R・A
Machining Section1

Nice to meet you.
I have recently been assigned to Machining Section 1.
Previously, I studied metal processing techniques and knowledge as a trainee at the Kumagaya Technical Vocational School. I am truly grateful for the opportunity to learn from and be guided by the respected senior colleagues here at Gunma Seiko.
Although there are still areas where I need improvement, I will do my very best to master the basics one step at a time and build a strong foundation.
In my personal life, I love delicious food, especially sweets! To make sure I don’t “outgrow” my uniform, I try to do light strength training every day (though I occasionally skip a day).
I realize I still have much to learn and may cause some inconvenience along the way, but I will spare no effort in striving to contribute as quickly as possible.
Thank you very much for your guidance and support.

GST Topics① KAIZEN 2025 Presentation Meeting

On November 1, we held the KAIZEN 2025 improvement activity presentation meeting.
The improvement activities were carried out over a three-month period from July through October.



This year, the event was held in a larger venue.
At the opening ceremony, President Marumo provided an explanation of the rules.
This year, a total of six teams delivered presentations, reporting on 93 improvement themes and impressive number of initiatives.
Prize money was awarded to all teams according to their ranking.
In Thailand, there are many opportunities to take commemorative photos at events like this.

During the Q&A session, discussions were so lively among the Thai participants that there was hardly any opportunity for the Japanese members to join in.
Below, we would like to introduce three examples of improvement initiatives.



【Improvement Example①】Installation of a guard to prevent forklift forks from directly striking equipment.

【Improvement Example②】Production of a dedicated cart to improve the transportation efficiency of packaging materials.

【Improvement Example③】A cart was designed and manufactured at the same height as the pallet so that boxes no longer need to be lifted, thereby reducing the physical burden on workers.

GST Topics② NEW YEAR PARTY

On January 17, we held a New Year Party on the company premises. In order to express our condolences for the passing of Her Majesty Queen Sirikit in October 2025, the event was held with attendees dressed in white and black attire.


A stage was set up in the company parking lot.
Although the judges were Japanese, many of the performances and themes were difficult for them to understand, which made the judging quite challenging.
【Raffle Drawing】
 
This yearʼs first prize was an electric motorcycle. In addition, many other prizes, including home appliances, were awarded.
【Live Performance】
 
For most of the Thai employees, this was probably the main highlight of the event.
In recent years, conflicts between nations, including those involving Thailand have increased, and there has been no shortage of troubling news.
In times like these, we hope that through events like this, everyone can refresh their spirits and continue to work together to overcome challenges as a team.
