Message from the President

We specialize in sakan (traditional Japanese plastering), and have been entrusted with construction projects by major general contractors and housing manufacturers, working on large-scale buildings, factories, and apartment complexes.
Since our founding, our unwavering motto has been “integrity.” This value extends equally to the clients who place their trust in us and to the colleagues who work with us. We approach each task and person with sincerity, always striving to deliver more than what is expected—both as skilled craftsmen and as human beings.

Today, our team is a united and dedicated group of people whose ages range from late teens to 70s.
Young members join as apprentices, learning skills from experienced seniors and contributing their energy with enthusiasm.
Veteran craftsmen have passed on their knowledge and experience to create a group of top-notch professionals who embody true craftsmanship.

As one of the leading Sakan-focused construction companies in Kyushu, we are proud that many of our craftsmen continue to mutural improvement.
Every one of us takes pride in our craftsmanship, and the solid quality of “Sato Komuten” is achieved by finishing products that we are not ashamed to present anywhere.

We look forward to meeting the people who will work with us as we dream of further growth and the future.

Work Details

  • Floor Concrete Hold Down

    This job is to hold down the concrete after it has been poured and leveled on the floor. Since floors are vital to factories and hospitals, they are held down so that there are no uneven surfaces. The more you press down with a metal trowel, the more durable the floor will be. Concrete is a race against time. It is also important to have the experience to carefully level the floor before it dries, wait until it dries, and assess it.

  • Floor Mortar Application

    The mortar appropriate for the application is poured evenly on the floor. The thickness is evened out by shaking a ruler to prevent unevenness in thickness. Balconies and food factories are sloped toward drains, and motor sports are prepared to the millimeter level. It is a difficult job to match the usage and drawings.

  • Floor Leveling

    This is the process of creating an uneven floor by pouring a highly fluid mortar (leveling material) after a single pour of concrete. Leveling is a difficult job that requires a lot of experience, as it is done manually. It is mainly required at factories, hospitals, convenience stores, etc. Carefulness and accuracy are indispensable.

  • Wall Mortar Application

    The process of evenly applying mortar to a wall that is appropriate for its use requires concentration and patience, and is a great show of skill for a craftsman. Unevenness is noticeable when light shines on it, and there are also various factors to work with, such as gravity, temperature, and humidity. We work to achieve a beautiful wall down to the smallest details.

  • Diatomaceous earth plastering

    Diatomaceous earth plastering is required for entrances, reception rooms, galleries, and other spaces where people are entertained. The charm of plastering lies in the high quality of the workmanship, such as the daring to show the shape of the brush, the beauty of the regular pattern, and the way of application. Since it is the main wall used, finishing requires skill and is very rewarding.

  • Wall Concrete Striking Repair

    This process is used to clean up the wall surface that is created by sandwiching panels and pouring concrete. Since large panels are placed side by side to form a wall, there will inevitably be some rippling and bumps, which are sanded flat and then repaired evenly so that the cloth and paint can be finished beautifully.

and become a professional craftsman.

  • Apprenticeship

    Estimated
    duration
    3 to 4 years after joining

    As a new employee, you will work alongside senior craftsmen at a variety of job sites. You will learn about materials such as concrete and mortar, as well as the characteristics of different tools and surfaces.
    Since the work must adapt to changes in seasons and weather, the more sites you experience, the more your practical skills will grow.

    Each type of site—whether office buildings, commercial facilities, factories, hospitals, or schools—has different requirements. As you gain experience, you’ll also gain a deeper understanding of society and how buildings support daily life.

    By observing and learning from senior workers, you will gradually improve your skills.

    Recommended certification to aim for
    Nikyu Sakan Ginoushi
    (Second Class Plasterer)
  • Skilled Craftsman

    Estimated

    By this stage, you will have experienced all the basic processes and gained solid knowledge of various materials and tools.
    The goal now is to perform each task not only correctly, but with greater speed, efficiency, and precision.

    You will continue learning by observing other skilled craftsmen, while also developing your own strengths and areas of expertise. You may also begin mentoring junior workers.

    This is the stage where you refine your craftsmanship—aiming for neat, quick, and beautiful work through ongoing practice and collaboration with your peers.

    After years of experience as an apprentice and skilled craftsman, you may become a Lead Site Craftsman—a trusted presence on any job site.
    In this role, you are not only expected to perform high-level plastering work, but also to lead by example: mentoring junior members, checking for delays or issues, and helping the entire team stay focused and on track.
    You take a broader perspective, actively supporting both the quality of the work and the people doing it.

    With even more experience, you may step into the role of Foreman, taking charge of project coordination, client communication, and overall site supervision.
    Your responsibilities include keeping construction on schedule, creating a safe and efficient environment for the crew, and ensuring that no one is overburdened—or underutilized.
    You will manage time, costs, and resources with a wide view of the entire process, balancing productivity with care for your team.
