Monozukuri — The Manufacturing Spirit Behind Industrial Machinery

We are a metal processing company in Osaka, Sakai, that has been manufacturing core components for industrial machinery for over 40 years. While inheriting the know-how and reliable technology cultivated over many years, we are committed to "one-size-fits-all" manufacturing and carefully finish each and every item.
From their meticulous approach to each and every product, you can witness firsthand the commitment to quality that has been cherished in Made in Japan manufacturing, as well as the technical expertise that supports the production process.

Let’s Take a Look at the Tour!

Here's a look at the guided tour. The tour followed this schedule:
Factory tour ⇒ Metalworking experience

Factory tour

First, we will visit the factory and see the metalworking process where the skills of craftsmen and the latest equipment come together. Equipped with processing equipment that can handle everything from palm-sized parts to large parts up to 3 meters in size, the factory achieves high-precision manufacturing by handling processing, measurement, and programming in-house.
By seeing the manufacturing process and the movements of the machinery up close, which you don't normally get to see, you can truly understand why Japanese manufacturing is so highly regarded around the world.

During your visit, you'll have the opportunity to speak directly with the craftsmen who have been working with the machinery every day to create the products. It's a valuable chance to learn about the essence of manufacturing—things you can't learn from the internet or documents alone—such as the behind-the-scenes aspects of production, the meticulous ingenuity that affects quality, and the judgments and experiences unique to the field. The more you listen, the more you'll be drawn into the profound world of metalworking.

Inside the factory, you’ll find an impressive selection of around 300 drill bits ranging from 1 to 60 millimeters in diameter. By carefully choosing the most suitable tools for each material and application, the factory achieves an exceptionally high level of precision and beautifully finished results.

In addition, during the tour, participants can take part in a hands-on drilling experience that recreates a small part of the actual manufacturing process. Using large-scale machining equipment that is normally employed in metal component production, you’ll operate the machine with guidance from skilled craftsmen—making it a safe and accessible experience even for first-time participants.

Drilling a hole precisely at the intended position may appear simple at first glance, but it is in fact a delicate process in which even the slightest misalignment or difference in pressure can affect the final result. Through this hands-on experience, participants gain a deeper understanding of the complexity of metalworking and the high level of technical skill that underpins Japanese manufacturing—learning not only through knowledge, but through direct physical experience.

Metalworking Experience

During the metalworking experience, participants create a traditional Japanese spinning top using high-precision machining technology accurate down to 1/100 millimeter. By working with the same metalworking techniques used at actual manufacturing sites, you can personally experience the remarkable precision that defines Japanese monozukuri. 

Because the rotation of the spinning top depends on the position and depth of each hole, participants refine their work through trial and error to create a truly one-of-a-kind original piece. This process of careful adjustment is part of what makes the experience so engaging, offering a deeper appreciation of the craftsmanship behind precision metalworking.

The finished spinning top is crafted with such accuracy that it can spin for more than 10 minutes. After completing the experience, you can enjoy watching it spin on the spot or take it home as a keepsake. The smooth motion made possible by high-precision machining allows you to experience firsthand the superior quality and technological excellence that define Made in Japan craftsmanship. Suitable for both children and adults, this experience combines learning and enjoyment for visitors of all ages.

In the activity space, you’ll also find a variety of other toys and creations made using metalworking techniques. Alongside the metalworking experience, take time to explore the creativity and fascination of Japanese monozukuri.

Tour Details

During the factory tour, you can visit the metalworking manufacturing site, which is not usually open to the public, and see the latest processing equipment and the high-precision skills of craftsmen up close. A major attraction is that by learning about the machines and processes used to actually make products, you can gain a deep understanding of the technical capabilities and commitment to quality that Japanese manufacturing has cultivated over many years.
Furthermore, the metalworking experience program offers a hands-on program where participants can create traditional Japanese toys using precise metalworking techniques. By experiencing the delicate and wide-ranging skills of craftsmen and engaging in hands-on creation, participants can truly understand the difficulty and enjoyment of metalworking, as well as the sense of accomplishment upon completion.
This program goes beyond mere sightseeing; it's a valuable opportunity to experience Japanese manufacturing culture firsthand, blending learning and hands-on activities.
