People are attracted to leather goods such as shoes or bags. It's full of Japanese craftsmanship and creative spirits.
At the Kabankobo Yamamoto in Nara Prefecture, they are making school bags that are made for elementary school students.
Including cutting, sewing, the entire process involves a few hundred steps which has to be maintained by hand within the factory.
Kazuhiko Yamamato, Managing Director of Kabankobo Yamamoto, said, "This style of making products from one piece of leather all inside the factory has not been changed since my father's time. Once the job is divided into sections, there will be parts that are overlooked, so conducting all the tasks in the factory is connected to high quality production."
First of all, the shape is taken from the leather.
The next step is using CAD to cut it. The cut leather's thickness is adjusted based on the parts that will be used on.
Like attaching metal accessories on to the shoulder strap, the process of the bag making is in progress.
The fractured surface is painted several times with Varnishes and finished beautifully.
Each section is sewed together carefully with sewing machine.
The corners of a school bag are created by pushing the leather to make ruffles. The beautiful fan shape is called Kizami, which is a traditional technique for Japanese craftspeople.
Finally, each section sewed together with thick threads. The bag is now complete.
Yamamato further said, "We look forward to practicing our creative spirit and techniques that are fostered by school bag making into other areas."
Leather goods can be used for longer time if it's taken care of.
Located in Chiba prefecture, COLUMBUS CO. LTD. makes cream that maintains the shoes.
Koji Kodaka of The Columbus Co Ltd said, "Including black, we have about 70 color variations of the shoe cream products. Leather goods are similar to human skin because people are also animals. By alimentation, leather goods are kept in good shape and will be long-lasting."
Dirty shoes can become very clean just by taking good care of them.
First of all, use a brush to clean off the dust carefully. Then use a cleaning sponge to remove the dirt.
After it becomes clean, apply the cream. The important point is to spread a thin layer of cream evenly on the leather.
After the cream dries polish with a soft cloth. The brightness of the leather can be restored this way.
Chika Kobayashi of The Columbus Co Ltd said, "Wax can polish shoes and protect the surface of the leather. We are confident that the wax emulsifying technology is unique to our firm."
Crafted with labor and time, depending on how they are maintained, the leather goods can be used for a long time.
