Welding probably isn’t an activity that immediately comes to mind when thinking of things to do in Japan. However, located in the sleepy and rather unassuming town of Numazu is Kageyama Ironworks, which has recently opened Iron Planet as its ‘welding experience center’ and is touting it as the world’s first welding theme park!

Weld your Own Creations at Iron Planet

Iron Planet is a welding theme park that gives visitors an opportunity to weld their very own creations. The first Iron Planet was created in Fukui Prefecture as a part of Osada Industry and offered welding classes for beginners. The concept is now turning into a nation-wide franchise chain with the first new location being in Numazu, Shizuoka. This unique idea allows people to create a variety of things from nameplates to shelves. Regardless of your experience, Iron Planet will show you the ropes on how to make your very own iron work masterpiece.

Before you literally make sparks fly, Iron Planet will fit you from head-to-toe with heat-resistant gear, including their stylish jump suit and a welding mask. Tsubochi, who runs the workshops for the Iron Planet in Shizuoka, will supervise your experience and show you the basics to welding your first piece of iron. According to him, the majority of clients that visit Iron Planet have zero experience with welding, but soon find themselves enthralled after seeing their first spark.

Iron Planet hopes to see visits from foreign tourists as well once the country opens back up. With their location being close to Mt. Fuji, Tsubochi hopes that people stop by to experience the art of welding while sightseeing. Other locations for new Iron Planets in Tochigi and Kanagawa have also been announced.
