Tsukuba Plant edition
In this edition, we will introduce the town where Mitsubishi Materials’ Tsukuba Plant, which supports the company’s metalworking business, is located.
The Tsukuba Plant is located in a place full of natural beauty, from which Mount Tsukuba, whose fame is exemplified by the old saying, “Fuji in the west, Tsukuba in the east,” can be seen.
It was fully relocated from Tokyo to Joso-shi, Ibaraki, in 1992, and celebrated its 30th year of operations in April 2022.
