On May 9, 2024, an annual Shinto ritual, what is called “Reitaisai-Shiki” was held at Oyamazumi Shrine in Niihama City. The ceremony was filmed with the cooperation of Sumitomo Group companies that have sites in Niihama.
On May 9, 1691, the Edo Shogunate granted authorization for the operation of the Besshi Copper Mines. A Shinto ritual is held on May 9 every year, attended by representatives of eleven Sumitomo Group companies that have factories or offices in Niihama City, Ehime Prefecture.
Although the Besshi Copper Mines closed in 1973, representatives of Sumitomo Group companies continue to visit Oyamazumi Shrine in Niihama City on that date every year to express their gratitude and pray for safety.
