MCZ "manhole cards" distribution begins.

Manhole cards commemorating MCZ’s spring concert "Haruno Ichidaiji 2025," held last spring in Shibata City, Niigata Prefecture, have started being distributed for free at the city’s tourist spot, "Zoshunkaku."

Manhole cards are collectible items featuring manhole cover designs, planned and supervised by Japan’s sewerage public relations platform (GKP), and jointly produced by local governments and GKP under a standardized nationwide format. Since the first edition was issued on April 1, 2016, a wide variety of designs have been released by municipalities across the country.

Shibata City is encouraging people to visit again and explore the area, making this initiative part of efforts to promote tourism after the concert. Since distribution began on April 24, many people have gathered at the site, and social media has been filled with posts such as "Got it safely!" and "I want to visit Shibata again."
