The "Sewerage" theme has ranked 16th in the "Popular Theme Rankings" compiled by Minkabu and Kabutan.

On April 21st, the Ministry of Land, Infrastructure, Transport and Tourism announced the results of a nationwide special priority survey (covering 535 entities and 5,332 kilometers) conducted in response to a road subsidence accident in Yashio City, Saitama Prefecture in January last year. The survey targeted sewerage pipes with a diameter of 2 meters or more that were installed before fiscal year 1994. As of the end of February 2026, the survey found that 748 kilometers require countermeasures, and 96 locations with ground cavities were confirmed (all have been addressed at this time). Of the 748 kilometers requiring countermeasures, 201 kilometers are considered high urgency, and the ministry is calling on the 277 municipalities managing them to take prompt action within one year, offering technical and financial support.

In parallel with the priority survey of sewerage pipes, the ministry is also advancing safety enhancement measures including revisions to pipe diagnostic standards. It has submitted an amendment to the Sewerage Act and related laws incorporating the legalization of diagnostic standards for evaluating pipe safety, which was approved by the Cabinet on March 27th.

In response to these changing circumstances surrounding sewerage infrastructure, interest in sewerage-related stocks has been renewed. While there was little notable movement among major related stocks on this day, NIPPON CHUTETSUKAN K.K. <5612> and KUBOTA CORPORATION <6326> showed firm performance.
