In the heat of the summer, commuters of Sapporo's subway system are left sweltering due to the lack of air conditioning. Amid rising temperatures and the ongoing summer season, travelers are voicing concerns over the uncomfortable and potentially hazardous conditions. With the current set of challenges, the public and authorities are now in talks to address the situation.

In Japan, weather conditions and their direct impact on daily life draw a high level of attention. In this case, the issue of insufficient air conditioning in public transportation may be seen as a significant public concern, particularly due to Japan's often humid summers. Furthermore, respect for societal wellbeing and the overall comfort of the community are paramount.

In countries like the US or the EU, similar incidents frequently spark public outcry and are quickly addressed by transportation authorities. Both regions have stringent regulations in place governing the operation and conditions of public transport, aiming to ensure the comfort and safety of passengers.
