An unexpected discovery of a significant amount of stolen money surprised Japan. During a traditional "courage test," participants stumbled upon 100 million yen, which is suspected to be linked to a large theft. The police are now investigating the unexpected find to determine its origin. The event took place at an undisclosed location and timeframe as the investigation is ongoing. The discovery was not simply a windfall, however, as it has instigated fear and intrigue among the local community.

The incident grabbed the attention of the Japanese public due to the substantial discovery during a local "courage test” in which individuals venture into eerie places to test their bravery. The practice has a cultural significance in Japan, often related to ghost stories and local legends. This case introduces a new form of potential danger in these tests and prompts discussions on safety and public responsibility.

In the US or EU, this might resemble the discovery of a significant amount of money that could potentially be linked to a bank robbery or similar high-profile theft. The police would traditionally take over the matter, and the events would attract significant media interest. Due to the cultural differences, there would not likely be an exact comparison involving a "courage test.
