Four MLB pitchers from Japan have recently experienced a collective slump, leaving fans in anticipation of possible redemption. The 'total collapse,' as the headline captures, suggests a string of poor performances from these players on the pitching mound in recent games. The specific players, dates of the games, and contributing factors to this slump are not provided in the headline, but it conveys a sense of urgency for improvement and recovery for these globally recognized athletes.

The performance of Japanese athletes in international sports such as Major League Baseball (MLB) is highly important in Japan. These athletes are seen as national symbols and an embodiment of Japan's talent and potential on the global stage. Their performances directly affect national pride and the support for such athletes in Japan is immense.

In the US or EU, the performance of domestic athletes in international leagues similarly impacts national pride. However, the level of these impacts varies depending on the popularity of the sport and individual athletes. In the case of baseball, it's one of the major sports in the US, so the performance of American athletes in MLB is under constant scrutiny and is of high importance to fans and the nation.
