An individual has successfully traversed Japan across three different eras without letting his illness dampen his spirits. The journey started in the Heisei era, continued through Reiwa, and recently concluded. Throughout his extensive travels, he beneficially engaged with local cultures, traditions, and people, thereby gaining a wider perspective of the country.

Traveling across all 47 prefectures in Japan is considered a significant feat, symbolizing perseverance, patience, and a deep respect for the country's culture and history. Additionally, the concept of enduring through illness without losing spirit ("gaman" in Japanese) is highly valued in Japanese society.

In the U.S or EU, similar situations are dealt with significant importance too. Individuals overcoming personal challenges and traversing extensive regions gain considerable admiration. However, there is less emphasis on the temporal aspect (i.e., doing it across eras), as this concept is more specific to Japan's era system.
