Japanese tradition is known for its rich and deep-rooted customs, one of which includes the high school tradition of gifting the 'second button' to a loved one. The practice traces its origin to the belief that the second button from the top on a man's uniform is closest to the heart and symbolizes love or special affection. Sometimes this button is given to a crush, and other times to close friends or family. This nostalgic yet somewhat obscure tradition still survives in Japanese culture, and this news report examines why it continues to endure.

In Japan, such distinctive and symbolic customs related to school life have a prominent place in societal and cultural discussions. The tradition of gifting the second button is often romanticized in popular media and seems to hold a nostalgic value, especially amongst the older generation. As it is tied to youth and graduation, it also leads to discussions about the rapidly ageing society in Japan, evoking a sense of longing for the fervour of youth.

In the US or EU, there are some similar rites of passage traditions surrounding graduations such as yearbook signings or exchange of class rings. However, there isn't a directly comparable tradition to Japan's second button practice. This shows the unique cultural characteristics of Japan that reinforce social bonds and traditional norms.
