Do Japanese people celebrate their sweet sixteen?

In Japan, the concept of a "sweet sixteen" celebration is not traditionally observed as it is in some Western cultures. However, turning 16 can be acknowledged through various personal or family gatherings, but these are not formalized celebrations like a sweet sixteen party. Instead, significant coming-of-age celebrations in Japan occur at age 20, known as "Seijin Shiki," which marks the transition into adulthood.
