* = Based on the definition of S&H generations being approximately 20-25 years.
** = This can further be divided up into 団塊ジュニア世代 (Dankai Jr. "Boomer Jr." Sedai) (early 1970s) and the rest ポスト団塊ジュニア世代 (Post Dankai Jr. Sedai) (late 1970s-1981)
*** = (As of 2024,) it is generally accepted as someone who was 5 (turning 6) to 19 years old in 2020 (start of COVID-19 pandemic), which likely affected their school years (K-12 and university). According to a 2022 survey from Japanese high school students, they considered themselves as コロナ世代. (However, it won't be confirmed until c. 2032 when all of them are 18 or older to see if this name stays). In the context of working, however, it can be defined as 1998-2006 (age 18-26 in 2024). This is because during the COVID pandemic (2020-2024), they became adults and were in university during part or all of this time period. There is also a chance that this could be the last Japanese traditional generation name because Japanese people are beginning to use the English generation names (e.g., Z世代・α世代).
**** = Based on GenWHY generations ranging approximately 20-22 years.
