What is Toshishita Seme (年下攻め)?

Toshishita seme refers to seme characters that are younger than the uke they are dating or wooing. It often overlaps with other seme character tropes such as supadari and wanko seme. In general, the word itself is used to refer to younger seme characters.



The word toshishita seme is written as 年下攻め and has a fairly straightforward meaning. The word 年下 (“toshishita,” literally “younger”) is combined with the word 攻め (“seme,” translates to “attack,” “offense”). The word’s literal meaning is “younger seme,” a rather convenient word to categorize BL stories.


Brief History

It isn’t a stretch to say that BL genre’s standards were already quite defined during the late 1990s: domineering and proud seme characters with a bit of an attitude problem paired with loud and a little selfish uke characters who wholeheartedly accept the seme. 

In the early 2000s, however, a new variation of BL began to gain some popularity. This not-quite genre is known as あんた呼び (“anta yobi,” referring to the uke calling the seme “anta,” which is often considered coarse but at the same time only used to close people). Anta Yobi series frequently depict a toshishita seme, which is often also a wanko seme, slightly obsessed or extremely devoted with the uke. These BL series brought about the wave of BL portraying toshishita seme characters. 

Along with the new wave BL genre, around the 2005 series depicting toshishita seme characters began to snag the spotlights and enjoyed a considerable rise in popularity, especially BL with a school setting. Such can be seen with Koisuru Boukun by Takanaga Hinako and Seito Kaichou ni Chuukoku by Monchi Kaori. Since 2013, toshishita seme BL has become another popular BL standard, and publishers use this character trope for categorizing and marketing purposes.


Toshishita Seme: Modern Usage

As the BL genre and its rapidly expanding variation of sub-genre grow and diversify, so do BL stories with toshishita seme characters. While the devoted, puppy-like toshishita seme is still extremely popular, as proven by Dakaretai Otoko 1-i ni Odosareteimasu’s massive success, other types of toshishita seme character trope are also very popular. For example, BL light novels popularized the do-S type of toshishita seme character, which later paved the way for series like Ten Count by Takarai Rihito to become a hit. 

Most noticeable, however, is the variety of uke types paired with toshishita seme. In the beginning, it was common to see tsundere slightly hot headed and extremely beautiful uke paired with toshishita seme characters. Recently, we have seen more varied uke types being paired with toshishita seme characters. The different personalities of the uke have little impact in changing the original appeal of toshishita seme BL. A relationship dynamic in which the older uke can also dominate the younger seme is just as good because of the uke‘s life experience and maturity.
