Continuing with celebrations this month established by Japanese Internet users, on November 28, the "High Socks Day (II Niihai No Hi) is celebrated", where the artists and the community celebrate the so-called "Knee High (ニ ー ハイ) ", Which are tall socks that remain above the knees. Approximately since 2013, this day has been held annually by the community.
In Japan, there are many unofficial anniversary days, but widely known, designated by companies, organizations, industrial groups or people for their promotion / awareness campaigns, and many of them are promulgated through a simple game of words with the numbers of the Dates, which is due to the characteristic of the Japanese language that Kanji characters that include numbers usually have multiple pronunciations. In addition, anniversary days with word games are usually designated in November because "11" can be read as "I (1) i (1)", which means "good", "nice" or "happy".
In the same way, on November 28, the "High Sock Day" is designated, since the numbers can be read as "1 [I] + 1 [I] + 2 [Nī] + 8 [HA (I)]" , which is the meaning of "good high socks". Meanwhile, the emergence of this day of anniversary did not reach until the end of the 2000s because he inherited a famous "Zettai Ryouiki" concept, or a fetish by the naked leather area in the hole between the stockings above the knee and A miniskirt, which was established in the Otaku culture in the first half of the 2000s. Finally, a wide variety of illustrations can be found through hashtag # いい ニ ー ハイ の 日.
