Wota ( ヲタ ) is a Japanese subculture dedicated to celebrating idols, both real and fictional. It is a form of Otaku and the name is derived from Wotaku , the katakana form of Otaku. Wota also carries some negative connotations of being obsessive, like Otaku. While it originally was mainly associated with men, there has been a rise of female wota since the mid-2010s as part of the diversification of idol culture.

Wotakatsu (ヲタ活) are all general activities done as part of the subculture such as going to concerts, attending events, and buying the latest releases or merchandise. Even if you don't have the chance to partake in anything "live", exchanging with others about your favorite idol groups on social media is a great way to meet other wota.

Oshikatsu (推し活) refers to all activities related to celebrating your favorite idol (oshi). In addition to idol group members and actors, this can also include fictional characters. The activities of oshikatsu are wide-ranging and there are various ways to enjoy them, but the most popular is crafting goods that promote your favorite with the most popular being ita bags.

Nuikatsu (ぬい活) centers around small dress-up plushies in "chibi" style of one's favorite characters or idols. The appeal of the activity is that it can be enjoyed by a wide range of people in the form of the creation of the plushies as well as creative photography. Since a boom in the mid-2020s, there is many tourist destinations offering own photography spots specifically for nuikatsu.

Wotagei (ヲタ芸) is a dance involving glow sticks made by the audience in support of the performing idol group.

Ryousangata Wota (量産型ヲタク) is derived from the observation that female wota are known for posting pictures of themselves attending live events dressed in elaborate Girly Kei outfits, often to the point where many of them look seemingly identically in groups. This has caused many to call wota girls "ryousangata" (量産型), or "mass-produced", in reference to their fashion taste.
