Heisei Retro
Heisei retro (平成レトロ) is a trend of looking back fondly on the objects and design of the Heisei era and deliberately working them into daily life today. Heisei ran from 1989 to 2019, a little over thirty years. Heisei retro mostly covers the first half through the middle of that span, roughly the 1990s through the early 2000s. At the heart of the trend are teens and twentysomethings with little to no memory of the era itself. Everyday objects from before they were born, or before they were old enough to remember, catch their eye as unfamiliar, novel designs. For those who actually lived through the period, meanwhile, the very same objects evoke nostalgia. That contrast in how different generations see them makes them especially likely to spark conversation. It is usually described as one of the retro booms that followed Shōwa retro. English-language coverage uses the same name. Tamagotchi and purikura, the decorated photo sticker booths found in Japanese arcades, are often the way in for people who go on to take an interest in 1990s Japan.
Yume
In otaku contexts, yume ("dream") is an umbrella term for a genre of fan works that depict a relationship between a character from an anime, manga, or game and either the reader themselves or an original character the reader has in mind. For novels it's called yume shousetsu, in illustration yume-e, and in comics yume manga, with the whole category referred to collectively as yume-muke. The original character who stands as the protagonist is the yumenushi, also read yumeshu. Some are self-insert figures the writer or reader maps themselves onto, others are built as a third party kept separate from the author, and there is no fixed template for their appearance or personality. In the narrow sense the word means a story in which the reader can freely replace the protagonist's name. This name conversion mechanism is where the genre began, and many posting sites still support it. People who enjoy yume are called yumejoshi, or yumedanshi for men. Yumejo is also in use, as is dorīmā, from the English word "dreamer". Yume in English-Speaking Fandom The closest concepts in English are self-insert and reader-insert, alongside the widely used Y/N (Your Name) placeholder that stands in for the reader's name. In recent years yume and yumeship have joined them as loanwords, and both are now understood as terms for the relationship between a character and the reader.
Comiket
Comiket (コミケ) is the common name for the doujinshi convention "Comic Market." Doujinshi are self-published books by fans and individual creators. Held at Tokyo Big Sight in the Ariake district of Tokyo, it takes place twice a year, in mid-August in summer and at the end of December in winter. The organizers call it the largest doujinshi convention in Japan. The most recent ones held have grown to a scale that draws a combined 250,000 to 300,000 people over a two-day run. C106, held in the summer of 2025, recorded a combined 250,000, and C107, that winter, a combined 300,000. C106 also drew participants from 71 countries and regions abroad. At the heart of the venue is the sale of doujinshi by their creators, both individuals and the creator groups known as circles. Corporate booths related to anime and games line the hall, and cosplayers gather in a designated zone. Before the doors open, the waiting line stretches outside the building.
Coupling
Coupling (カップリング, kappuringu) is a word used in doujin and fan culture for the pairing of two characters in a romantic relationship. It means roughly what English-speaking fans call shipping. It applies to BL, which depicts romance between men, and to yuri (百合), which depicts romance between women. Male-female pairings work the same way. Shortened, it is written kapu (カプ) or CP. CP is widely used as a shared term among fans across East Asia, particularly in Chinese-speaking communities. An oshi-kapu (推しカプ) is a coupling you personally love and root for. On social media, people use it like "So-and-so and so-and-so are my oshi-kapu." A pairing that the original work presents as a couple is called an official coupling. The word coupling itself is not limited to unofficial interpretations. Even so, what sits at the center of fan activity is the fun of imagining and interpreting pairings that the original never shows. There are spin-off labels too. Pairing a character with themselves is called nijō (二乗), meaning "squared." A bond of friendship or partnership rather than romance is called konbi (コンビ), and to keep it apart from a romantic A×B, it is written A+B or A&B.
Doujin
Doujin (同人) is a word for people who share the same interests or aspirations, and for the groups they form. In otaku culture, it most often refers to the whole range of noncommercial creative activity, where individuals or groups of friends make and release their own works. The best-known form is the doujinshi, a self-published book, but doujin games and doujin music are part of the same landscape. Creators work without publishers or manufacturers, making things at their own discretion and putting them out into the world. All of it rests on the same principle of self-production. The difference from commercial work lies in the order of motives. People create because they want to, not because profit or trends demand it. Niche subjects and experimental styles flourish in doujin precisely because creators are free from sales pressure. Doujin Related Terms A doujinshi is a book made by doujin, a doujin circle is a group that creates together, and a doujin artist is an individual creator in the scene. Doujinshi conventions, with Comic Market (Comiket) as the most famous example, developed as places where creators hand their works out directly to readers. The word covers both original and derivative works built on existing series. Doujin is often equated with fan-made derivative works, but that is only part of what it means.
Nui-katsu
Nui-katsu refers to activities centered on plush toys. It covers everything you might do with a favorite plush or a plush of your oshi (nui), from collecting them and taking them out with you to photographing them and dressing them up. People often describe it as a branch of oshikatsu, the activities fans do for their oshi, but having a particular oshi is not a requirement. Heading out with a plush you fell for at first sight, or one you have kept close for years, and changing its outfits counts as nui katsu just the same. There are many ways to enjoy it. Beyond displaying a plush you have brought home, people carry them along to cafes and on trips to photograph them, which is called nui-dori, and dress them in outfits made for plush toys, known as nui-fuku. Several of these related activities have spread, each with its own term. Getting a new nui is called omukae (roughly to ‘bring home’), and the appeal lies more in enjoying living and going out together than just collecting them. There is no official standard and the names vary, but plushes around 20 cm tend to be used for display, while ones around 10 cm or 15 cm are easier to carry around. Outfits for changing clothes are also easy to find in the latter two sizes.
