Kibyōshi (黄表紙?) is a genre of Japanese picture book kusazōshi (草双紙) produced during the middle of the Edo period, from 1775 to the early 1800s. Physically identifiable by their yellow-backed covers, kibyōshi were typically printed in 10 page volumes, many spanning two to three volumes in length, with the average number of total pages being 30.  Considered to be the first purely adult comicbook in Japanese literature, a large picture spans each page, with descriptive prose and dialogue filling the blank spaces in the image.
Due to the numerous characters and letters in the Japanese language, moveable type took longer to catch on in Japan; it was easier to carve the text directly onto the same wood block as the illustration.  This allowed for a close and harmonious interaction between image and text , with either a balance of both elements, or text dominating the image . Kibyōshi used kana-based vernacular language. Known for its satirical viewing of and commentary on flaws in contemporary society, these books focused primarily on urban culture, with most early works writing about the pleasure quarters. Typically, kibyōshi were printed with 10 pages in a volume, with the average number of total pages being 30, thus spanning several volumes. 
While the kibyōshi may have only been popular for a short period of time, thousands of pieces were published. At its peak in 1784, a record of 92 titles were published.  Only a fraction of this genre has been studied, leaving much to still be written.
Uda Toshihiko divides the history of kibyōshi into five periods: the incipient pieces (1775-1779), early works (1780-1783), gossip pieces (1784-1787), protest pieces (1788-1790), and post-Kansei Reform works. 
The first major kibyōshi to be published was Kinkin sensei eiga no yume, often translated as Master Flashgold's Splendiferous Dream, by Koikawa Harumachi in 1775. It combined the wit and subject matter of fashionbooks with the graphic nature of the otogizōshi to retell the classic noh drama Kantan in contemporary Edo. Harumachi started with a prologue, which was common in fashionbooks but virtually nonexistent in otogizoshi. The piece featured realistic dialogue, trendy language, contemporary slang, and modern fashion trends. Through Master Flashgold, Harumachi created not only a new genre but a new market entirely; 50 to 60 kibyōshi titles are estimated to have been published in the next 2 to 3 years alone. Initially, print runs were limited, but the high demands lead to the number of copies per run, as well as the number of titles per year, to increase.Another noteworthy piece released by Harumachi during this early phase of kibyōshi was Travelogue of Snooby Atlier (Kōmansai angya nikki), which he released the following year in 1776.
Continuing his success, Harumachi released many more successful kibyōshi. Other authors were keen to follow his lead, including Santō Kyōden, Shiba Zenkō, Ōta Nanpo, and Hōseidō Kisanji, who all got their start during this period. Kisanji's Dreamers the Winners (Miru toku issui no yume) threw him into the popular literature spotlight when published in 1781. Early kibyōshi targeted an educated audience, as evidenced by allusions made to “old fashioned” theatre, such as noh and kyōgen, in Master Flashgold and Travelogue and kabuki being used as a major plot point in Dreamers. 
Golden age of gossip pieces
Kibyōshi published during this time were riddled with countless references to contemporary persons, places, events, etc. The pieces from this period were composed of nine parts social satire and one part political satire. Kyōden's Playboy, Roasted à la Edo (Edo umare uwaki no kabayaki, 1785), for example, alludes to modern kabuki actors, authors, poets, and courtesans. It contains political overtones regarding the class system, as the protagonist Enjirō tries desperately to live the life of the romantic heroes of kabuki plays and ballads, despite being a merchant's son; he is firmly put back in his place at the end of the story. Other popular titles of the day include:
- Pat-a-cake! Pat-a-cake! (Atama tenten ni kuchi ari) by Ōta Nanpo (1784)
- Horned Words of a Dishheaded Demoness (Hachikazuki hannya no tsuno moji) by Kyōden (1785)
- Absent White Lies (Teren itsuwari nashi) by Ōta Nanpo (1786)
Political satire of “protest pieces”
Piece from this era reversed the proportion of the gossip pieces to nine parts political, one part social. These kibyōshi were written during an intense period of social unrest; Japan was afflicted with natural catastrophes, such as floods, volcanoes, cold weather, earthquakes, and draught, leading to high commodity prices as famine struck the country, causing an estimated one million citizens to starve to death.  Additionally, government corruption, fiscal mismanagement, and the threat of class wars were plaguing the nation. These protest kibyōshi reflected the popular sentiments, but these messages were never outright said, in order to get past censors. Instead, the authors used a number of literary devices, such as allegory, asides, and reductio ad absurdum to code their true messages.  The key to the satire of this period was overtone rather than overt statements. Popular subjects to satirize included the Tokugawa regime, bad blood between Tanuma Okitsu and Sono Zanzaemon Masakoto, devaluation of the silver coin, and Neo-Confucian policies advocated during the Kansei Reforms, based on a sampling of major works.  While never proven, it is likely that these novels contributed to public outrage and violence.

Post-Kansei Reforms works
In 1791, strict censorship laws ended political satire in kibyōshi. Kibyōshi was prohibited from touching on current events and politics. All printed material had to be approved by government appointed censors; printblocks had to be submitted to a censor and had to be stamped “inspected before the piece could go to print. Additionally, all publications had to clearly state the names of the author, artist, and publisher, to prevent unapproved material from being produced. The government also reprimanded authors of the protest pieces, and by 1791 virtually no one had gotten by unscathed. The first to be punished was Hōseidō Kisanji. It is said he was ordered to disappear from Edo, by means of a forced exile. Koikawa Harumachi was summoned, but he declined to appear on medical ground. He ultimately avoided having to present himself by dying abruptly; rumors of a self-imposed death spread. Ōta Nanpo unexpectedly gave up writing and disappeared under the radar. Publisher Tsutaya Jūzaburō had half of his assets confiscated; he was arguably the most influential publisher of popular literature and art of his time. Kyōden, undisputedly, was reprimanded most severely. He was brought before the City Magistrate and was forced to recant. He was then shackles and put under house arrest for 50 days. Despite punishment, he continued to publish kibyōshi for 15 years, minus the political overtones. He also released what is considered one of the last masterpieces of the genre, The Night Before Rosei's Dream (Rosei ga yume sono zenjitsu, in 1791. It was written and published after the admonishments of Kisanji, Nanpo, and Harumachi, but before he himself was preosecuted.  The last major author to be punished was Shikitei Sanba. His piece Swaggering Headbands: A Chronicle of Urban Knight-Errantry in a Peaceful Realm (Kyan taiheiki mukō hachimaki, published in 1799, actually incited physical violence. An Edo fire brigade assailed his residence, as well as the residence of his publisher, ironically enough in protest of the negative portrayal of fire brigades in his story. Due to censorship, works after 1791 lacked the playful spark of earlier kibyōshi.  Without political and social satire as fodder, authors were forced to go back to parodying earlier kibyōshi and other written formats, which grew tedious fast.
End of kibyōshi
Many scholars agree that the end of the genre came in 1806, though individual pieces continued to trickle out until as late as 1828. While the Kansei Reforms certainly damaged the industry, it is believed this was not solely responsible for the disappearance of the kibyōshi, but rather that it just sped up the process. What really killed the genre were the constant attempts to broaden the reader base by appealing to a wider audience.  Initially, kibyōshi was written by educated authors for educated individuals. As authors attempted to expan the reader base across different classes and education levels, the jokes, illusions, etc. were inevitably dumbed down. As author Adam L. Kern notes, “in bending over backwards to expand its readership, the kibyōshi lost its esoteric uniqueness. In this sense, kibyōshi fell victim to its own success.” 
There are several popular manners in which kibyōshi are translated. One is the method used by James T. Araki in the 1970s, described as an illustrated playscript.  While not perfect, many translators followed his example and used this format. The main concern with this system is that all the text from the image is neatly divided up to a particular speaker, when it's difficult to pinpoint exact speakers in the original test, as the dialogue floats in the empty spaces of the page. Thus, this format gives the misconception that the reading process of kibyōshi is straight forward. It also creates a disconnect between the text and images by taking the text out of the image, making it seems as if the parts are independent of one another when they in fact are interrelated and inseparable. Another common method of translation is to replace the original, hand written text. In the 1920s, Yamaguchi Takeshi replaced the penned text with typescript, but it did not adequately convey the flowing nature of the original script. Suigiura Hinako improved upon this concept when publishing her rendition of Master Flashgold by replacing the sprawling script with her own less curvaceous, more legible handwriting. 
Kibyōshi has its roots in earlier illustrated novels, starting with the companion novels. These lightly illustrated novels would slowly evolve into akahon, or “red books”, the oldest form of woodblock printed comic books. Akahon tended to be easy-to-read adaptations of children's stories, folk legends, and fairy tales. Thus, the next type of woodblock comics, kurohon, or “black books”, feature more complicated retellings of kabuki and puppet plays, heroic legends, and military accounts while still being easy to read. This last genre is from which kibyōshi would directly descend. Early aohon (“blue books”) were almost indistinguishable from kurohon, but this genre can be broken into two distinct categories: works that catered to younger, less literate readers and works that catered to cultured adults. The dyed used to color the covers the aohon faded with exposure to sunlight into various shades of yellow, which is how these sophisticated aohon became known as kibyōshi. It is believe the name change occurred after the hype of the genre, as kibyōshi were referred to as aohon as late as 1802.
