About the exhibition

The Genga’ (Dash) project has been organized by manga artist Takemiya Keiko and Kyoto Seika University International Manga Research Center to preserve and make a good use of original manga drawings, which can fade easily.
To celebrate the project’s 20th anniversary in 2021, we organized an exhibition with new Genga’ (Dash) that are based on original drawings of four artists: Higashiura Mitsuo, Asuka Sachiko, Sasaya Nanaeko and Tadatsu Yoko.

The beautiful and detailed works have moved readers in the past. Through Genga’ (Dash), the power of the works is being revived and is touching people’s hearts again.
150 pieces of Genga’ (Dash), including the project supervisor Takemiya Keiko’s works, will be on display with related magazines and books. Also, some original drawings of Sasaya Nanaeko will be showcased side by side with Genga’ (Dash).

Higashiura Mitsuo


After working as a toy designer and Kamnishibai(Japanese style picture show) artist, Higashiura changed his job to manga artist because of Tezuka Osamu’s suggestion. He debuted as a manga artist with “Gekko no kenshi”, an Akahon (cheaply printed manga books at that time). He first worked on some Akahon and rental manga books. Then around 1954, he started to work for shojo manga magazines, such as Shojo, and Shojo Club as well. His manga, for instance “Kinoko-chan” and “Osuzu-chan”, fascinated many girl readers by using very active heroines on adventure. Higashiura passed away in 2012.

Asuka won the 4th Kodansha shonen shojo manga prize with “100ninme no boyfriend” when she was in her second year of high school. She debuted with the same title on Weekly Shojo Friend in 1966. Her representative works, such as “Kaido Komori hakushaku”, “Shiroi Line” and “Frederica no asa” were full of wit, unlike most shojo manga at that time. Her manga style was considered pioneering and it attracted numerous readers. After working for shojo manga magazines and children’s magazines in the 1980s she started a new carrier as an illustrator and is still actively working.

About Genga’ (Dash)

What is Genga’(Dash)?

A Genga’ (Dash) is an elaborate reproduction of an original manga drawing. It is almost indistinguishable from the original even when they are beside one another, since everything including subtle differences are reproduced, such as shades in linework and detailed color gradation. Takemiya Keiko, the former president of Kyoto Seika University, and author of manga titles such as “Kaze to ki no uta” (The Poem of Wind and Trees) and “Terra e…” (To Terra…), has led the project in the development of techniques to aid in the preservation and public exhibition of delicate manga drawings which can easily be damaged by fading. The project started in 2001 under the idea of “archiving original manga drawings as they are, including damages and stains”. In 2021, it marks the project’s 20th anniversary.

How are Genga’ (Dash) different from other reproductions?

The biggest difference is that Genga’ (Dash) are produced to archive all information that original manga drawings have at the moment. Usually, reproductions are made by erasing damages or stains and adjusting colors, so it can be more colorful. However, Genga’ (Dash) is made by scanning the originals and reproducing the condition of papers, stains and scratches. It is because we think that every trace on the original drawings is a precious part of understanding the time period and the background of the artists’ work. This is why we named it “Genga’ (Dash)”, which means “an original drawing in another form”, instead of a reproduction.

When are Genga’ (Dash) useful?

Recently manga is gaining attention both within Japan and abroad and the number of manga exhibitions is growing. It is not unusual these days for manga to be exhibited. However, there is always worry that the original drawings may suffer damage or loss. Manga drawings are delicate by nature and are not created for display, thus even short exhibitions can result in color fading. Accordingly, the Genga'(Dash) exhibitions act as an effective measure for preservation. Genga'(Dash) are resistant to both light and water, allowing for exhibitions in venues and for time lengths that would otherwise be impossible. The artist may even rest assured that they can safely be lent overseas without fear of the originals becoming lost in transit.

Process of making Genga’ (Dash)

The production of Genga’ (Dash) starts with scanning original drawings in the actual size. Then, with image processing software, we adjust colors and texture of the scanned data, so it looks exactly like the original drawing, by comparing the data and the original. After that, we print the data and compare the printed one with the original, and, adjust the data again if there are any differences. These processes are repeatedly done with Takemiya Keiko, the supervisor, and Dai Nippon Printing, a Japanese printing company, as research partners. Depending on the type of the drawing, whether it is full-colored or black and white, different methods for adjusting the shading are needed. In general, the order of adjustment is: ①color of the paper→②characters’ skin and hair colors→③other details. It takes time and effort to reproduce particular features of manga drawings, such as color irregularities, dialogue written by a pencil, monochrome screen tone, and pasted typesetting inside speech balloons.

Activities of Genga’ (Dash) in Japan and abroad

As Genga’ (Dash) are indistinguishable from the originals and can stand long exhibition periods, they have been playing an active role in exhibitions in Japan and abroad.
Please check out a part of activities of Genga’ (Dash) in pictures and a video below.

「Shojo Manga! Girl Power!:What can shojo manga tell you?」展

Exhibition “Shojo Manga! Girl Power! : What can shojo manga tell you?” (2005-2007)

This exhibition started in Chico in California and traveled to 11 cities in North America. A part of the exhibits in the exhibition were Genga’ (Dash). In 2008, a renewed version of the exhibition was held in 4 places in Japan.

「L’univers des mangas pour adolescentes」展

Exhibition “L'univers des mangas pour adolescentes” at Pompidou Center in Paris, France (2012)

This exhibition was planned to introduce the history of shojo (girls’) manga through Genga’ (Dash) of 14 artists who represent shojo manga.


Exhibition “MANGAMANIA” in Augustusburg castle in Germany (2017)

This unique exhibition in the historical castle was organized to introduce Japanese popular culture, including manga. 10 Genga’ (Dash) pieces of Watanabe Masako, one of the most influential shojo manga aritsts, were showcased in the exhibition. Due to popularity beyond imagination, the exhibition period was extended, and in the end, the exhibition was held for over a year. It is no exaggeration to say that it was a chance to show the durability of Genga’ (Dash).

「原画’(ダッシュ)で見る 昭和の少女マンガ」展

Exhibition “Genga’ (Dash) de miru Showa no shojo manga” at the Museum of Fragrance, Iwata (2018)

With the theme of shojo manga from the Showa era (1926-1989), around 80 Genga’ (Dash) pieces of nine manga artists were showcased in the exhibition. It is not always easy to gather several artists’ manga in one place. However, it worked out well for this exhibition because Genga’ (Dash) are collected and managed by Kyoto Seika University International Manga Research Center and Kyoto International Manga Museum.

「L’univers du shojo manga」展

Exhibition “L’univers du shojo manga” in Alsace, France (2019)

This exhibition was organized by European Center for Japanese Studies in Alsace with support of the prefectural assembly of Haut-Rhin. About 70 pieces of Genga’ (Dash) were on display at the exhibition. One of the exhibition venues was the assembly hall of Haut-Rhin, and the hall was not a great place for an exhibition since there was some sunlight inside of the building. However, we were able to realize our goals for the exhibition perfectly thanks to Genga’ (Dash).

「The Citi exhibition Manga」展

Exhibition “The Citi exhibition Manga” at the British Museum in London, the United Kingdom (2019)

The manga exhibition received attention from all over the world since it was organized on the largest scale for a manga exhibition held outside of Japan. In the exhibition, there was a section to introduce the goal and significance of Genga’ (Dash) and some Genga’ (Dash) were also on display.


Exhibition “Shojo Manga -An Introduction-” at the Japan Foundation, New Delhi (2020)

This exhibition was organized by the Japan Foundation and all of the works on display were Genga’ (Dash). At the middle of the exhibition period, the exhibition was suspended since a nationwide lockdown was ordered in India due to COVID-19. However, it did not cause any significant problems, since Genga’ (Dash) were showcased instead of original drawings.

※Even besides the examples above, Genga’ (Dash) have been on display in number of exhibitions and events. If you want to loan Genga’ (Dash), please contact us.
