Since 2011, Rokudenashiko has been using her own Manko(vagina) as a motif for her works, such as Deco-Manko and Diora-Manko. However, the size of the Manko is only the same as a palm of your hand. Even if she were to hold an exhibition, she would have to make a large number of them to fill the venue. She want to make bigger and more impactful Manko works! In 2013, Roudenashiko set up a crowd fund to create a Manko kayak(giant vagina boat) by converting her own Manko into 3d data. Contrary to initial expectations, 100 man-yen（exchanged into euros is 7500 US$) was raised, and the first Manko kayak of the century was successfully completed and unveiled on the Taman-gawa (Tama River). At the unveiling ceremony, Manjiru (pork miso soup) was served and the Manko kayak with Roudenashiko on board paddled out to the open sea as supporters watched warmly... However, at this time, sending 3d Manko data as a return to patrons was deemed a crime, and in 2014 Rokudenashiko was arrested on two separate occasions.
