"Shimomoku" started out fabricating cosplay costumes in the mid-2000's and began sculpting his own figures around the same time – most notably his series of handmade characters that he called Kinokeshi, releasing his first vinyl toy from the series – "Rampu" in 2013.
Going on Haitus from 2014 – 2017, Shimomoku returned with "Kubita" and "Kabas", which he debuted at the 6th Doki Doki Osaka Sofubi Banpaku event.

Toys are produced within Shimomoku's role at Mitsurin Studios and usually sold via Mitsurin's store – Jungle (ジャングル). Lulubell Toys have also been known to stock various releases in limited quantities. Generally, Shimomoku toy's are hard to very limited and hard to find on the secondhand market – although they do occasionally go up for sale via secondhand retailer Mandarake.

Shimomoku's most notable releases are from the Kinokeshi series,
however multiple other releases and one-offs have been created.
