Gesshizu (げっしーず) are a group of mysterious iyashikei video game characters, who resemble different rodents and are different colors, but all have prominent front teeth.[1][2] They were created in 2018 as a joint project between the Japanese companies San-X and Nippon Columbia.[3] The name Gesshizu comes from the word rodent. The characters hatch from eggs and are based on rodents like the Japanese dwarf flying squirrel, octodon, and capybara. Between 2018 and 2022 three Gesshizu Nintendo Switch games were developed and published in Japan by Nippon Columbia. One of the games was also released internationally in 2023 by Aksys Games. In 2020 a mobile game app, also by Nippon Columbia, was released. A Gesshizu novelization was published in Japan in 2019, and two different manga series have been serialized in Japanese magazines.
Creation
Gesshizu were created in 2018 as a joint project between the Japanese companies San-X, known for designing characters like Rilakkuma, and Nippon Columbia, who developed and published the Gesshizu games.[3] Shiroi Omochi (しろいおもち), a designer at San-X who previously worked Sumikko Gurashi designs, was involved in the creation of the Gesshizu character designs. The name Gesshizu derives from the Japanese word which means rodent.[4] The suffix zu (ず) comes from the English plural s, and is used to indicate plurality; that Gesshizu are a group.
Characters
Gesshizu are a group of mysterious iyashikei (healing) characters, who resemble different animals and are different colors, but all have prominent front teeth.[5][6] They are depicted as hatching from eggs, with all having the same round shape right after hatching. As they mature they obtain their full adult form and color pattern. The characters, which are mostly based on rodents, include Risu (りす) (squirrel) who is always happy and full of energy, Usagi (うさぎ) (rabbit) who often gets lonely and cries, Nezumi (ねずみ) (rat) who is timid and restless and trembles a lot, Deguu (でぐー) (octodon) who is a leader who brings everyone together, Momonga (ももんが) (Japanese dwarf flying squirrel) who loves cute things, Biibaa (び~ば~) (beaver) who is free-spirited and naps a lot, Hamusutaa (はむすた~) (hamster) who is an easygoing glutton, Yamaarashi (やまあらし) (porcupine) who dreams of being cool, Kapibara (かぴばら) (capybara) who is absent-minded yet dependable, and Chinchira (ちんちら) (chinchilla) who can build anything, and is a character that was added to the third game.[7]
Video games
Three games for the Nintendo Switch have been released, where the player takes care of the Gesshizu. They were all developed and published in Japan by Nippon Columbia.
The first game, Gesshizu: Gajigaji Nakama wo Sodateyou (げっし~ず がじがじなかまをそだてよう) was released in Japan in 2018. It is a virtual pet type game where the player raises the characters from eggs to collect all the different types of Gesshizu.[8][9] It received a score of 28/40 from Famitsu, with reviewers saying the game is cute and soothing, but also repetitive.[10][11]
The second game, Gesshizu: Mori no Chiisana Nakama-tachi (げっし~ず 森の小さななかまたち) was first released in Japan in 2020, and then released internationally in 2023 by Aksys Games, under the title Cuddly Forest Friends, without Gesshizu branding.[12]
