Komajiro is a komainu-type Yo-kai resembling a shiba inu. His ochre fur features cream patches around his muzzle and stomach, darker ochre inner ears and tail, light blue eyes, and brown swirl markings on his cheeks and hips. Long, brown, flame-like eyebrows resembling hitodama flames frame his face, and he carries a distinctive blue pouch adorned with a swirl pattern. As the younger twin brother of Komasan, Komajiro adapts more readily to urban environments. While deeply respectful of Komasan, he exhibits a naturally curious and optimistic personality, quickly embracing modern technology and city culture. This adaptability leads him to adopt city lingo and pursue activities like working as a nightclub DJ under the nickname "KJ," occasionally sparking envy in Komasan over his ease in human society. In the film *Yo-kai Watch: Soratobu Kujira to Double no Sekai no Daibōken da Nyan!*, Komajiro appears alongside Komasan during the initial rainbow light phenomenon caused by the flying whale. He is caught mid-bite eating ice cream in Downtown Springdale when the world shifts from animation to live-action, reacting with confusion to the sudden dimensional shift. This integrates him into the central plot device of world-switching. Across the broader *Yo-kai Watch* media, Komajiro demonstrates electrical abilities in video games, including lightning-based attacks and techniques like "Lightning" (いかずちの術) and the Soultimate Move "Wild Zaps" (風来サンダー), though these combat attributes remain absent from anime or manga. His gameplay mechanics vary: - In *Yo-kai Watch*, he evolves into Komiger at level 35 through standard leveling. - In *Yo-kai Watch 2*, this evolution occurs at level 33. - *Yo-kai Watch Blasters* requires fusion with a Swirly Soul for evolution. He participates in fusion systems, combining with "Komajiro A" to form "Komajiro S" in *Yo-kai Watch: Wibble Wobble*. Komajiro appears as a playable character in *Yo-kai Watch*, *Yo-kai Watch 2*, *Yo-kai Watch 3*, *Yo-kai Watch 4*, *Yo-kai Watch Blasters*, and *Yo-kai Watch Busters 2*. Specific locations vary: typically found behind Rank D Watch locks in Blossom Heights' Old Mansion (*Yo-kai Watch*), under cars or vending machines (*Yo-kai Watch 2*), or obtained automatically during story progression (*Yo-kai Watch 3*, *Yo-kai Watch Blasters*). His statistical attributes and skills differ per installment, often emphasizing speed boosts and electrical attacks.
