Yuko Natsuyoshi: Voice of Yani in Chainsmoker Cat

The official cast credits Yuko Natsuyoshi as Yanineko, written ヤニねこ, whose Japanese personal name is 佐藤ヤニ子.

Yuko Natsuyoshi is the Chainsmoker Cat voice actor for the main character. The character profile lists Yanineko as a 21-year-old beastfolk lead.

Episode 1 moves the role through rent trouble, work, family pressure, and the condition of Yanineko's room, connecting the cast credit to the story rather than leaving it as an isolated name.

For the official name, age, relationships, and Episode 1 context, visit the Yanineko character and voice actor guide.

In comments published by the official anime site, Natsuyoshi describes the appeal of turning a heavy smoker's daily life into a cat character and notes the specificity of the smoking-related comedy.

She also emphasizes the contradiction at the center of Yanineko: the character is extremely dirty and repeatedly crosses social lines, yet still appears strangely cute. That contrast helps explain the performance tone without adding an unsupported biography of the actor.

The comments concern the Japanese performance and character impression. They do not confirm a dub, regional audio track, or separate performer for another language.

The Episode 1 recap follows the first set of Yanineko, Imoko, and Otani scenes.

The credit answers a specific question: who performs Yanineko in the original Japanese cast. It pairs Yuko Natsuyoshi with the character alias ヤニねこ and the official Japanese personal name 佐藤ヤニ子, so the result can be checked against both the cast and character pages.

Yanineko, 佐藤ヤニ子, and Yaniko Sato do not carry the same evidence label on this guide. Yanineko is the character alias used by the anime; 佐藤ヤニ子 is the official Japanese personal name; Yaniko Sato is the English rendering used here to make English-language searches easier to follow.

That distinction is useful for searches such as “Chainsmoker Cat voice actor” or “Yuko Natsuyoshi Chainsmoker Cat.” It leads back to a named official role rather than relying on a copied database row or a search snippet with no source context.

For a viewer starting with the premiere, the credit also provides a practical route through the site: identify Yuko Natsuyoshi here, confirm Yanineko's official Japanese name in the character profile, then use the Episode 1 guide for the events that introduce her.

The Yanineko profile keeps the official name, age, first appearance, and character context together.

A Japanese cast credit identifies the original performer and role pairing. It is the right evidence for who voices Yanineko in the Japanese anime, but it is not a biography of the performer and it does not establish credits for another language.

Questions about subtitles, dubs, and audio tracks belong to the licensed service and the region of the account being used. A streaming page may carry the series while displaying a different set of options from another country, so the player is the final check for language availability.

For the wider ensemble, the official cast page lists the Japanese role pairings. For one character's relationships or first story appearance, the corresponding character profile and episode guide give a more useful answer than repeating every cast credit on this page.

Use the legal watch guide when the question is about a service or an audio option.

Misato Matsuoka voices Yakuneko, Yurie Funato voices Hameneko, Ayaka Shimizu voices Kansaineko, and Shiori Izawa voices Aruneko.

Rina Honnizumi voices Imoko, Riko Akechi voices Saori, and Tetsu Inada voices Landlord Otani. The official cast list is the reference for names and role pairings.

The complete cast guide keeps those credits beside aliases and episode introductions, which makes it easier to follow the group as the story moves beyond the premiere.

The official staff and cast material confirms the original Japanese role pairing: Yuko Natsuyoshi performs Yanineko, whose Japanese personal name is 佐藤ヤニ子. It is the reliable answer for searches asking who voices the main character.

A Japanese cast credit does not by itself confirm an English dub, a regional audio option, or a separate performer for another language. Check the licensed service player when the question is about the audio choices available to a particular account.

For the character context behind the credit, use Yaniko's profile and the Episode 1 guide. For the rest of the credited ensemble, use the full cast reference rather than a copied list with no episode context.
