Haru to Gen Anime Premieres January 4, 2027: Cast and Teaser

When does Haru to Gen premiere?

Haru to Gen premieres in Japan on Monday, January 4, 2027. AnimationID announced the first broadcast date on October 21, alongside the opening of the anime's official website, a teaser and its main cast.

The Japanese title is Haru to Gen: 70-sai, Hajimete no Kosodate, a story about beginning childcare at 70. Unlike an announcement that gives only a season or month, this update provides a specific day and a local television slot.

Where can you watch it?

The confirmed broadcaster is tvk / Television Kanagawa, with episodes scheduled on Mondays at 21:55 Japan Standard Time. That is a Japanese television schedule. It should not be treated as an international streaming launch time. Related reading: The Fledgling Demon Lord's Starter Shop Anime Premieres January 2027.

The official site lists its streaming section as coming soon. No international platform or English dub release has been confirmed in the sources checked for this report. Viewers outside Japan should therefore wait for a distribution announcement before assuming the series will appear in their local catalog.

What is the story?

Gen is a rigid, work-focused man who has lived alone since his marriage ended. At 70, he takes responsibility for his three-year-old granddaughter Haru following the death of his daughter Sakura. Raising a child forces him to confront a family role he neglected earlier in life. Related reading: The Otome Heroine's Fight for Survival Anime Premieres July 2027.

The premise follows the daily adjustments of two people with very different needs: an older man learning how to care for someone and a small child bringing energy into his isolated routine. The official introduction presents their relationship as a warm family story shaped by loss and a new beginning.

Confirmed Japanese voice cast

• Bin Shimada as Gen.
• Hiromi Igarashi as Haru.
• Mayuko Kazama as Sakura.

AnimationID says additional cast information will follow. The three names above are the confirmed main roles in the October 21 announcement; they are not an English dub cast. Related reading: Red Riding Hood: A Detective Story Premieres January 2027 on Crunchyroll.

Who is making Haru to Gen?

The adaptation is based on Yuka Oshima's comic and is directed by Kodai Sato. The official credits list music by bermei.inazawa and animation production cooperation by Studio Nanahoshi, within the AnimationID project. This wording preserves the production roles rather than assigning every part of the adaptation to a single studio.

Watch the official teaser

AnimationID has released a short promotional video introducing Gen and Haru. The official announcement links directly to the video below; it is a teaser for the adaptation, rather than a full episode.

What to check before January

The first Japanese broadcast date is established, but international streaming, subtitle languages and dubbing plans still need separate confirmation. The television schedule is also subject to change, as the official site notes. Keep the local Japanese time separate from any future service-specific release time.

Official sources and more upcoming anime

The date, main cast and teaser come from AnimationID's October 21 announcement. The official anime website provides the story, credits and on-air information. Browse our anime release calendar and latest anime news for other confirmed premieres.

Can you read the original manga before the anime?

The anime adapts Yuka Oshima’s manga. KADOKAWA’s official listing identifies Volume 1 as a 184-page comic essay released in Japan on March 28, 2024. Its synopsis describes Gen living alone after his divorce before being entrusted with Haru, the young daughter of his estranged child; at 70, he faces parenting for the first time and discovers that daily life with a child is unpredictable. The listing gives readers a route to the source material and explains why the adaptation begins with a family handoff rather than a newborn. It does not confirm how many volumes or chapters the January anime will cover, and this Japanese listing does not establish an English-language edition. See KADOKAWA’s Volume 1 listing.

What tone and format should viewers expect?

AnimationID’s official website includes comments from the three main voice actors. Bin Shimada, who plays Gen, describes it as a short drama with installments of about three minutes, and says it balances comic childcare mishaps with emotional moments. Hiromi Igarashi describes Haru as energetic and strong-willed; Mayuko Kazama points to the gradual closeness between the two characters. These are performers’ comments, not a full genre label or episode guide, but they offer useful context: the hook is everyday caregiving, with grief and family repair in the background. Treat the approximate runtime as cast commentary; the confirmed program listing still gives the tvk Monday slot and warns that broadcast times can change. It does not supply an international streaming date or a complete episode schedule. Read the official staff and cast comments.

Why the age gap matters to the premise

The full Japanese subtitle, “70-sai, Hajimete no Kosodate,” points to the central contrast: Gen is beginning childcare at 70, while Haru is three. The official introduction frames this as a family story built around two people adapting to a new routine after Sakura’s death. That description supports a caregiving and second-chance reading, but it does not establish how every family conflict will resolve. The confirmed synopsis is enough to explain the unusual setup without turning it into a promise about later episodes.
