Tonbo") is a Japanese manga series written by Ken Kawasaki and illustrated by Yū Furusawa [ja].

[1] A retired golfer, Kazuyoshi Igarashi, arrives there and finds Tonbo Ōi, a junior high school girl with a talent for golf.

[16] The company also streamed the first season of the series on Amazon Prime Video with an English dub, releasing it simultaneously as it aired in Japan.

Rebecca Silverman felt it did "an excellent job of establishing its setting" and using the island's "casual golf culture" to display Igarashi's "presumptive past golf-related trauma", but was critical of Tonbo being portrayed more as a "non-character than a person" during her debut.

Nicholas Dupree was critical of the leads not being either "engaging or interesting" to entice viewers and felt the overall production had the "hallmarks of a long-running show with modest resources and modest-er vision", giving note of the "inconsistent, flat character art and a good amount of reused footage" throughout the runtime.

The fourth reviewer, James Beckett, criticized the "stale characters" and the overall visuals coming across like "three people animated it on a budget of loose change and broken dreams", saying "the end product is so stiff and lifeless that I felt like I may as well have just been looking at the manga anyway, except with more color and an annoying soundtrack that I didn't ask for.

"[25] Taylor chose the first season as his pick for the Worst Anime of 2024, criticizing the overall pacing, one-note supporting characters, bland direction of its golfing scenes, and not being "worth the investment" to check out the second season, concluding that: "If there's one thing worse than being terrible, it's being boring, and while there are certainly other shows this year that had bigger problems, this one was by far the biggest slog.

"[26] Taylor reviewed the first episode of the second season, criticizing the first half for its pacing and "overly technical explanations" but praised the second half for the introduction of Hinoki and the potential of "an actual ensemble" alongside Tonbo and Igarashi, concluding that "if you are someone who's kept up with the series and enjoyed everything about the first season, then this certainly seems like it'll be more of that, and you'll probably have a decent time.

[28] While critiquing about the "overblown and silly" display of golf and the "otaku-level details", she praised the plot's exploration into the mental game of the sport through its players' development and the improved animation from the previous season.
