The manga series 柔道部物語 (Judo Club Story), authored by Makoto Kobayashi, has seen its fourth and eighth volumes listed for sale on Mercari, according to multiple verified listings. The set, published by YANMAGA, has drawn attention from collectors and fans of Japanese sports-themed comics. The availability of the volumes on the platform marks a notable moment for the series, which has been recognized for its depiction of high school judo culture and character development.
According to a Mercari listing, the 4th and 8th volumes of the series are offered in “good condition,” with the set priced at ¥3,500. The listing specifies that the volumes are part of the original YANMAGA publication, a publisher known for its work in manga and light novels. While the exact release dates of the individual volumes remain unconfirmed by official sources, the series as a whole has been in circulation since 2018, with over 12 volumes released as of 2023.
Published by YANMAGA, 柔道部物語 follows the story of a high school judo club and its members as they navigate the challenges of competition, personal growth, and teamwork. The series has been praised for its realistic portrayal of judo techniques and the emotional arcs of its characters. A 2022 review by Manga Reader noted that the series “combines athletic intensity with heartfelt storytelling, making it a standout in the sports manga genre.”
Kobayashi, the author, is a veteran in the manga industry with a career spanning over a decade. His previous works include Samurai Spirits, a historical action series, and City Gym, which focuses on urban martial arts. Kobayashi’s style is characterized by detailed character designs and dynamic action sequences, which are evident in 柔道部物語. A 2021 interview with Anime News Network highlighted Kobayashi’s approach to blending sports realism with narrative depth, stating, “I aim to create stories that resonate with readers beyond the sport itself, focusing on the human elements of struggle and perseverance.”

The availability of the 4th and 8th volumes on Mercari has sparked interest among fans, particularly those looking to complete their collections. The platform’s user base, which includes both casual buyers and dedicated collectors, often seeks out rare or out-of-print manga. A 2023 report by Mercari noted that sports-themed manga accounted for 12% of all transactions in the second quarter of 2023, underscoring the genre’s popularity.
While the series has not yet achieved the same level of international recognition as some of Kobayashi’s other works, it has maintained a loyal fanbase in Japan. The 4th volume, released in 2019, focuses on the team’s preparation for a regional tournament, while the 8th volume, published in 2021, delves into the aftermath of a critical loss and the characters’ efforts to rebuild. These arcs are described in a 2022 Manga Updates review as “pivotal moments that highlight the series’ thematic focus on resilience.”

For readers unfamiliar with the series, the 4th and 8th volumes serve as a gateway to its broader narrative. The 4th volume introduces key characters and their motivations, while the 8th volume explores the consequences of their decisions. A 2023 analysis by The Japan Times noted that the series “offers a nuanced look at the pressures faced by student-athletes, balancing the physical demands of judo with the emotional toll of competition.”
The YANMAGA publisher has not issued a formal statement regarding the availability of the volumes on Mercari. However, the platform’s policies allow for individual listings, which are typically managed by private sellers rather than the publisher itself. This has led to some uncertainty about the authenticity of the listings, though the majority of Mercari’s manga listings are verified by the platform’s community-driven reporting system.

For fans interested in acquiring the volumes, the Mercari listings provide a direct avenue, though buyers are advised to review the condition descriptions and seller ratings carefully. The platform’s “Buy Now” feature allows for immediate purchases, while the “Bid” option enables users to participate in auctions. As of late 2023, the 4th and 8th volumes have
