Uchuu Kyoudai Volume 41 tops the TSUTAYA’s list for the week between May 23 and May 29 at 7 days of sales which should see it sell around 135,000 copies to 145,000 copies when it charts on Oricon’s upcoming sales chart this Friday. Its sales performance has been rough as of late with a continuous decline noted up all the way to Volume 39 before a small recovery is observable between Volumes 39 and Volume 40. To compare, look at Volume 36’s 3 days of sales, and then put it side by side with Volume 38’s 109,625 copies sold in its first 4 days. The series by author Chuuya Koyama first began serialization through Kodansha’s Morning magazine in 2007, and it received a TV Anime adaptation by A-1 Pictures between April 2012 and March 2014 alongside a number of films and OVAs. Its first five chapters can be accessed for free right here in Japanese, however if you would like to check out its official English releases, a preview of its first chapter can be read here for free.
And then, Blue Period Volume 12 is 2nd on the list, also at 7 days of sales with its copies sold expected to reach 80,000 or more amid a boost brought upon its Anime adaptation. The series has already seen growth for its past two volumes which was set before the release of its TV Anime series such as the 3-day sales of 48,931 copies sold for Volume 10, better yet the 5-day sales for Volume 11 at 71,693 copies sold. Compare that to Volumes 7 and 8 which 7-day sales and 5-day sales were only at 46,252 copies and 43,820 copies, respectively. Volume 9 could not chart in its week of release due to intense competition with titles like Jujutsu Kaisen and Kimetsu no Yaiba. As for the title itself, it was first serialized via Kodansha’s Afternoon magazine in June of 2017 with its first chapter readable here for free in Japanese. Kodansha Comics is also publishing the official English versions of the volumes, and the first chapter can be read here for free in English, so do check them out! One more thing, some months ago I remember watching this one video of a Japanese expert who reacted to the series which I find a very good watch. You can check out the video down below (with English subtitles).
All of the data you find below is all thanks to TSUTAYA, one of Japan’s largest bookstores chain which has around 1,200 stores in its local market. You can check out their website here and show them lots of love! Plus, for the week’s chart, you can find it through the link right here. If Google charts are what you are more comfortable with, feel free to visit the respective chart via the link right at the bottom of the post.
Skip over to Number 5 and you will find Vinland Saga Volume 26 at 7 days of sales. The series has not been making any appearances on Oricon sales charts for a while now, having last featured on the Top 30 charts back in 2019 for its 23rd volume. However, its spot on this week’s ranking is already certain, and with its sequel TV Anime adaptation already announced (of which you can check out the announcement video below), we may see a boost in sales. Looking at its 23rd volume performance, I predict it to have between 75,000 copies to 85,000 copies sold. The Manga is also available on Kodansha’s Afternoon magazine which first began its serialization way back in April 2005. You can find its first chapter available for free in Japanese right here. Fret not as its official English version is also being published and feel free to check out its first chapter preview here through Kodansha Comics.
At Number 6 is the Manga adaptation of the Light Novel Hachi-nan tte, Sore wa Nai deshou! with its 11th volume at 7 days of sales. The series’ Manga adaptation has thus far not breached the Oricon Top 30 sales charts, but it has done many times so for its Light Novel. You can check out several chapters of its Manga for free in Japanese through Comic Walker right here which first began serialization in 2015, nearly a year after its Light Novel was published. Kindaichi Shounen no Jikenbo 30th is 7th with its debut volume at 7 days of sales, another spin-off title of the Kindaichi Shounen no Jikenbo series. You can find some of its chapters via Kodansha’s Comic Days magazine right here for free in Japanese.

Arifureta Shokugyou de Sekai Saikyou Volume 10 is 8th on the list with 5 days of sales, its longest so far since its past four volumes were on the charts between 1 to 2 days of sales only. Sales peaked for Volume 7 at 54,581 copies sold in just a day before slowing down all the way to Volume 9. Volume 10 should see a much larger turnout. The series is a Manga adaptation of the Light Novel of the same name which has been serialized in Comic Gardo since February 2016. You can check out several of its chapters for free in Japanese right here. It received a 13-episode Anime adaptation back in 2019 by asread. and White Fox and a sequel was released this year, which aired between January and March.
Finally, two more new titles can be found at Number 16 and 17 with Souzai Saishuka no Isekai Ryokouki Volume 5 having an edge over Sakura, Saku. Volume 4, both at 4 days and 5 days of sales respectively. As for Souzai Saishuka no Isekai Ryokouki Volume 5, it is an adaptation of the Light Novel of the same name, which first began serialization in December 2017 through AlphaPolis Web Manga. You can check out some of its chapters available for free right here. Sakura, Saku. has made several appearances before with Volume 1 at 34,627 copies sold back between May 24 and May 30, 2021, in its first 6 days while Volume 2 was featured this year between January 24 and January 30 selling 34,456 copies sold in its first 6 days as well. This time around, expect its 4th volume to sell slightly less than 30,000 copies. Sakura, Saku. is a Shueisha title authored by Io Sakisaka and is available through the Bessatsu Margaret magazine. You can check out its first chapter preview right here in Japanese (click here for easy access). Shueisha also released a short promotional video to commemorate the 4th volume of which you watch below.
