Insights shed light on international use and popularity of digital manga outside Japan

UPDATE 10/14/20: We have updated the article for further clarity.
The editor for Shueisha's Manga+ (Manga Plus) smartphone application, Yūta Momiyama took to his personal Twitter account recently to share insights and observations on the popularity of the Manga Plus smartphone app, which is frequently lauded for its worldwide availability. Momiyama detailed the popularity rankings for the top twenty countries which had the most readers who used the service, listed below:
1. USA
2. Thailand
3. Indonesia
4. Mexico
5. Philippines
6. Spain
7. Malaysia
8. Brazil
9. Peru
10. Germany
11. Italy
12. Argentina
13. Chile
14. Colombia
15. France
16. India
17. Canada
18. UK
19. Vietnam
20. Singapore
Another observation Momiyama made was centered on the popularity of serialized titles that currently do not have anime adaptations. Wheras previous Jump serials suffered from nonexistent international popularity without an anime adaptation, one of the most popular titles on the app in SpyxFamily is frequently at the top of in-app readership with every new chapter released, currently without such a tie-in.
He further speculated that the strength and popularity of the title was due to it being more compelling than the typical manga and the absence of illegal scanlations or leaks for it. Finally, he also mentioned that every time a new chapter for an especially popular title is released on the app, the reader count "swells to a million readers following on a legal platform" observing how popular titles grow substantially in popularity with every new chapter and the ease of international access can make a real difference.
