When one thinks of manga, it is quite likely that your mind will go to the fantastic such as fantasy and sci-fi. However, it is important to remember that manga is a medium like any other and can be used to tell any story. While I’ve spoken about how I think basing media on true stories is overrated, I nonetheless find myself interested in the use of manga to tell true stories (this fascination might stem from how I feel that manga based on true stories is rarer than in other media).
I should probably clarify my criteria for what a manga based on a true story is. In my research on the subject, I saw people bring up historical manga such as Vinland Saga and Kingdom. While it is true that these manga are set in the real world and follow real events, I think referring to them as “based on a true story” gives the wrong idea. Instead, my focus is going to be on manga that tell very personal stories either about the mangaka or about someone else.
