en.wikipedia.org/wiki/Keiji_Nakazawa

The article itself earlier says Nakazawa portrayed his experience in the 1972 story Ore wa Mita (おれは見た). External bibliographic sources confirm that chronology.

• LinguaHiroshima’s bibliographic entry for I Saw It: The Atomic Bombing of Hiroshima, a Survivor's True Story lists the English translation as: Seattle, Educomics, 1982.
• The same entry separately lists the original work おれは見た by Nakazawa Keiji as: Tokyo, Shueisha, 1972.
• WorldCat also catalogs I saw it : the atomic bombing of Hiroshima, a survivor's true story as an English print book published in 1982 by Educomics.

So the date 1982 does not match the original Japanese work named in the entry (おれは見た / Ore wa Mita); it matches the later English translation. A correct entry would distinguish the original 1972 Japanese publication from the 1982 English edition.
