1) Manga Overview: What Is “Kachō Shima Kōsaku”?
Kachō Shima Kōsaku (“Section Chief Shima Kōsaku”) is the foundational arc of Kenshi Hirokane’s long-running business manga. It follows salaryman Shima Kōsaku at the electronics giant Hatsushiba Electric and portrays realistic meetings, negotiations, and promotions inside a large Japanese corporation. The wider saga tracks his career across multiple roles over decades. Calm, principled, and deft at reading people, Shima advances through corporate politics without bluster—his measured ethics, negotiation savvy, and quietly courageous streak make him an aspirational yet relatable lead.
