The latest series is titled Sodanyaku Shima Kosaku (Senior Advisor Kosaku Shima/相談役 島耕作) which began serialization in 2019.
Kenshi Hirokane’s well-established Kosaku Shima series, however, is one of the few that can lay claim to that proud designation.
There aren’t a lot of manga series that have been in continuous publication since almost four decades ago.
Serialized in Weekly Morning magazine since 1983, the series, now in its eighth arc, follows the career and ongoing promotion of fictional salaryman Kosaku Shima.
