Kenichi Shikishima

Also known as 敷島 ケン一 (Shikishima Kenichi)

Hello, My Name (in English) is…

As if to describe his status as Tezuka’s top-billed star, Kenichi’s name is made up of the Hiragana characters for Ken (ケン) and Ichi (一), or “one.” So, he literally is “Ken Number 1!”

Distinguishing Features

A prototypical hero who draws a lot of his look from early American animation, you can usually spot by the quiet look of determination in his large black eyes, as well as his “spit-curl and-polish” hair style.

Status: Major Star (★★★★)

Kenichi is the earliest and one of Tezuka’s most frequently cast boy heroes.  In fact, he more or less set the standard by which all the others are measured and is often seen as the antithesis of the “morally complex” Rock Holmes.  The eternal optimist, he possesses an unshakable faith in the inherent goodness in the world and human nature.  As the chief protagonist figure in many of Tezuka’s manga works, Kenichi’s plucky “never say die” attitude has seen him through a multitude of Earth-shattering crisis.  When not in a starring role as the boy hero, Kenichi’s nobility, loyalty and friendship usually serve him well as a classmate (usually class president) and/or a friend.

Notable Roles

Although he made his debut as “Pete” in Osamu Tezuka’s first professional long-form story manga New Treasure Island (1947), it is from his appearance as “Kenichi” in Dr. Mars (1947) that he gets his name.  However his full name, “Kenichi Shikishima” comes from his role as the scientist in Lost World (1948).  While he had a multitude of starring roles early on, including a memorable one in Jungle Emperor (1950-54), in all of them he basically embodies the kind of conscientiousness and purity of “childhood days”.

However, as the days of the Akahon (赤本) or “Red Book” manga – a term derived from the cheap and childish manga that was produced in early post-war Japan, which were usually printed on cheap paper that had a reddish brown colour – came to an end, Tezuka realized he needed to make a change. The “eternal boy scout” motif can only take a story so far, and Tezuka realized that his manga needed to focus on “realities that cannot be communicated through the agency of simple integrity”. Since his characters needed to exist as outsiders from human society to be most effective in delivering on his themes, his story leads (even Astro Boy) came to develop other facets to their personalities than simple, innocent righteousness.  But, since this was such a core component of his personality, as Tezuka himself explains, “I was forced to relinquish Kenichi from his role as protagonist because he lacked individuality.”

This realization marked a huge turning point in Kenichi’s career.  Although Tezuka’s personal fondness for the character led him to create Chief Detective Kenchi (1954-57) specifically as a vehicle to give Kenichi another starring role – this time with a bit of a harder edge – it was more or less his last.  Yet, instead of putting Kenichi through the moral transformation that Rock Holmes was forced to endure, Tezuka chose to let Kenichi maintain his purity and innocence of youth, and continued to cast him in straight supporting roles as “the righteous boy”.

Despite this, Kenichi did have a chance to expand his repertoire cast as the murderer in the Black Jack (1973-83) chapter “Twice Dead” (1974) and as the paralyzed boy in “The Legs of an Ant” (1974).
