"Ukeru" — What I Received from Master Tezuka

The word ukeru has no single kanji that captures its full meaning. The character 受ける means to receive or to hand over an object, but when we say a manga or anime uketa or ukenai, the word becomes an indicator of whether something has reached the hearts of the audience – those who watch, those who listen. One day, Master Tezuka invited me out. “Tsuki-san, I’m heading to Ginza today. Want to come along?” ...

Reality and Realism

Verisimilitude These two words are surprisingly often conflated. Not just by young students, but by professionals as well. I would like to think about that a little. Animation is, above all, a job that involves drawing a great many pictures. Twenty-four per second. In the days of film, early animation drew every single one of those frames. One drawing per frame — each one drawn individually. Then it was discovered that shooting each drawing for two frames did not greatly alter the movement. ...

On Images and AI

The Lines Humans Draw The lines in a drawing made by human hands carry momentum, languor, suppleness, hesitation, sensuality. Some of these qualities are consciously sought; others emerge unconsciously. In a picture drawn by a person, such qualities are naturally adjusted and woven in. The word “sensuality” does not mean only sex appeal. We often speak of “mature allure,” but this is a complex thing, and eroticism is no simple matter either — because sex appeal has no pattern. ...

The Bank System

What Is the Bank System? Long ago, Osamu Tezuka — creator of Astro Boy, the pioneering television anime — devised a method called the Bank System to produce 30-minute episodes every week. “Bank” means to store. Unlike today, animation at that time was drawn on paper, traced onto cels, and painted by hand. Normally, cels were discarded after a production was completed. But Tezuka decided to keep and organize certain cels rather than throwing them away — bust shots, waist shots, close-ups, walking shots, flying shots, crying, laughing, lip-sync shots, and other footage likely to be reused. This was the Bank System. ...

How Far Can AI Take Our Jobs?

There is a work called The Congress (2013, directed by Ari Folman) that blends live-action film with animation. It is based on a novel by Stanisław Lem (born in Ukraine, raised in Poland), the author famous for Solaris. A producer approaches an actress whose prime is passing and asks her to sell her current likeness — her image rights. Struggling with a difficult illness and crushing medical bills, she agonizes but ultimately accepts the offer. She is then recorded from head to toe by a full-body 3D scanner — and so the story continues. ...
