Toru Iwatani never thought his video game character modeled after a pizza with a missing slice would spread worldwide and still be so loved after three decades.

But it did, as demonstrated by an exhibition celebrating the 30th anniversary of Pac-Man at 3331 Arts Chiyoda in Chiyoda Ward, Tokyo. Featuring the original game and all the spinoffs, as well as related goods and live events, the celebration kicked off Saturday and continues until next Monday.

"When I walked into the exhibition and saw the variety of game machines, I thought a miracle had happened," Iwatani said during a preopening event Friday. Indeed, the displays filling the venue are quite imposing.
