48×61 is an obscure one-shot anime short built around a very specific creative joke: director Rintaro and manga/anime creator Katsuhiro Otomo are represented in a bicycle race. The title points to their ages around the project — Rintaro at sixty-one and Otomo at forty-eight — and the short was produced by Madhouse.

48×61 is a short movie made by the famous director Rintaro (Astro Boy, Metropolis, …) for the Japanese manga artist and director Katsuhiro Otomo (Akira, Mushishi, …). It was produced by Studio Madhouse. This movie was made when Rintaro was 61 years old and Katsuhiro 48 years old.

Source Boundary

AniList and Kitsu agree on the core premise, one-episode format, creators-as-cyclists idea, Madhouse production note, and general comedy/sports framing. No active anime-specific Fandom community or stable public scene-by-scene transcript was found, so PopRot covers the short from verified metadata and does not invent shot order, dialogue, or unavailable screenshots.
