Sakamoto Days is one of the most anticipated anime adaptations recently, and fans were thrilled to learn more about its production at Anime Expo 2025. Director Masaki Watanabe shared in a recent interview the meticulous attention to detail involved in character design, revealing a particularly tough challenge that nearly compromised the anime’s visual integrity.
Simple Designs Prove to Be a Major Challenge in Sakamoto Days

While many action series rely on elaborate designs and flashy effects to impress viewers, Sakamoto Days takes a completely different approach. According to Watanabe, the characters feature deceptively simple designs. They lack flashy highlights or signature marks often seen in other animated characters, such as star-shaped scars or brightly dyed hair that make them easily recognizable.
This minimalism, which might seem easy at first glance, actually became a double-edged sword. Watanabe explained that even the smallest mistake could ruin everything. The animators had no “cheat codes” to hide errors.
The Battle to Keep Each Character’s Look Consistent in Sakamoto Days

The characters rely heavily on subtle features like face shape, eye size, and the precision of line work. Watanabe shared that the animators had to be almost obsessive about these fine details, especially the facial lines and stroke widths.
He emphasized that even the slightest change in a line could make a character look completely off from the original. This demand for absolute accuracy required constant revisions, causing significant delays and logistical pressure during production. It was more than a minor inconvenience, it posed a real threat to the visual consistency of the entire series.

Watanabe admitted that maintaining character integrity required frequent and meticulous corrections. A character’s identity could be lost if something as small as slightly larger eyes or a too-curved jawline slipped through. In animation, where every frame counts and continuity is key, this level of precision was a tough challenge.
Despite these obstacles, the production team’s determination to deliver a faithful and polished adaptation remains clear. Their relentless effort and attention to detail have helped Sakamoto Days preserve the clear, expressive visuals that are a standout feature of the manga.
In short, the seemingly simple design was one of the biggest hurdles in bringing Sakamoto Days to the screen. By overcoming this barrier, director Watanabe and his team have laid a solid foundation for one of the most faithful and refined anime adaptations of recent years, showcasing their talent and dedication.
