One Piece has long been a cornerstone of anime, captivating millions with its epic storytelling and stunning animation. As the series continues to evolve, so does the complexity behind its production. In a recent interview at Japan Expo, One Piece’s chief animation director, Keiichi Ichikawa, opened up about some of the challenges faced during the Wano arc. Specifically, he revealed how hiring foreign animators and time constraints led to a series of problems that impacted the arc’s animation.
This revelation sheds light on the growing pains of an anime that’s reached global heights, and it highlights the ever-evolving nature of the anime industry. Let’s take a deeper dive into these issues and how they might affect the future of One Piece.
Key Features of the ‘One Piece’ Animation System
The One Piece anime is one of the longest-running and most beloved anime series worldwide. Its success can be attributed not just to Eiichiro Oda’s rich storytelling, but also to the talented animators at Toei Animation. The series’ animation is known for its detailed action scenes and vibrant colors, which are made possible by a highly skilled production team.
However, with growing global demand and the series expanding into new markets, new challenges are emerging. Here’s a breakdown of the current animation system and issues discussed by Ichikawa.

Challenges Faced by One Piece Animation: Foreign Animator Concerns
In his interview, Ichikawa discussed a crucial issue: the difficulties arising from the integration of foreign animators into the team. While outsourcing animation work to international talent has become common in the anime industry, it comes with unique challenges that need to be addressed for smooth production.
The Problem of Second Key Animation:
Second key animation, or “in-betweening,” is a critical part of the animation process that ensures fluid movement between keyframes. Ichikawa revealed that many of the foreign animators brought in to assist with One Piece struggled with this aspect, leading to inconsistencies in the animation quality. This issue became particularly noticeable during the Wano arc, which is known for its high-intensity action sequences.
Time and Budget Constraints:
Ichikawa also highlighted how time and budget constraints affected the quality of the animation. With an ever-increasing workload due to the success of the series, Toei Animation’s resources have been stretched thin. This limited budget and the intense production deadlines only exacerbated the issues with the integration of foreign animators.
Solutions and Future Plans
As Toei Animation embarks on a ten-year expansion plan, which includes the hiring of hundreds of new staff members across Asia, these challenges may become more prevalent. Ichikawa acknowledged that there is currently no efficient system in place to train foreign animators in the nuances of second key animation. This gap needs to be addressed if the quality of One Piece’s animation is to be maintained in future arcs.
While there is no immediate solution to this issue, Ichikawa suggested that better communication, more targeted training, and a refined onboarding process for foreign animators could be key to resolving these problems.
Benefits of Maintaining High-Quality Animation for One Piece
Despite these challenges, maintaining high-quality animation is vital for the continued success of One Piece. Fans around the world have come to expect top-tier visuals alongside the compelling storytelling that has defined the series for over two decades.
- Consistency in Quality: One of the reasons fans have remained loyal to One Piece is the consistency of its animation quality, especially during critical arcs such as Wano.
- Increased Global Appeal: High-quality animation attracts viewers not just in Japan but also internationally. The global popularity of One Piece owes much to the appeal of its visual storytelling.
- Future Growth: By improving its animation systems and addressing the current issues, One Piece can continue to evolve while maintaining the standards that have made it a global sensation.

Why the Wano Arc’s Animation Issues Matter?
The Wano arc is one of the most significant and anticipated arcs in One Piece, both for its story and its animation. Its intricate art and high-stakes action sequences are essential to the arc’s impact. Any flaws in animation quality detract from the viewer’s experience and can impact the overall reception of the arc.
Ichikawa’s remarks emphasize the importance of managing resources effectively, especially as Toei Animation moves toward a global expansion. With a growing number of animators joining the fold, addressing the challenges that arise from outsourcing work to foreign talent is essential to maintain the quality that fans expect.
Recent Updates: What’s Next for One Piece Animation?
As Toei Animation prepares for its global expansion, the studio is expected to recruit more animators, which could potentially improve animation quality in the future. However, Ichikawa’s concerns about foreign animators need to be addressed to ensure the studio can continue to produce world-class animation. Additionally, the success of the live-action adaptation on Netflix could provide additional resources for the anime series in terms of production budgets and talent.
Upcoming Releases:
- Season 2 of Netflix’s One Piece: Set to premiere on March 10, 2026, this season will continue the live-action story with new casting announcements and more content.
- Future Arcs in the Anime: The upcoming arcs in the anime are expected to be as action-packed and visually impressive as Wano, so resolving the current animation issues is crucial.
