Game Freak Water Research Could Suit Pokémon Winds and Waves' Ocean Setting

A newly published piece of graphics research co-authored by a Game Freak programmer has prompted understandable curiosity about Pokémon Winds and Waves, the next mainline Pokémon RPG scheduled for 2027 on Switch 2. The study concerns a challenge with obvious relevance to an adventure built around seas, shorelines, and an apparent underwater region: how to render moving water and other liquids with convincing detail without demanding an impractical amount of processing power.

Game Freak programmer Fumiya Narita worked on the paper with University of Tokyo professor Takashi Kanai. Their research was presented at the Pacific Graphics 2026 conference in Singapore. While the work does not include a demonstration from a Pokémon game, and Game Freak has not said that its methods are being used in Pokémon Winds and Waves, the thematic overlap is difficult to ignore.

The game's debut trailer featured wide ocean views with substantial visible motion across the water. It also showed an underwater biome, creating the possibility that players may be able to travel below the surface. Those settings could place water at the center of the game's visual identity rather than treating it as distant scenery. If the research ever informed production work, it could potentially help Game Freak make those environments more lively while working within the practical limits of a console game.

Why water is a demanding problem in games

Water often looks simple at a glance, but it is among the more difficult natural materials to portray convincingly in real time. A still lake, a shallow shore, a moving river, rainfall, foam, a boat wake, a creature breaking the surface, and an underwater current all require different visual cues. Players may not consciously inspect every calculation behind them, yet they quickly notice when motion feels repetitive, disconnected, or unnatural.

Detailed liquid simulation can be computationally expensive because it involves an enormous number of possible interactions. Water flows, collides, separates into droplets, reconnects, ripples outward, and reflects light in ways that change from moment to moment. Trying to calculate every part of that process at the highest level of precision is generally too costly for an interactive game, where the system must also handle characters, environments, effects, animation, user input, and gameplay logic.

The research by Narita and Kanai addresses that balance between performance and visual richness. Its general aim is to make liquid rendering more efficient without losing the details that make water feel expressive. Rather than devoting equal effort to every aspect of a simulation, the approach is intended to simplify work happening behind the scenes while emphasizing the visible moments that matter most to the viewer.

That could include elements such as splashes, ripples, and waves: the brief details that communicate force, scale, and interaction. In a game, those are often the moments players remember. A Pokémon leaping from the sea, a trainer wading into the shallows, or a large wave rolling toward a coast can be more convincing when the water visibly reacts, even if the underlying system is carefully optimized rather than physically simulating every drop at full complexity.

A natural fit for Winds and Waves' first footage

Pokémon Winds and Waves appears, from its initial trailer, to be embracing a distinctly summery marine atmosphere. The footage presented expansive oceans and active water rather than a quiet, static backdrop. That presentation invites expectations that travel across or around the sea could be a major part of the experience.

The underwater biome shown in the trailer is equally significant. Underwater scenes pose their own rendering considerations. The game needs to sell depth, movement, visibility, and the sensation of being surrounded by water, while still ensuring that the environment remains readable for players. Surface effects may need to be visible from below, and the transition between coasts, open water, and submerged locations can be particularly important if diving is part of the final game.

None of this proves that Winds and Waves uses the technique described in the Pacific Graphics paper. Research papers can be exploratory, may be developed separately from a specific commercial project, or may influence future tools and workflows without appearing in one identifiable feature. The paper did not showcase an in-game Pokémon implementation. It is also possible that any connection, if one exists at all, would be limited to certain visual effects rather than a sweeping simulation system.

Still, the research illustrates an area of technical interest that maps unusually well onto the game's announced setting. A title focused on winds and waves has clear reason to benefit from better-looking and more efficient water. The possibility is intriguing precisely because the trailer appears to place water in so many roles: as scenery, a navigable boundary, a source of motion, and perhaps an explorable environment in its own right.

Efficiency matters as much as spectacle

For players, the most desirable outcome is not necessarily a claim of maximum realism. Pokémon games need visual effects that support play. Water should make coastlines and islands feel appealing, help communicate where characters can move, and reinforce the behavior of creatures and the world around them. It also needs to do this reliably during exploration, encounters, and any moments where many effects are on screen at once.

Efficiency is therefore more than a technical footnote. If a liquid system can direct resources toward the most noticeable features, developers may have greater flexibility to maintain detail where it has the strongest impact. Instead of spending performance on invisible or less meaningful calculations, a game could prioritize a splash at the point of contact, the wake behind movement, or waves that give a large stretch of water a sense of scale.

This kind of prioritization is especially relevant for a game targeting a single platform. Pokémon Winds and Waves is currently expected to arrive exclusively on Switch 2 sometime in 2027. Console development often involves finding the best possible visual result within known hardware constraints. Better methods for managing demanding effects can be as valuable as raw hardware power, because they give artists and designers additional ways to make a world feel active.

That does not mean players should treat a research presentation as a promise of a particular visual standard. There has been no confirmation of dynamic ocean mechanics, dive functionality, reactive waves during gameplay, or any other specific feature tied to the paper. The trailer establishes a water-heavy aesthetic, but it does not yet define exactly how exploration, environmental interaction, or underwater areas will function.

Another open question for the next mainline RPG

Water technology is not the only major unknown surrounding Pokémon Winds and Waves. The game has also drawn questions about its battle design. A Game Freak veteran has suggested that the combat system could change, raising the prospect that the series may not follow its familiar turn-based structure in the same way. At present, that remains an area where more concrete detail is needed.

Together, the unanswered questions suggest a project that may be aiming to establish its own identity rather than simply using an ocean theme as decoration. The setting shown so far could support a different rhythm of exploration, while possible changes to battles could alter how players engage with Pokémon across that world. But the publicly available evidence remains limited, and the final shape of the game should not be assumed before Game Freak shares more.

For now, Narita and Kanai's work is best viewed as promising technical context rather than confirmation. It demonstrates that a Game Freak developer is involved in research focused on making detailed liquids more manageable to render. It also arrives at a moment when the studio has revealed a Pokémon adventure whose first imagery prominently features rolling seas and underwater spaces.

Whether that overlap becomes visible in the finished game will not be known until closer to Pokémon Winds and Waves' 2027 launch window. Until then, the paper offers an interesting glimpse at the kind of graphics challenges that can sit beneath a seemingly simple image: sunlight on water, a ripple spreading from a character's steps, or a wave moving across a far-off horizon.
