Neptune Shares H5 Porting Know-How at Tokyo Game Show

Neptune announced on September 18 that it shared its H5 game porting know-how at Tokyo Game Show 2026 and unveiled three mini-games through the LINE booth.

Neptune participated in the partners' presentation session at the LINE GAME NEXT 2026 conference held for two days starting on September 17. At the event, alongside Director Atsushi Yoshimeki of MEC Labo and Director Kazuya Kunifu of Polygon Magic, Neptune introduced game development technologies, production know-how, and business experience.

Ahn Hyun-seok, Director of the H5 Game Business Office at Neptune, delivered a presentation under the topic of "Native Game H5 Porting Know-How," introducing methods to transition existing games into lightweight H5 formats while maintaining service stability and user experience.

Ahn highlighted "lightweighting" as the key challenge in H5 game conversion. He presented a method that separates the core game body from its resources, loading only the minimum resources required for initial execution while dynamically fetching the rest via a Content Delivery Network (CDN) when needed.

According to Neptune, Infinite Stairs, which applied this method, reduced its file size from 270MB to 33MB and shortened its loading time from over 30 seconds to under 10 seconds.

Neptune is supplying over 50 native games converted into H5 format across about 10 global platforms, including LINE. At this event, the company showcased and demoed Cat Snack Bar, Drill Drill Drill, and Infinite Stairs through the LINE booth.

Kwon Seung-hyun, Head of Neptune's Game Business Division, said, "We aim to secure global platforms that want to feature H5 games as in-app mini-games to increase user dwell time and offer diverse experiences as new clients, building this into a new revenue pipeline."
