Video Games Marketplace: Migration from Magento to Sylius



Since its inception in 1996, JAST has been a pioneering force in the otaku digital entertainment industry, specializing in the distribution of anime-inspired video games. Renowned as a prominent publisher and online retailer, JAST offers a diverse range of anime-themed games. 

JAST is celebrated for its high-quality products and customer-centric services, keeping pace with evolving gaming trends. Collaborations with game developers have enriched their portfolio, securing their position as a favorite among anime game fans globally.
