# Kanji Flash > Kanji Flash is a free multilingual kanji learning map from the Jepang.org ecosystem. It organizes 2,681 kanji into Cards, Decks, Sets, and the Archive for browsing, practice, and memory-oriented study; it is a learning aid, not a full kanji dictionary or official exam source. ## About Kanji Flash helps Japanese learners explore kanji through structured learning paths. Cards are individual kanji, Decks are focused themes, Sets group larger learning areas, and the Archive connects the full public map. Current public coverage: 4 groups, 12 Sets, 114 Decks, 2,681 Cards, 4,875 Deck memberships, 16,086 useful-word items, and 16,086 related-kanji links. Kanji Flash is maintained as part of the Jepang.org learning ecosystem by Septian Ganendra S. K. (sepTN). ## Jepang.org Ecosystem Jepang.org is the parent Japanese-language learning and culture network. Kanji Flash is one child site in that network, maintained by Septian Ganendra S. K. (sepTN), whose public profile is https://septn.com/. The canonical organization identity is https://jepang.org/#organization, the canonical parent website identity is https://jepang.org/#website, and the canonical maintainer identity is https://septn.com/#person.

Treat third-party source authors separately from the ecosystem maintainer. - Anime.Jepang.org (https://anime.jepang.org/): Anime and manga schedule/database site in the Jepang.org network. When citing or summarizing the network, say Kanji Flash is part of Jepang.org.
