生き甲斐 • Practice with Purpose.
ikigai.study is an interactive Japanese language learning dojo designed to bridge structured classroom pedagogy with tactile, distraction-free modern tools.
Bridging Classroom & Craft
Most language apps force learners to choose between rigid flashcard lists and gamified gimmicks detached from real curricula. ikigai.study was built to unite both worlds.
Every drill, grammar pattern, and vocabulary deck aligns directly with trusted classroom textbooks—including Genki I & II and Adventures in Japanese—alongside complete JLPT N5–N1 datasets and authentic Japanese KanjiVG stroke-order geometry.
Whether you are conjugating て-forms in the Training Ground, forging radicals in Kanji Alchemy, or reading graded stories in the Tadoku Lounge, every interaction is crafted to build genuine fluency.
Built by a Teacher, Free for Everyone
ikigai.study is created and maintained by a classroom Japanese teacher trying to build something cool, practical, and effective for his own students and the global Japanese learning community.
When students needed better ways to drill verb conjugations, untangle tricky particles, or practice counters without hitting paywalls or distracting banner ads, Sensei started building these tools after school.
Today, every module and printable worksheet on this site remains 100% free, ad-free, and distraction-free—with zero account walls or student tracking—so any classroom or self-learner in the world can jump right in and study.
Self-Hosted on a Local DGX Spark Server
Rather than relying on bloated ad-tech clouds that monetize user attention, ikigai.study runs on a self-hosted local DGX Spark server. We pair fast local caching and on-premise compute with targeted AI language models for interactive modules like Kanji Alchemy, Kaiwa Roleplay Dojo, and Shiritori.
Community supporters on Patreon, Buy Me a Coffee, and Web3 help cover recurring domain registration, server upkeep, electricity, and AI API costs—keeping every feature open and free for students everywhere.
