Contributors
The people who build JLPT Mastery — writers, native-speaker reviewers, teachers, engineers, and moderators. Every article is written by a named human and fact-checked before it ships, and the product itself is shaped by people who care about getting the details right.
Editorial Team
The in-house editorial team behind JLPT Mastery. We write and fact-check study guides, test-prep breakdowns, and career advice for learners working toward N5 through N1.
Founding Member & Lead Engineer
Founding member of JLPT Mastery who designed the platform's architecture and made the core product and engineering decisions behind it. He built the adaptive practice engine, the streak-based mastery state machine, and the Confusion Intelligence system that targets the exact word pairs each learner mixes up — spanning vocabulary, grammar, and full mock exams across all five JLPT levels (N5–N1). He also shapes the editorial direction and fact-checks the guides that go out under the JLPT Mastery name.
