How it fits together
My Senpai is a set of focused tools, not one giant course.
The products can be used independently. If you use several, the learning tasks complement each other: recognize, produce, read and recall.
Recognize
Build a reliable base before asking yourself to use the language quickly.
- Kana Challenge builds kana recognition and recall.
- Crossword turns vocabulary knowledge into active recall.
Produce
Move from understanding a language to actually producing it.
- FluencyTool gives you repeated speaking practice.
- Native audio provides a model for shadowing and comparison.
Read
Use real Japanese without removing every support that makes it possible.
- YoMoo adds furigana and dictionary support to authentic text.
- The Japanese Learner's Map helps identify what to work on next.
Recall
Review what matters instead of treating every word or sentence as equally important.
- Spaced review reinforces previously studied material.
- Practice can be tied to the language you are already reading and speaking.
Japanese
Japanese learning from kana to JLPT N1.
My Senpai covers several distinct stages of Japanese study rather than treating "learning Japanese" as one activity.
Start with kana
Use Kana Challenge when hiragana or katakana is the immediate obstacle. The program is designed around a 30-day progression rather than an open-ended character list.
Build vocabulary recall
Use Crossword to practice producing Japanese vocabulary from English clues across JLPT N5-N1.
Read real Japanese
Use YoMoo when textbook Japanese is no longer enough. Furigana, dictionary lookup and article vocabulary support help you stay with authentic text.
Practice speaking
Use FluencyTool for production practice, native audio and pronunciation feedback. The goal is to make speaking part of regular study, not an occasional test.
JLPT is the Japanese-Language Proficiency Test, with five levels from N5 to N1. See the official JLPT levels for the test's published level descriptions.
English
English speaking practice from CEFR A1 to B2.
FluencyTool also provides a structured speaking track for English learners who need more production practice.
Practice production
Record yourself, work from native audio and review recurring speech problems. The focus is on producing language rather than only selecting an answer.

The English track covers CEFR A1 through B2. The Common European Framework of Reference uses can-do descriptions to describe language ability across levels.

Built around the gap between studying a language and using it.
My Senpai is built in Tokyo around a simple idea: different learning problems need different practice. Instead of putting every activity into one course, the platform combines focused tools for recognition, production, reading and recall.
The Japanese side covers kana through advanced JLPT study. FluencyTool extends the same production-focused approach to English speaking practice.
My Senpai means "senpai" as a guide who is a few steps ahead and helps you move forward.
