Validation prototype
Eight-week founding cohort
Structured N3 → N2 study support based on the prototype. This is a course experiment, not a promise of passing N2.
What the cohort includes
- A structured weekly study plan
- Guided grammar lessons based on the prototype
- Eight asynchronous weekly check-ins
- Course feedback and adjustment prompts
- Duration: eight weeks
- Configured kickoff: August 1, 2026
- The cohort runs only after eight verified deposits. If the minimum is not reached, every deposit is refunded in full.
- Total founding price: JPY 9,800
- Deposit now: JPY 3,000, credited toward the total
- Balance at kickoff: JPY 6,800
