The "More Students, More Paperwork" Problem

Late March. You're in the middle of spring intensive courses, and inquiries from new students starting in April are rolling in — for tutors, this is peak earning season.

But hold on a moment.

When your student count jumps from 5 to 8, what happens to your administrative workload?

The more students you take on, the heavier this burden grows — proportionally. During your busiest season, losing time to administrative tasks that don't directly generate revenue is completely counterproductive.

AI Automation Tools for ¥500/Month — The Future Is Here

2026 Trend
AI and automation tools for sole proprietors are rapidly becoming more affordable. Workflow automation that used to cost thousands or even tens of thousands of yen per month can now be started for as little as one coin (¥500/month). Independent tutors are exactly the kind of professionals who should be riding this wave.

Lately, the buzz around AI in education never stops. In an era where high school textbooks feature QR codes linking directly to digital learning materials, isn't it a bit unbalanced for the teaching side's back office to remain analog?

That said, you don't need an elaborate system. All a tutor really needs is a system that automates three things: recording, tallying, and invoicing.

With Kagemusha System, Automation Is Done in 3 Steps

Step 1: Add lessons to Google Calendar (just like you always do)

No special steps required. Simply add your lesson schedule to the Google Calendar you already use. Include the student's name in the title, and Kagemusha System automatically recognizes it.

Step 2: After the lesson ends, do nothing

Once a calendar event passes, Kagemusha System automatically transfers the lesson record to a spreadsheet. Rescheduled lessons and time changes are reflected simply by editing the calendar.

Step 3: Receive your PDF invoices automatically at month-end

When the month rolls over, the system automatically tallies session counts and amounts for each student and generates PDF invoices. All you have to do is send them.

Right Now — Before the New Term Starts — Is the Best Time

Once April hits and your student count grows, you won't even want to spare the time for setup. While you're still in spring intensive courses, take just 5 minutes to get everything configured.

The moment the new term begins, your lesson records will be organized automatically, and PDF invoices will be waiting for you at the end of each month.

Reasons to Start Now

Why not start this spring by creating an environment where you can focus entirely on teaching your students?
