From today (April 21) through tomorrow, yellow dust is expected to blanket a wide swath of Japan, from the north to the west. Laundry has to hang indoors, windshields feel gritty, and even the landscape outside looks hazy.
Today, let's talk about how to "clear the view" on both your scheduling and parent communication as a private tutor.
The Classic Private Tutor Problem: "Yellow-Dust-ification" of Your Schedule
If you work for a cram school or company, there's a system in place for you. But private contracts? You handle everything yourself. You might start out managing just 2 or 3 students fine — then before you know it, this happens:
If you write the same appointment in three places, something's guaranteed to slip. Just like yellow dust — the scary part is you don't even notice it piling up.
"Scheduling" and "Parent Communication" Are One and the Same Problem
Fixing just the scheduling isn't enough. Why? Because lesson plans always move in tandem with parent communication.
- Reply "Sure, we can change the time" → Update calendar → Reflect in tuition calculations
- Lesson ends → Send "Here's what we covered today" report → Create invoice at month-end
The era of humans doing this whole chain by hand should really be over by now.
| Task | Manual Style | Automated Style |
|---|---|---|
| Managing lesson schedule | Paper planner, LINE, phone memos (scattered) | Google Calendar, one place |
| Reflecting schedule changes | Manually update 3 places, miss one | Just update the calendar |
| Calculating tuition | Hand-calculated at month-end | Auto-aggregated from lesson records |
| Reports to parents | Typed manually after every lesson | Generated from template + records |
| Creating invoices | Hand-made in Word or handwritten, one by one | Auto-generated as PDFs |
What Changes with Kagemusha System?
Kagemusha System is a tool built for private-contract tutors that fully automates attendance tracking, tuition calculation, and invoice creation (500 yen/month).
The mechanism is simple.
STEP 1. Add lessons to Google Calendar
Just like you always do. Only input required: the schedule itself.
STEP 2. After each lesson, records auto-accumulate in a spreadsheet
Who you taught and for how long — it all piles up without you lifting a finger.
STEP 3. At month-end, PDF invoices generate themselves
One per student. No hand calculations. That dreaded end-of-month task drops to "0 minutes."
All data stays inside your own Google account. Nothing gets sent to external servers. This is quietly a big deal (you don't want to use a tool that ships your students' and parents' personal info off somewhere, right?).
Before & After
Your weekend at month-end disappears. Flipping between paper planner, Excel, and LINE history, punching a calculator, stuffing envelopes. Worse visibility than yellow dust.
Your weekend at month-end comes back. Just send the invoice PDFs already sitting in your Drive. Clear view.

Wrap-Up: You Don't Have to Wait for the Wind to Change to Clear the View
Yellow dust passes in a few days. But manual admin work doesn't just fade away on its own. The more students you get, the thicker it builds up.
2. Don't calculate tuition by hand (let it be auto-generated from lesson records)
3. Stop "creating" invoices at month-end (set it up so they're already done)
500 yen a month. 5-minute setup. By the time the spring skies clear, your month-end should be clear too.
