905 hPa. Intense. But There's a Storm That Comes Every Month
Typhoon No. 4, "Shinrakou," is approaching Japan at tremendous intensity—905 hPa with maximum gusts of 85 m/s. A typhoon this powerful in April hasn't been seen in 11 years. Truly unprecedented.
But here's the thing: for independent private tutors, a "powerful storm" rolls in every single month.
When the end of the month arrives—
- "Wait, what time was last Tuesday's lesson again?"
- "When did I reschedule that makeup lesson for Tanaka-kun?"
- "Did I ever notify the parents about that schedule change…?"
You scroll back through your calendar, dig through LINE chat histories, cross-reference with your notebook—
How is this any different from a typhoon making landfall every month?
- Schedule management gets more "intense" with every new student
- Notes get scattered with every reschedule or time change
- You feel anxious at month-end wondering, "Did I actually teach that lesson?"
- You've had close calls with double-booking
You Can Shelter from a Typhoon. But You Can't Escape Paperwork
With a typhoon, you check the forecast and prepare. Worst case, you wait for it to pass.
But month-end paperwork? Skip it, and it comes back twice as hard next month. Overdue invoices, unrecorded lessons, parents you forgot to contact…
With 5 students, you can barely manage. What about 10 or more? That's a Category 5 direct hit.

Do You Understand What "Just Add It to Google Calendar" Really Means?
"I already use Google Calendar," you might be thinking.
What makes the Kagemusha System different is that your calendar entries automatically become attendance records.
1. Add Lessons to Google Calendar
Just create events the way you normally do. No special formatting required.
2. The Kagemusha System Reads Them Automatically
Calendar data is automatically transferred to Google Sheets—organized by student and date.
3. PDF Invoices Are Ready at Month-End
Invoices are auto-generated as PDFs from the tallied data. Print them or email them—your choice.
In other words, schedule management = attendance tracking = invoice creation—all connected in one seamless flow.
Even if you reschedule a lesson, just update the calendar and the totals and invoices adjust automatically. That nagging worry of "Did I update everything?" becomes a thing of the past—permanently.

FAQ
Preparedness Matters for Typhoons—and for Schedule Management
Typhoon No. 4 has been making headlines as an unprecedentedly powerful storm for April.
But think about it. Typhoons come a few times a year. The month-end paperwork storm hits every single month without fail.
And while a typhoon passes and it's over, paperwork you skip piles up as debt for the following month.
Before the next powerful typhoon hits, why not clear out your monthly "paperwork storm" first?
For just ¥500/month, automate everything from schedule management to invoice creation. It all stays within your Google account, so there's zero risk of data leaks.
You can't stop a typhoon—but you can stop the paperwork storm today.
