Joint Custody Starts in April. The Age of Sharing Is Here
On April 1, 2026, the revised Civil Code took effect, launching the joint custody system that allows both parents to retain parental authority even after divorce.
An era where childcare responsibilities can be shared. That's wonderful.
…But it got me thinking.
Who are you sharing your "admin work" with?
As a privately contracted tutor, you're not just teaching lessons—you're creating invoices, calculating tuition, managing schedules, contacting parents—all by yourself.
In other words, you have "sole custody" of your admin work.
In the age of joint custody, isn't going solo on admin getting a bit much?
The Reality of "Solo Admin" for Privately Contracted Tutors
A privately contracted tutor is a teaching professional who simultaneously serves as their own accountant, secretary, and sales rep—a one-person business wearing three hats.
But honestly, you'd rather focus on teaching. Every minute spent on admin is a minute you're thinking, "I wish I could hand this off to someone."
It's not quite joint custody, but isn't it time to consider "divorcing" your admin work?
Manual vs. Automated: How Much of a Difference Does It Make?
| Task | Manual (Solo) | Kagemusha System (Automated) |
|---|---|---|
| Lesson Records | Calendar → Excel transcription (15 min/day) | Auto-imported from Google Calendar (0 min) |
| Tuition Calculation | Tallied per student in Excel (1 hour/month) | Auto-calculated in spreadsheet (0 min) |
| Invoice Creation | Created one by one in Word (30 min/month) | Auto-generated as PDF (0 min) |
| Parent Communication | Sent individually via LINE (20 min/month) | Reports sent automatically (0 min) |
| Data Storage | Excel files on your PC (risk of loss) | Contained within your Google account (secure) |
Month-end solo admin alone eats up over 2 hours total. Over a year, that's more than 24 hours—a full day's worth of teaching time "stolen" by admin work.

In other words, you can hire the "other parent" for your admin work for just ¥500/month.
And this "partner" never complains, never makes mistakes, and works 24/7. Might even be better than a human partner (sorry about that).
① Add Lessons to Google Calendar
Just manage your schedule as you normally would. Zero additional input required.
② Kagemusha Tallies Automatically
Lesson count, hours, and amounts are automatically reflected in your spreadsheet. Tuition calculations happen on their own.
③ PDF Invoices Are Auto-Generated
At month-end, PDF invoices for each student are automatically created. All you have to do is send them.
"Precisely Because You're Independent" You Need a Management Tool
At a large tutoring agency, headquarters handles the admin. But with a private contract, it's different. It's all on you.
On a Sunday at month-end, you open Excel after your last lesson to create invoices. At 11 PM, you send them to parents via LINE. Then you get a reply: "The amount is different from last month…" Cold sweat.
Month-end? I don't do anything. Lessons entered in my calendar are automatically tallied, and PDF invoices are already done. Sunday nights, I'm watching Netflix.
