Today, Sunday May 3rd, the "Fukagawa Obake Festival 2026" is being held at the Fukagawa Shiryokan-dori Shopping Street in Tokyo. It's a sacred gathering for yokai fans, with around 70 vendors selling yokai goods, ghost story books, and spooky street food.

…So why are we talking about a ghost festival on a tutoring blog?

Because there are yokai living in YOUR month-end too, aren't there?

Do any of these symptoms sound familiar?

Yep. That's the work of yokai.

Meet the 3 Yokai That Show Up at Month-End

If you run a private tutoring business, there are yokai that appear like clockwork every month. Let's visualize them.

👻
The Invoice Ghost: "Heh heh heh… you'll never remember how many lessons you taught this month…"
🧮
The Tuition Calculation Yokai: "Hourly rate × hours × sessions… the calculator doth not agree, doth not agree…"
📝
The Report Kappa: "You haven't messaged the parents on LINE yet, have you? My head dish is drying out…"
Enough! I'll send all of you to the afterlife with the Kagemusha System!

Jokes aside, this is something every private tutor experiences. With 3–5 students, you can power through with willpower. But the more students you have, the stronger the yokai become.

How to Banish These Yokai (Seriously, in 5 Minutes)

The Kagemusha System is a tool that exorcises all three of these month-end yokai in one strike. 500 yen per month.

Add lessons to Google Calendar

Use the calendar you already have. Just write the event as "[Student Name] Math." That alone becomes your attendance record.

The spreadsheet tallies it automatically

Lesson hours, per-student totals, automatic tuition calculations. No more pounding the calculator. The Tuition Calculation Yokai—dispelled.

PDF invoices generated with one button

Invoices with student names, subjects, session counts, and amounts—generated instantly. The Invoice Ghost—sent to the afterlife.

Lesson records double as report material

Jot "Today: quadratic functions" in the calendar's notes field, and you've got material for parent updates. The Report Kappa's head dish—refilled with water.

Before & After: The View at Month-End

Before (haunted month-end)

Saturday night, beer in one hand, glaring at your planner. "Hmm, how much was this kid last month?" Scrolling back through LINE history. The calculator won't add up. 2 AM, invoices finally done. Sunday, you sleep the day away.

After (yokai-free month-end)

Just use your calendar like normal. At month-end, click one button and PDF invoices roll out. Time required: zero minutes. Your weekend is yours again, and you can actually go to that ghost festival you wanted to check out.

Cheaper than a real shrine exorcism. And the effect lasts forever (until you cancel).

All your data stays inside your Google account

The Kagemusha System never sends your student information or tuition data to external servers. Everything stays within your own Google Calendar, Spreadsheet, and Drive. We banish yokai, but we don't steal data. We're a conscientious exorcist.

Frequently Asked Questions

Can I really set it up in 5 minutes?
Yes. Sign in with your Google account, copy the template, enter student names and hourly rates—done. You'll finish before getting back from buying takoyaki at the ghost festival.
Can I cancel anytime?
Cancel whenever you want. It's a monthly subscription, so you can stop next month. Once the yokai are completely banished though… well, you probably won't want to bring them back.
Can I use it if I can't see yokai?
Absolutely. In fact, the people who don't notice them are the ones losing 3–5 hours a month without realizing it. Time for an exorcism, right now.
