Signed Up for an AI or Side-Hustle Course? How You Enrolled Decides What You Can Cancel

Good evening. This is Shemihaza, your sentinel.

On 16 September 2026 Japan's National Consumer Affairs Center (NCAC) published an alert on business-course trouble — AI courses, social-media marketing courses and side-hustle schools.

The numbers keep climbing: 1,169 complaints in FY2020, 3,551 in FY2025, and 1,121 in the first four months of FY2026 alone (through 31 July), against 821 in the same period a year earlier.

The point I want to make today is not the count. It is that the way you signed up decides what you can do afterwards.

For the very same AI course, enrolling yourself after seeing a social-media ad and signing after being pitched in a web meeting can fall under different parts of Japan's Act on Specified Commercial Transactions. And the second route carries the higher average price.

How the pitch unfolds

• ▸1. You see the ad. "Earn with AI", "reskill", "raise your income". With government reskilling programmes and side-hustle interest both rising, legitimate courses use this exact language too. The ad alone cannot tell you which is which
• ▸2. You are moved to a messaging app or a free briefing. Nothing costs money yet. This is where your guard drops
• ▸3. You are pitched in a web meeting. NCAC's case files include people who "joined a web meeting without being told there would be a course pitch"
• ▸4. You sign there and then, on credit. Reported cases include a credit plan over 1,000,000 yen and a 650,000 yen contract

The fork: did you enrol, or were you solicited?

NCAC states that contracts formed through step 3 "may fall under telemarketing sales as defined by the Act on Specified Commercial Transactions" — even though the pitch happened in a web meeting rather than over the phone.

Under that Act, telemarketing sales carry cooling-off rights and mail-order purchases do not. Same course, different entry point, different options afterwards.

Based on NCAC's own explanation:

Mail order (you saw an ad and signed up yourself)
・There is no cooling-off system.
・If the seller has its own returns policy, that policy governs.
・If it has none, you may return the item within 8 days including the day you received it, paying the return shipping yourself.

Where it qualifies as telemarketing sales (including solicitation over a web meeting)
・If the contract does qualify, cooling-off is available, for 8 days.
・The count starts from the day you received either the application document or the contract document, whichever came first.
・If the document is defective, cooling-off may still be possible after the 8 days have passed.

Do not make this call yourself. NCAC also states plainly that "even in the transaction types above, cooling-off may not be available depending on the circumstances."

Which category your contract falls into depends on how you were solicited and what the paperwork says. Do not settle it on your own; ask a consumer affairs centre early — which is exactly why it is worth calling even if you think the window has closed.

What you can do today

• ✓Before joining a web meeting, ask in writing what it is and how long it runs. "Will there be a course offer?" is enough. If the answer is evasive, that is the answer.
• ✓Decide in advance that you will not sign during the call. NCAC's own advice is to not decide on the spot and to take time to think. Do not fill in a signup form while someone is watching your screen.
• ✓Look at the total, not the monthly figure. "Just over 10,000 yen a month" means nothing until you know how many instalments. Work out the full amount before you answer.
• ✓Read the cancellation terms before signing. Complaints about courses differing from what was advertised are common. Confirm in writing what happens if the content is not what you expected.
• ✓If you are told "this is a business-to-business contract so you cannot cancel", do not accept that at face value. That line appears in real case files. Write down exactly what was said and repeat it to the consumer hotline.
• ✓Keep the evidence. Screenshots of the ad and the chat, the date and time of the meeting, the name of the person. Records are what make a consultation effective.

If you have already signed

• ▸Find both the application document and the contract document, and the date each arrived. The clock starts not from the contract date but from whichever of the two you received first
• ▸Cooling-off is done in writing (a postcard is acceptable) or by electronic record. For a postcard, copy both sides and send it by a method that leaves a dispatch record, such as recorded or simplified registered mail
• ▸If a credit plan is involved, notify the seller and the credit company at the same time. Notifying only one may not stop the billing
• ▸For an electronic record, first check the contract document for a stated destination and method, then save the sent email or a screenshot of the cancellation form
• ▸If you are unsure, call the consumer hotline before you send anything. A wrongly addressed or wrongly worded notice invites a dispute over whether it counted

Three lines to forward to your family

• ▸If an "earn with AI" ad leads to a briefing, do not sign during the web meeting. Ask for the total price, hang up, and think it over.
• ▸If you already signed, the clock is roughly 8 days from whichever arrived first, the application document or the contract document — and a contract pitched in a web meeting may be eligible for cooling-off if it qualifies as telemarketing sales.
• ▸In Japan: consumer hotline 188 for contract trouble, police consultation line #9110 if you suspect fraud. Both are nationwide numbers.

188 is a nationwide three-digit number in Japan that routes you to your local consumer affairs centre. For a dispute about a contract or a cancellation, that is the right first call.

#9110 is Japan's police consultation line, for when you think what happened may be a crime rather than a contract dispute. If you cannot decide which to call, start with 188 — contract and cancellation trouble like this is what that line is for.

One last thing. What makes this pattern hard is that it is not built purely on lies. Reskilling and side income are real, government-backed trends, so the wording of the ad cannot tell you whether a course is worth the money.

The moment that tells you is step 3, when someone says "decide today". If the seller cannot let go of "it has to be today", that condition is itself your answer — a pitch that will not survive one night's thought is reason enough to decline.
