Consumer Protection Quiz | Spotting Dark Patterns, Subscription Traps, and Misleading Shopping Displays — Set 7
Problem 1
An online store displays “Discount ends in 09:59.” You wait for the timer to expire and reload the page. It starts again at 09:59, and the price has not changed. What is the most appropriate interpretation and response?
View explanation
A timer that returns to the same duration after expiring may be designed to hurry a purchase rather than represent a real deadline. The timer itself proves neither a low price nor scarce stock. Set aside the induced urgency and verify the total price, your need, and the sales terms through other information.
Problem 2
You intended to select only an airline ticket, but the cart immediately before payment includes travel insurance costing ¥3,000, with its box checked by default. You have not read the coverage. What is the most appropriate action before confirming?
View explanation
A preselected add-on can enter the purchase without an affirmative choice by the customer. Appearing in the total is not the same as informed selection. Review the coverage, possible overlap with insurance you already have, and your need for it; if unwanted, remove it and verify the revised total.
Problem 3
A ticket comparison screen lists Company A at ¥8,000 and Company B at ¥8,600. At the final purchase step, Company A adds a mandatory ¥1,200 “ticket handling fee,” while Company B's amount remains unchanged. Which price comparison is most appropriate?
View explanation
Adding a mandatory charge late in the process can distort a comparison based only on the initial price. Whatever its label, an unavoidable fee belongs in the total burden. Under these conditions, A costs ¥9,200 and is ¥600 more expensive than B on price, although seat and other terms should also be compared.
Problem 4
An in-game item costs 1,200 coins. Coins are sold only in packs of 700 for ¥980. Your current balance is zero, and you cannot buy partial packs or obtain a refund. What are the minimum cash payment and remaining balance after buying one item?
View explanation
One 700-coin pack is insufficient, so you must buy two packs and obtain 1,400 coins. The cash payment is ¥980 × 2 = ¥1,960, leaving 200 coins after the purchase. Evaluate both the purchasable pack size and the unusable remainder, not merely the item's displayed coin price.
Problem 5
You joined a video service online within minutes, but cannot find a cancellation link. Its terms say cancellation is by telephone only from 11 a.m. to 1 p.m. on weekdays. The number is buried in a note on another page, and the call involves a lengthy retention pitch. What is the most appropriate response?
View explanation
Hiding the exit and imposing a narrow telephone window and lengthy retention process can obstruct cancellation. Canceling a card may not resolve the underlying contract. Preserve the terms and contact history, attempt the published process, and seek consumer advice rather than ignoring further charges if the process cannot be completed.
Problem 6
On a subscription cancellation page, “Keep my benefits” appears as a large blue button, while “End my subscription” is a small, pale link at the bottom. If your decision to cancel has not changed, what is the most appropriate approach?
View explanation
Size and color can draw attention toward the provider-favored choice to remain subscribed. Do not treat visual prominence as a recommendation. Read the labels and the resulting screen, verify the completion page or email, and do not assume that simply closing the page completed cancellation.
Problem 7
A learning app prominently advertises “7 days free.” Small text says, “¥12,000 annual fee charged in one payment on day 8. To stop renewal, cancel by the day before day 7,” and a payment method is required at sign-up. What is the most appropriate decision before enrolling?
View explanation
A free trial may automatically convert into an annual contract. Here, the charge date and cancellation deadline do not coincide, which is especially important. Do not rely on the prominent word “free”; understand the continuation terms and decide whether you can manage the required cancellation deadline.
Problem 8
On an online-store registration page, “share purchase history with partners” and “receive marketing email” are checked by default, separately from the shipping address. The page states that neither is required to buy the product. What is the most appropriate response?
View explanation
Address use for fulfilling the purchase differs from optional marketing or disclosure to partners. A default selection does not establish necessity or informed agreement. Read each purpose and reject unwanted optional uses without confusing that decision with refusing information genuinely needed for delivery.
Problem 9
A cosmetics company in Japan pays an influencer and specifies the post's wording and photos. The post has no indication that it is advertising or PR and appears to be the influencer's independent opinion. As of October 2026, which explanation is most appropriate?
View explanation
In Japan, an advertisement whose content a business helped determine is covered when consumers have difficulty recognizing it as advertising. The regulated party is the advertiser that supplies the product or service. Whether individual claims are true is a separate issue from disguising paid advertising as an independent opinion.
Problem 10
A comparison site claims to provide “completely neutral rankings unaffected by advertising,” and only the top-ranked communications service has a prominent application button. The operator's information reveals that rankings mainly reflect the referral fee earned for each sale rather than a quality assessment. What is the most appropriate response?
View explanation
A ranking based on compensation but presented as neutral can disguise an advertising interest as independent evaluation. That does not by itself prove every listed fact false. Check how the ranking is funded and calculated, then compare the actual terms using official information and other independent sources.
