Scam catalogue
10 adult-travel scam patterns that recur across the 11 countries this site covers, with the regions in which each dominates, how each works, how to defuse, and how to report. Patterns are listed roughly in order of how often they are reported, with the financial-loss patterns first and the legal-exposure patterns last.
Bottakuri (Japanese bill-padding bars)
Japan — Tokyo (Kabukicho, Roppongi), Osaka (Namba), Sapporo (Susukino), Fukuoka (Nakasu)
How it works
A street tout (often friendly, often speaking some English) approaches a foreigner in a nightlife district and offers to lead them to a bar 'with the best girls' or 'with free first drinks'. The bar has no posted prices, fake menus appear, drinks arrive uninvited. At the end of the evening a bill of ¥80,000 to ¥300,000 is presented; a credit-card machine appears with two large men beside it; refusal to pay is met with implied threat. The card is typically also skimmed during the transaction.
How to avoid
Never follow a street tout in Japan. Every legitimate Japanese venue is found by address or website, not by solicitation. If prices are not posted, leave immediately. If you have already entered, order nothing and leave. If you have already ordered, ask for the bill before more drinks arrive. Carry cash and leave the bulk of your cards at the hotel.
How to report
Tokyo Metropolitan Police bottakuri hotline (in central Tokyo, the nearest koban). The TMP runs continuous signage campaigns in Kabukicho about this specific pattern. Embassy can assist with documentation for an insurance claim.
Bar-fine padding + 'lady drinks' (Philippines, Thailand)
Philippines (P. Burgos and Makati in Manila, Angeles City Walking Street, Cebu); Thailand (Pattaya, Phuket, parts of Bangkok)
How it works
Posted bar fines and drink prices are honoured at the start of the evening. As the night goes on, additional 'lady drinks' (compulsory tips to bar staff for sitting with the customer) accumulate, often without being announced. The final bill arrives after several rounds at multiples of the quoted total. Refusal at this point is met with bouncer pressure and threats to summon police.
How to avoid
Pay round-by-round rather than running a tab. Check each chit as it arrives. Confirm in advance whether the worker's drinks are charged to your tab (they typically are; the rate is the question). Set and stick to a hard cash limit before entering. Leave bank cards at the hotel.
How to report
Thailand: Tourist Police 1155 (English-speaking) — the request to call them often defuses the situation in real time. Philippines: PNP Tourist Police hotline; in Angeles City specifically, the PNP has a dedicated Tourist Assistance Office on Friendship Highway.
KTV / room-salon bait-and-switch
Korea (Gangnam, Itaewon), Taiwan (Taipei Linsen North Road, Kaohsiung), Vietnam (Bui Vien HCMC, parts of Hanoi), Indonesia (Jakarta nightlife districts)
How it works
Quoted hourly room rate is honoured; at the end of the evening, charges appear for per-hostess time, per-drink (including hostess's drinks at multiples of menu price), per-fruit-plate, per-song, and a 'service' or 'set-up' fee. Bill multiplies 5-10× quote. Pre-paid card credit on house cards adds a captured-deposit dynamic.
How to avoid
Ask in advance — in writing or with a photograph of the posted menu — what is included in the hourly rate and what is extra. Pay for one hour at a time, in cash, and renegotiate explicitly at each renewal. Do not put money on a house card. Never accept 'special' or 'VIP' upgrades without separately posted prices.
How to report
Korea: Korean Tourist Helpline 1330 (English-speaking, 24/7). Taiwan: Tourist hotline 0800-011-765. Vietnam: tourism police in HCMC (District 1 Tourist Information Center can refer).
Fake-police shakedown
Cambodia, Vietnam, parts of Indonesia (Bali especially); also documented in Thailand and the Philippines
How it works
Two or three men approach the foreigner outside a bar or hotel; one shows a 'police badge' (often a hotel-style ID card with a Chinese-character or English-text police-style design); they claim a violation of vice / immigration / morality law and demand a 'fine' in cash to avoid being taken to the station. The framing leverages the customer's awareness that they may have actually done something prosecutable.
How to avoid
Request to see warrant card and request to be taken to the nearest police station. Genuine police will produce ID and either escort or summon a marked vehicle; fake police collapse at this point. Do not pay cash in any 'on-street resolution' scenario. In Cambodia, ask explicitly whether they are tourist police and request to call your embassy. In Vietnam, request that uniformed officers be summoned.
How to report
Local police station (the real one). Embassy after the fact. The pattern is well-documented in Cambodia and Vietnam and embassies treat it as routine.
Drink-spiking + theft
Indonesia (Kuta/Seminyak in Bali especially; also Jakarta nightlife); Vietnam (Bui Vien HCMC); Thailand (occasionally documented in Bangkok and Phuket)
How it works
A drink is spiked with a benzodiazepine (commonly chlorpromazine, ketamine, or rohypnol equivalents); the customer's wallet, phone, and cards are removed; cards are sometimes used immediately at nearby ATMs. In Bali specifically, methanol-tainted local arak (the 'Bali methanol' incidents) is a separate but related risk that has killed tourists.
How to avoid
Never leave a drink unattended. Watch drinks being poured. Avoid arak and other unlabelled spirits in Bali; the methanol risk is real and recurring. Travel with a hotel-safe stash of cash; carry only what you can afford to lose. Tell someone (hotel desk, travelling companion) where you are going each evening.
How to report
Local police; embassy for travel documents. The Bali Provincial Health Office tracks methanol-poisoning incidents.
ATM card skimming
Thailand (Sukhumvit Bangkok, Walking Street Pattaya, Patong Phuket), Philippines (Manila), Indonesia (Kuta Bali), Cambodia (Phnom Penh riverside), occasionally Korea (Itaewon, Hongdae)
How it works
Freestanding ATMs in or near tourist-bar zones have skimming devices fitted over the card reader and miniature cameras above the keypad. Cards are cloned; PINs captured; counterfeit cards are then used in the same country or in cross-border ATM networks. Often paired with bottakuri / bar-fine charges that put cards in scammer-controlled card machines.
How to avoid
Use ATMs inside bank branches (during business hours) or inside large convenience-store chains (7-Eleven in Thailand and Japan; FairPrice in Singapore). Avoid freestanding ATMs in entertainment strips. Cover the keypad with one hand while entering the PIN. Use a card with low daily ATM limit. Enable instant transaction notifications.
How to report
Card-issuing bank (their fraud line, not the local branch). For a paper trail, file a local police report — required by most travel-insurance policies and by chargeback procedures.
Online-booking deposit disappearance
Japan (delivery health), Korea (online 'condition' platforms), Taiwan (yuán jiāo apps), regional generally
How it works
A deposit is taken via a local payment platform (LINE Pay, Kakao Pay, PayPay, bank transfer); the worker never arrives; the contact disappears. In some variants the deposit-taker is one person, the no-show is another, the listing is yet another.
How to avoid
Do not pre-pay deposits via apps for in-person meetings. In Japan, established 'delivery health' establishments do not require pre-payment. In Korea and Taiwan, deposit demands are the marker of a scam, not a marker of legitimacy.
How to report
Local police; the payment platform's fraud channel. Recovery is rare; the value is the paper trail for the platform's pattern-matching.
The 'sick mother' / long-term grift
Thailand, Philippines, Cambodia, Vietnam, Indonesia (regional)
How it works
A worker met in a bar develops a personal relationship with the customer over a series of visits or via messaging. Family expenses appear: a sick mother, a sibling's school fees, a debt to a moneylender, a buffalo that died. The asks escalate gradually. In the mature variant, the worker has parallel relationships with several other foreign men running the same script.
How to avoid
Treat the relationship as transactional with capped costs. The expenses described may be real but the framing is scripted. Long-term cash transfers to someone you have known only in a bar context have produced more reported financial loss to foreign men in Southeast Asia than any other single pattern.
How to report
There is no fraud here in most cases — the loss is voluntary. Embassies cannot help with grift losses. Financial advice from someone outside the relationship is the only useful intervention.
Massage-parlour 'extras' bait-and-switch
Malaysia (KL, Penang), Indonesia (Bali, Jakarta), Thailand, Taiwan, Hong Kong
How it works
A massage is booked at a posted hourly rate. Once the customer is on the table, additional services are offered with opaque pricing; in some venues the masseuse asserts that the previously-quoted rate covered only the room, not the actual massage. Walking out at this point is met with bouncer pressure.
How to avoid
Confirm in writing or by photograph what the posted rate covers before paying or undressing. If 'extras' are not listed on a menu they are not legally priced. Walk out before unbalanced exchange begins — once money or clothing is on the table the dispute leverage shifts.
How to report
Tourist police where they exist. Cards used at parlour card machines should be cancelled and re-issued.
Compensated-dating sting (customer-side)
Japan, Korea
How it works
A meeting is arranged online with someone who turns out to be under 18 (often misrepresented in the listing or by the introducer). The customer's belief about age is not a defence in most prefectural ordinances in Japan or under Korean law. The encounter — or a recorded conversation around it — is then used either by police (in genuine stings) or by the introducer (in extortion variants).
How to avoid
Never use compensated-dating platforms. If you do, age verification is the customer's risk; treat any age claim under 25 in a photo as a potential trap and walk away. In Japan, prefectural ordinances apply strict liability; in Korea, the 2020 'Nth Room' enforcement intensified focus on this category.
How to report
If actually targeted in a sting and detained, this is an /emergencies-page scenario: request consular notification immediately; do not make statements; engage local English-speaking legal counsel.
The common defences across all patterns
- Never follow a street tout, anywhere in this region.
- Never enter a venue without posted prices.
- Pay round-by-round; never run a tab; never put money on a house card.
- Carry cash, leave the bulk of your cards at the hotel, set hard limits.
- Use ATMs inside bank branches, not freestanding machines on tourist strips.
- If a "police officer" demands cash on the street, ask to be taken to the station.
- Treat any in-person relationship that begins in a venue as transactional with capped costs.
