TOKYO, Aug 11 (News On Japan) - A recent in-depth report captured the crucial moment when illegal drug smuggling was foiled at Haneda Airport, Japan’s primary international gateway. With the rise of inbound foreign visitors, airport customs has become an important line of defense against smuggling.
As visitors from various countries arrive, they bring with them enormous suitcases. Among the seemingly innocent items, customs officers are often faced with unexpected discoveries.
A man arriving from the U.S. explained that he brought a portable fan due to Japan’s intense summer heat and humidity. A woman from China had a bag of wet toilet paper, a product that has grown in popularity in China over the past few years.
An American couple, arriving for a jump rope competition, brought an unusual item: jump ropes, as the wife is a member of the U.S. national team.
However, amid such surprises, the growing issue of "prohibited items" and "drug smuggling" has become more frequent.
At Tokyo Customs’ Haneda Airport inspection area, officers and narcotics-detection dogs are always on alert after travelers pass through immigration.
One man arriving from Vietnam had three large suitcases. When the officer requested to check the contents, the man claimed not to know the lock combination. After failing to open the luggage, the officer used an X-ray scanner, revealing block-like shapes inside. Upon breaking the lock, they found a large quantity of cigarettes—about 30,000 cigarettes, in fact—well beyond the tax-free limit of 200 per person.
The tax imposed for the excess was approximately ¥420,000, leading the man to claim the cigarettes weren’t his, despite them being in his possession.
A reminder to all travelers: Smuggling prohibited items or excessive goods can lead to severe penalties, including up to five years in prison or a fine of up to ¥10 million.
Elsewhere, a serious situation unfolded at another inspection lane. Customs officers discovered a suitcase with no identified owner, prompting an immediate investigation. The bag belonged to a 20-year-old American who claimed to be visiting Japan for a brief stay. Though the man only had a backpack, his suitcase contained large amounts of maple syrup, along with 18 bottles, all containing THC (the active component of marijuana).
The total weight of the drugs was 17kg. The man was arrested at his hotel for violating Japan’s Customs and Narcotics Control Laws.
With the surge in illegal drug smuggling attempts, authorities are stepping up their vigilance. In 2024, there were about 50 drug smuggling cases at Haneda, and as of June 2025, there have already been over 40 cases.
One woman arriving from Brazil tried to conceal the drugs inside her body. After a medical examination, over 100 small bags of cocaine worth approximately ¥25 million were discovered.
Haneda Airport’s role as Japan’s final defense against illegal drug smuggling continues to grow in importance as authorities face increasing challenges in curbing this growing problem.
