Their free ride came with a steep price.

Two American women allegedly jumped at the chance for an all-expenses-paid trip to Japan — but they had to lug nearly $1 million worth of weed through Tokyo customs to get it, according to media reports.

Cartron Jamere Bourbon Castillo and Jocelyn Dizon Natividad Patrin, both 25, were busted after allegedly flying from New York to Tokyo’s Haneda Airport on Sept. 5 with a whopping 66 pounds of dried marijuana stuffed into two suitcases, said the Tokyo Reporter.

The staggering haul — reportedly worth about 150 million yen, or $970,000 — was divided among dozens of packages.

The women “conspired with someone else whose name is unknown,” the police spokesman told Agence France-Presse (AFP), which reported that they claim to have received instructions from a man they met on social media but never met in person, reported the news outlet.

In return for the smuggling job, they were offered to cover the airfare and accommodation, as well as a financial reward, reports said.

During police questioning on suspicion of violating the Narcotics Control Act for smuggling and the Customs Act, Castillo admitted to the allegations, telling investigators it was too tempting to pass up, according to the Reporter.

“I accepted the job after hearing I would get paid,” she reportedly told police. “I was attracted by the idea of being able to go to Japan for free.”

Meanwhile, Patrin has denied the charges, telling police she “didn’t know that cannabis was inside” the suitcase, the Tokyo Shimbun reported, citing unnamed police sources.

Footage aired by Nippon TV, showed authorities displaying package after package of the alleged cannabis following the bust.

Authorities have not publicly identified the alleged organizer or the final destination of the drugs.

The daring duo picked the wrong country to land in.

The Land of the Rising Sun is notorious for its zero-tolerance approach to illegal drugs and its powerful criminal justice system — the conviction rate is reported to hover around 99%.

Importing cannabis carries a maximum sentence of seven years in prison, while importing it for profit can carry a maximum of 10 years and a fine of up to 3 million yen, or about $19,500.
