Crayon Shin-chan: Honeymoon Hurricane ~The Lost Hiroshi~ (2019) Plot Summary Explained

Hiroshi is kidnapped because he unknowingly holds the key to a hidden treasure. In Crayon Shin-chan: Honeymoon Hurricane, various factions have been searching for this treasure, and Hiroshi's connection to it only becomes clear after the kidnapping. The attack in Australia is timed to the Nohara family's arrival so the captors can isolate Hiroshi from the rest of his family and use him to reach the treasure.

Foreshadowing: Misae's excitement about the suspiciously affordable holiday package hints that the trip itself may have been arranged to draw Hiroshi out.

• hiroshi kidnapped
• australia trip
• treasure key
• nohara family

Hiroshi's role as the key is tied to his personal history and a secret tied to his identity, which is revealed only after his kidnapping in Australia. The treasure hunters and the masked man have been tracking this connection for a long time, which is why they move the moment the Nohara family lands. His importance is the central reason every faction in the movie is competing to capture him rather than going after the treasure directly.

Foreshadowing: The film hints at Hiroshi's hidden importance through Misae's surprise that he was specifically targeted rather than the family as a whole.

The masked man is the main antagonist of Crayon Shin-chan: Honeymoon Hurricane and one of three factions pursuing Hiroshi for the hidden treasure. His motives are kept ambiguous for much of the story, but he operates independently from the international treasure hunters and has his own personal stake in the secret Hiroshi carries. His presence forces Misae and Shinnosuke to fight on two fronts at once during the rescue.

Foreshadowing: His early appearance near the family's arrival in Australia hints that the kidnapping was part of a coordinated plan rather than a random crime.

Crayon Shin-chan: Honeymoon Hurricane mirrors the structure of the 1994 film Crayon Shin-chan: The Hidden Treasure of the Buri Buri Kingdom. Both stories begin with Misae winning or finding an affordable foreign trip, followed by a kidnapping, and both center on a Nohara family member being the key to a treasure. In the 1994 film, Shinnosuke himself was the key; here, that role is shifted to Hiroshi, while keeping the same family-versus-treasure-hunters formula.

Foreshadowing: The recycled premise of an inexpensive foreign trip serving as the trigger for adventure is itself a callback to the Buri Buri Kingdom setup.

Three distinct groups converge on Hiroshi because the hidden treasure can apparently only be accessed through him, making him more valuable than the treasure itself. The international treasure hunters are motivated by greed, the masked man has a more personal agenda, and the Nohara family is fighting simply to bring Hiroshi home. This overlap of motivations is what turns what should have been a relaxing honeymoon into a full-scale chase across Australia.

Foreshadowing: The fact that treasure hunters from around the world are already in Australia waiting signals that Hiroshi's arrival was anticipated.

• masked man
• nohara family chase

Hiroshi and Misae have been married and raising Shinnosuke for years but never managed to take a honeymoon trip abroad due to the cost and the demands of family life. The trip in Crayon Shin-chan: Honeymoon Hurricane is meant to finally fulfill that long-postponed dream, which is why Misae jumps on the affordable Australia package immediately. This backstory is what makes the kidnapping feel especially cruel, since it interrupts the one trip they had been waiting years to take.

Foreshadowing: Misae's immediate excitement over the cheap package suggests this is something the couple has discussed and delayed for a long time.

Shinnosuke is essential to the rescue because he is the only family member whose unpredictable, cartoonish behavior consistently confounds both the treasure hunters and the masked man. While Misae focuses on planning and tracking Hiroshi's location, Shinnosuke creates chaos that disrupts the kidnappers' operations at key moments. His role echoes the 1994 Buri Buri Kingdom film, where Shinnosuke himself was the key to the treasure rather than a supporting player.

Foreshadowing: Shinnosuke's wild antics during the plane ride and arrival in Australia foreshadow that his behavior will become a tactical advantage later.

The exact nature of the hidden treasure is not fully revealed until the climax, when the Nohara family reunites with Hiroshi and uncovers the secret tied to him. The treasure is significant enough to draw international hunters and a masked antagonist across the world to Australia, indicating it has both historical and personal value. What matters most to the story, however, is that Hiroshi is the access point to it, which is why everyone targets him instead of searching for the treasure on their own.

Foreshadowing: The masked man's obsession with Hiroshi rather than any physical location hints early that the treasure is tied to a person, not a place.

The escape comes during the climactic showdown in Australia, where Misae, Shinnosuke, and the rescued Hiroshi combine forces against both the masked man and the treasure hunters. The family's victory relies on teamwork rather than any single hero, with each member contributing in moments when the others are blocked. After defeating the competing factions, the Noharas withdraw together, leaving the treasure behind and prioritizing their reunion over material gain.

Foreshadowing: Earlier scenes of the family bickering and improvising together during small vacation mishaps foreshadow the cohesion that lets them win the final confrontation.

Misae chooses the affordable Australia package because the Noharas have never been able to afford a proper honeymoon trip abroad, and this deal appears too good to pass up. Her motivation is purely sentimental, as she wants to finally give Hiroshi and the family the overseas vacation they have always talked about. The fact that the deal is so cheap later becomes suspicious in hindsight, since it brings the family directly into the path of people hunting Hiroshi.

Foreshadowing: The unusually low price of the package is an early signal that the trip may have been arranged for reasons beyond ordinary tourism.

By the end of the trip, the Nohara family returns home with a deeper appreciation for their bond, having survived a kidnapping, a treasure hunt, and a multi-faction chase together. The adventure reinforces the franchise's recurring theme that family togetherness matters more than any material reward, which is why they ultimately prioritize rescuing Hiroshi over claiming the treasure. The film treats the ordeal as a chaotic but ultimately strengthening milestone for the family.

Foreshadowing: Misae's determination to rescue Hiroshi at any cost early in the film foreshadows the family's choice to value reunion over treasure at the end.
