“Airplanes Are Made of Dogs”: How a Bizarre Reading Comprehension Question Sparked a Viral Linguistic Debate in Japan

A seemingly absurd phrase, “Airplanes are made of dogs,” has recently taken Japanese social media by storm. The frenzy originated from a reading comprehension test question highlighted in recent media reports addressing concerns over declining literacy skills among Japanese children. The question asks whether the sentence “makes sense.” While standard reasoning dictates that the expected answer is “No,” the prompt has triggered an explosion of linguistic debates, comedic banter, and imaginative theories across the internet.

A major catalyst for the viral explosion was a post on social media by popular voice actor Junichi Suwabe. Offering advice to young students, Suwabe warned: “If asked whether ‘Airplanes are made of dogs’ makes sense, the correct answer on a test is ‘No.’” He then playfully referenced an iconic incantation spoken by Archer, a beloved character he voices in the anime Fate/stay night—“My body is made of swords” (originally translated as “I am the bone of my sword”)—adding, “If I were the examiner, I’d give you full marks for it, but you will definitely get it marked wrong on a school exam, so be careful!” His humorous post spread like wildfire, quickly driving related keywords to the top of trending topics.

The discussion quickly deepened into a serious exploration of semantics and language logic. Many commenters took an analytical approach, pointing out that “grammatical correctness is not the same as semantic coherence,” or arguing that “a false factual proposition is different from an incomprehensible sentence.” Meanwhile, others took a more creative angle, suggesting that “it could work perfectly fine within a sci-fi or metaphorical context,” or joking that “if Studio Ghibli can have a Catbus, a Dog Airplane isn’t out of the realm of possibility.” Some users even went as far as inventing fantasy spell chants and epic incantations centered on the phrase.

Beyond serving as an amusing internet meme, the bizarre test item has sparked deeper contemplation among the public: Does reading comprehension simply mean interpreting statements literally without overthinking, or does it mean grasping deeper contexts? What truly qualifies a sentence as “making sense”? Through humor and creative wit, social media users have turned a simple school assessment into a profound debate on the nature of language and communication.

The Context

In Japan, the issue of “declining reading comprehension” among young students has become a recurring topic of national concern. This anxiety was notably amplified following the release of diagnostic reading tools like the Reading Skill Test (RST), pioneered by cognitive scientist Noriko Arai to evaluate whether students can accurately process factual and logical relationships in basic text without confusing them with artificial intelligence-like superficial pattern recognition. Such tests often include seemingly obvious questions—like asking if a factually impossible statement “makes sense”—to determine if readers can separate grammatical structure from factual reality. When these diagnostic examples leak into popular discourse, they often clash with the playful, anime-inspired culture of Japanese net users, who delight in deconstructing language rules through pop-culture references, wordplay, and hypothetical scenarios.
