In a 2015 Diet budget committee session, lawmaker Antonio Inoki — a legendary professional wrestler turned politician — pressed Defense Minister Gen Nakatani directly on Japan's UAP response capability and policy. Nakatani's responses, made on the official parliamentary record, confirmed that Japan Air Self-Defense Force jets scramble when unidentified objects enter Japanese airspace and cannot be identified, and that there was no specific official government policy defining what UAP were or how they should be treated if encountered.
The Nakatani confirmation was significant as a formal parliamentary statement because it established on the Diet record that JASDF intercepts of UAP were a real and ongoing operational reality — not a hypothetical possibility but an existing practice. The absence of a specific government policy for dealing with the phenomenon — acknowledged by the Defense Minister himself — highlighted a gap in Japan's national security framework that subsequent administrations would begin to address.
Antonio Inoki's decision to raise the UAP question in a budget committee session reflected both his personal interest in the phenomenon and a calculated political judgment that the question had sufficient public and security relevance to warrant parliamentary time. Budget committee sessions are among the most high-profile parliamentary proceedings in the Diet, with extensive media coverage and formal record-keeping, making Inoki's interpellation a maximally public venue for establishing the UAP issue on the official record.
The 2015 exchange between Inoki and Nakatani contributed to a gradual accumulation of Diet UAP record that would eventually lead to more formal policy development. By 2020, Japan's Defense Ministry had established a formal UAP working group; by 2022–2023, JASDF UAP scramble data was being included in annual defense white papers. The 2015 Diet session represents an early stage in this institutional progression, when UAP was still treated as a novel and somewhat surprising policy question rather than an established defense planning concern.
Japan's engagement with the UAP issue through formal parliamentary channels — Diet interpellations, ministerial responses, and annual defense reporting — provides a model of democratic transparency on the phenomenon that contrasts with the more opaque handling by many other governments.
