DIVER OSINT CTF 2026 “F3”

Solution

A Google reverse image search did not reveal any promising clues. Searching for "竜巻災害 博物館" (tornado disaster museum) led to a Yomiuri Shimbun article about a museum in Kitakyushu. The article did not give the facility’s exact name, so I searched for "北九州 竜巻 博物館" (Kitakyushu tornado museum), which led to the official website of Space LABO, the Kitakyushu City Science Museum.

The museum’s first-floor guide lists an exhibit titled 竜巻をカガクする (Exploring the Science of Tornadoes). Comparing the exhibit’s photograph and description with the challenge image identifies it as the same location.

The location shown on Google Maps is around 33.8718, 130.8088.
