Inage Civil Aviation Commemoration Center, Former aviation museum in Mihama-ku, Chiba, Japan

The Inage Civil Aviation Commemoration Center was a museum in Inage Seaside Park, Mihama-ku, with a site area of 3,600.40 m² and a total floor area of 443.15 m². Its exhibits included a restored Naihara-shiki No. 4 "Hōgō" biplane, a restored "Primary" glider, a Space Shuttle model, ten solid models, a simple wind tunnel, and explanatory panels.

The museum opened in 1989 and documented Japan's civil aviation development over three decades. It closed in 2018, marking the end of its role as a repository of regional aviation history.

The museum presented detailed exhibitions highlighting the progression of Japanese civil aviation through photographs, models, and technical documentation.

The museum stood inside Inage Seaside Park at 7-2-2 Takahama, Mihama-ku, Chiba. It was reached by bus from Inage-Kaigan Station on the JR Keiyo Line or Inage Station on the JR Sobu Line, getting off at Takahama-Minami Danchi. From the Asama Shrine intersection on Route 14, the site lay about 2 km toward the sea. Opening hours were 9:00 to 17:15, extended to 18:00 in July and August; it closed on Mondays, or the following day when Monday was a holiday, and over the New Year period.

The museum displayed a restored Naiharashiki No. 4 "Hōgō" biplane, the type flown at Japan's first private airfield, which opened at Inage in 1912. The restoration flew again on 9 November 1987, 75 years after the original.
