to paraphrase:
Moriya (Ultralight) Airstrip was evidently founded in 1985 on the floodplain of the Tone River, on land leased from private owners. Primary users were the Moriya Flying Users Club (about 40 general aviation enthusiasts), as well as helicopter operators Asahi Koyo and Japan Flight Safety for training purposes. However, the land was purchased from the previous owners by the Tone River Office (Kuki, Saitama) for use as a flood easement - Inatoi Reservoir (which is now visible adjacent to the remaining N-S runway).
2022 Update
Unlike its twin to the east-southeast, this ultralight airport continues to thrive for now.
Update 2022
N/S runway still appears intact, but hangar structures appear to have been demolished.
Closed
Area being redeveloped. E-W runway already mostly destroyed in recent sat maps, N-S runway remains.
Confirmed closed 2000

Per this excellent Japanese airfield blog, Moriya (MFOC) Airfield was closed in 2020 due to damage from the previous year's Typhoon No 19.
