What the record says
NCEI’s account, from the sources it cites.
Mar? 1699. Validity questionable. Landslide on Kyushu. Observation: Japan - Kyushu, Hizen. This tsunami reported by Gondo is undoubtedly the same as that reported by Musya (1943) and Imamura (1949) as occurring one year later [April 1, 1700] as the result of a landslide in Hizen. Musya (1943) mentions also a Hizen "yama tsunami" (mountain tsunami landslide) in Genroku 12 VI with which the Genroku 13 II landslide was confused in some sources. (reference #79)
1699, March? There was a landslide on Kyushu Island. A tsunami was observed on the coast of Nagasaki and Saga Prefectures. [Similar to the events of I.IV.1700] (Reference #414).
