The list is very incomplete; information on early typhoon seasons is patchy and relies heavily on individual observations of travellers and ships.
[2] Two fierce typhoons struck Japan in August and September 1850; the first one, a powerful storm comparable to the 1828 Siebold typhoon, struck Buzen Province in northeastern Kyushu and rolled through the Chugoku region on 18 August, destroying 459 houses in the Akizuki Domain (now central Fukuoka Prefecture) alone; and the second one affected much of western Japan between the Kyushu and Chubu regions on 12 September.
The storm stalled off the east coast of China, and when the Eament encountered the eye, it reported a barometric pressure of 28.14 inHg (953 mbar).
The ship-based observations suggest a spatially enormous, slow moving tropical storm (or typhoon) in the East China Sea, and force-6 winds continued to be reported through 31 July.
[1] A powerful typhoon struck Edo (modern-day Tokyo) on 23 September[7] and briskly swept across eastern Japan through the 24th.
