Zaisho is the name of a stony-iron pallasite meteorite whose fall in Japan in February 1898 was recorded by observers on the ground. Zaisho made landfall in the city of Kami, located in the prefecture of Kōchi on Shikoku Island.Hudson Institute of Mineralogy. (2016). Zaisho meteorite, Kami City, Kochi Prefecture, Japan. Mindat.org. https://www.mindat.org/loc-262253.html Zaisho weighs approximately 0.33kg (12oz) and exhibits a rare composition of primarily iron rich phosphoran olivine, and pyroxene. Zaisho also contains traces of stanfieldite, farringtonite, troilite, schreibersite, chromite, and mg-phosphate, albeit in smaller amounts.Shima, M., Okada, A., & Yabuki, H. (1980). Mineralogical and petrographical study of the Zaisho meteorite, a pallasite from Japan. Zeitschrift fuer Naturforschung Teil A, Physik, Physikalische Chemie, Kosmophysik, 35(1), 64-68. Notably, Zaisho is also one of two confirmed meteorite landings to take place on the island of Shikoku, and as of 2019 it remains one of only four known pallasite falls, along with Marjalahti, Mineo and Omolon.{{cite journal |last=Buseck|first=Peter R.|author2=Jim Clark |title=Zaisho a pallasite containing pyroxene and phosphoran olivine|journal=Mineralogical Magazine|date=June 1984|volume=48|issue=347|pages=229–35|url=http://www.minersoc.org/pages/Archive-MM/Volume_48/48-347-229.pdf|access-date=8 January 2013|bibcode=1984MinM...48..229B|doi=10.1180/minmag.1984.048.347.06|citeseerx=10.1.1.608.9261}} Currently, access to Zaisho is not available to the public as the main mass of the meteorite is being held in a private collection.
