Zaisho

Zaisho is the name of a stony-iron pallasite meteorite whose fall in Japan in February 1898 was recorded by observers on the ground.^[1][2] Zaisho made landfall in the city of Kami, located in the prefecture of Kōchi on Shikoku Island.^[3] 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.^[1][4][5] Notably, Zaisho is also one of two confirmed meteorite landings to take place on the island of Shikoku,^[1] and as of 2019 it remains one of only four known pallasite falls, along with Marjalahti, Mineo and Omolon.^[4] Currently, access to Zaisho is not available to the public as the main mass of the meteorite is being held in a private collection.^[4]
