Manufacture of Other Marine Products 
/ 
Other manufactures from marine products included vitamin oils 
from fish livers, pearls, coral and shell buttons and iodine potassium 
and other chemicals. The me.nnfacture of leather from shark was another 
minor industry which had developed in recent years. 
The cod liver oil industry, the earliest of the vitamin oil indus¬ 
tries was some years ago practically confined to Karafuto where 10 small 
plants accounted for 90 percent of the production. The remainder was 
produced in a few small islands off Hokkaido. 
Recent information concerning the manufacture of vitamin oil is 
fragmentary. Tuna liver oil for vitamin concentrates was reported produced 
in Muroto, Kochi Prefecture and three small plants making vitamin oils 
were operating in the Tokyo area. 81 J
