A reader recently asked for a simple explanation of Japanese measuring spoons for cooking.
There are three basic measuring spoons in Japan, according to the Shogakugan Japanese dictionary. The two more commonly used of those three are the “osaji” (literally “big spoon”), which is 15 ml, and the “kosaji” (literally “small spoon”), which is 5 ml. The third is a less-used and nameless 2.5 ml measuring spoon.
The osaji is nearly equivalent to the U.S tablespoon, which is said to be approximately 14.79 ml. Similarly the kosaji is roughly the same as a US teaspoon, which is about 4.93 ml.
When reading a Japanese cooking recipe, chances are the amount of seasonings need will be listed in osaji and kosaji.
On a side note, Japanese measuring cups are 200ml, as compared with US measuring cups which are said to be about 236.6 ml. Also, one cup of uncooked rice in Japan, called a “go”, is about 180 ml.
If you are looking for Japanese recipes, one of the most popular sites in Japan is Cookpad. (Sorry, but it’s all in Japanese.)
