Today, we will use the same logic to see if the data of ASM placement in Japan and Korea will be different from the situation in the United States.

The number of active ASM products in Japan and Korea so far is 7,611 and 4,532 respectively, which is less than the number of products in the US (16,719), mainly due to the difference in the number of apps they have online in the App Store.
