J:COM’s commercials featuring the popular mascot character “Zaq”!

This time, we’ve carefully selected some of the most popular commercials from the bunch! Please take a look.

First, get to know J:COM! “I’m totally obsessed (Korean Wave)” version

J:COM CF_Overheated Korean Wave Version (Autumn 2009)

This commercial aired in 2009 and is titled “First, Get to Know J:COM! Swooning Over K-Dramas Edition.” It features Kyoko Uchida soaking in a bath and becoming entranced by sweet lines from Korean stars.

Maybe because it was broadcast in 2009 (and it’s now 2019), it made me feel the passage of time a bit, but what really stuck with me was Kyoko Uchida’s beautiful décolletage.
