Discovered this while surfing Kotaku earlier. It’s part of a series of ads starring Tommy Lee Jones playing “alien Jones” as he discovers life in Japan. It’s part of a series of ads which were used to promote Suntory Boss canned coffee.
In this ad, he lands slap bang in the middle of Akiba and takes part in a cosplay photoshoot and is taught about moe by playing rock paper scissors with a girl in a maid cafe and being fed by said girl!
This was #12 in the series and you can find others around youtube but this one was the best, although #11, the onsen ad, was pretty good too!
