Yea I didn't know what that building was until I saw Tokyo Drift. Then I was like SO THATS WHAT THAT WEIRD FACTORY LOOKING THING IN THAT ONE AYU COMMERCIAL WAS!!!
AHA I THINK THAT GUY'S SAYING KURIHIROI!! I swore that's what I heard. And then I looked it up and only found kurihirogeru, so I thought maybe the hiroi part is the same hiroi as the hiroi = spacious. I googled it:
http://www.spa-yunogo.or.jp/kurihiroi.html and huzzah kurihiroi is a word! I check out another site...
http://www.boxos.com/kurihiroi.html and I noted that there's a kanji next to the kuri kanji...I decided to check hiroi to see if there's other meanings...and lo and behold there's that kanji...hirou = to gather/pick stuff. Therefore kurihiroi = activity of chestnut picking. Comes from kuri wo hirou. Hirou is changed to its stem-form hiroi, a kinda nounish form.
Oh crap I just figured out the old dude doesn't say "kotoshi mo iku." Only the couple speaks.
So...here's my two cents:
Couple waiting at carpark for their car.
kotoshi mo iku? kurihiroi (shall we go again this year? chestnut picking?)
e~? kuri? daisuki!!! (chestnuts? i love chestnuts/chestnutpicking!!)
Out comes Ayu eating awesome chestnut snack instead of the guy's car. The couple are like "...wtf just happened there?" Funny cause no car, but chestnuts are there. And pure randomness of course lol.
