In Search of a Specific Tea Shop? and Tea

Hello; Could You Folks Help Me Locate This Tea Shop Near Nagoya ,Japan.
I Need Either a Website or A Address to Request a Order to Purchase Tea From Them.
I was In Japan in 2005 . I Know Things Might Have Changed .
I tried Several Times to Make Contact with The Mall or The City of Nagoya .All of My Letters Were Returned as Undeliverable .
If You Could Help < I would Be Extremely Grateful .
Thank You,,,,,,,Howard

This would appear to be the place. It doesn't look to me like they are set up to handle mail orders from overseas, though.
