Best place to buy Pumpkin Pie in Tokyo?

Hey, so I'm a Brit who is going to his first Thanksgiving with some American friends. I have been tasked with bringing a pumpkin pie to the dinner.

Any recommendations as to where I could get a decent pumpkin pie?

Thanks in advance!

Although I'm not be bought.
It sells in Anna Millers.

Costco also sells pumpkin pie during this time, if you can find a store near you.
