Bottle of Nikka Pure Malt NEED INFO!

Hello all I have recieved a gift bottle from my girlfriends father whilst vacationing in japan. They live in Yoichi, Hokkaido (Hometown of Nikka distillery, Which I went to and must say is magnificent) Anyways being Japanese as they are her father gave me a bottle of Nikka Pure Malt as a first time meeting gift. I looked on Nikka's site and was not able to find any information in their pure malt section. So I was wondering if any more learned persons could give me info on this bottle.

This is the info I can gather from the bottle itself:

Nikka Pure Malt Whisky
55.1%
Distilled in: Minami Aoyama Tokyo Japan
Age: 20 Years (Possibly)
500ml
Serial: 18J54B

If the photos dont work just let me know. Thanks for the help

I was just at the Miyagikyou distillery and they have bottlings available only on site, which it appears is what you've received.

I bought a couple of them, but the presentation in Miyagi was quite a bit quieter and as I have yet to get to the Yoichi distillery I can only assume that they do what they do separately on many of these issues. Possibly since Yoichi is the first distillery founded by Masataka Taketsuru, they thought it appropriate to make their version a bit on the fancier side?

The whisky was definitely not distilled in Minami Aoyama, but rather in Yoichi.

Very nice presentation and I love how they put 'whisky' right in the middle of all the kanji.
