Tokyo Olympics

I found this on the Tanaka web site.

I hope it helps



In 1962, two years before the Tokyo Olympics, the Tokyo Olympics Fund Foundation asked Ichiro Tanaka, the second president of our company and the president of the Precious Metals Association, to fabricate the Olympic commemorative medals. The president readily agreed to the request and was excited about the project. Unfortunately, he suddenly passed away in 1963, and Junichiro Tanaka, the third president, succeeded to the business.

In October of the same year, Junichiro Tanaka took the first step toward fabrication by establishing the Tokyo Olympic Commemorative Medal Association.
The association fabricated blank medals and the Ministry of Finance Mint Bureau marked the design on both sides. The association invited the Bureau to join the project because of its public nature. Three types of medals --gold (18-karat gold), silver, and copper-- were fabricated and the sale prices were 5,000 yen, 800 yen, and 200 yen, respectively.
On the day of release, people lined up in front of stores, and the medals enjoyed brisk sales as premium items.
The first medal fabricated was placed on Ichiro Tanaka's grave in appreciation of his efforts.

Thank you both. I've no doubt that this was a commemorative but the finish is bothering me. The colour is very flat on the scans, in hand it has a beautiful buttery gold colouring. Ob & rev look to be possibly gold plated, the edge I'm not so sure. Powder coated perhaps.
Either way it's good.
