Tokugawa Memorial Foundation

How can I send you an email? I cannot read Japanese.
About 40 years ago I purchased a superb bronze Japanese urn. It weighs about 12 kgs. Its feet (3) are beautifully cast bulky males.
The urn has what appears to me to be a Tokugawa mon on it.
I wondered if you could tell me more about it and whether it really belongs in Japan.
I bought the urn after it had been passed in 3 times at an auction. I was the top bidder each time and finally did a deal with the auctioneer. He told me the urn had been in the hands of a collector for many years. Although I have no reason for thinking this I did wonder if it arrived in New Zealand after being looted by occupying forces after World War 2.
Do hope you can help me.
