Thank you for even more useful information. I knew the suicide verb (from photo of cup kanji on Google Translate) was not to be taken literally for a commemorative cup but I really want to get this right and my kanji is woefully rusty.
Dad had me auction nearly 100 saki cups on eBay before he died a few years ago and I listed them one by one. He got a kick out of seeing how much they had appreciated over time and how competitive the bidding would become. At one point most of the saki cups offered on eBay were our's. I still see them all over Google images.
I learned a great deal about figuring out kanji on cups during that year and surprisingly, many of them returned home to Japan. Everything was gobbled up but his collection of medals, swords, flags, and sennenbari were the craziest auctions, to say the least. Almost half of the swords went to China. I found that very interesting— one gentleman bought nineteen katana at once, all in separate but very competitive auctions. I collect the belts so dad couldn't convince me to sell many of those. You name it, he had it. It was fun to see him enjoy those auctions so much.
