Hi, I just happened to buy a tea set just like this 3 wks ago. Mine has a different flower pattern. I have 5 japanese ceramic books and each book has about 170 marks. Japan used thousands of marks. I found one mark that has a raised star w/ words Made in Japan. Usually they say Hand Painted, I never seen one that has Handmade on the bottom. Any way the raised star was registered by Aichi Prefecture in Tokoname City and made and sold from Marugo Seito Sho Inc. They were in business from 1950 and closed in 1980. Your set is not dragonware thats just a name given to pieces that have what look like snakes with dragon heads. Price guide books have these complete sets at $150-$180.00. Have a good day and that is a beautiful set!!
