Sakuma Seika, since my most trusted source, wikipedia, didn't have much information available, and the information that was there led to another website then the website that was on the back of the package I had. I am grateful that I was able to find some information on this candy on the Just Hungry site in English, because google translate didn't help much when I was browsing the manufacturers site.What didn't make it easier was that there are actually two companies that are called Sakuma Seika and they both produce candy. It seems that they are companies from rivals within the same family, so I found out thanks to the information that Maki provided.
Sakuma Ichigo Milk Candy, is a hard Japanese candy that is more commonly known as Sakuma Drops. The original Sakuma drops come in a reclosable can and have a layer of sugar on them. The Ichigo Milk Candy are another type of hard candy that Sakuma Seika makes. They come in a plastic package and are individually wrapped. The wrapping has strawberries on them since Ichigo means strawberry. (I actually knew this since I pick up some words of Japanese when watching anime). My package contained 115gr of candy.
Since I got these as a gift, I do not know where they were bought, but the price sticker says they did cost €3.89.
