It definitely came from Japan. But they usually put on those paper white and blue tags, usually with the handwritten kanji.
And then when EU traders unload it, they don't know what the variety is.
Of course Japanese aren't immune to mislabeling, but that label would have said what it is.
I am just wondering if they sold it as 'Yumehanabi' because the label stated 夢花火
If you are interested in some more pictures of Yumehanabi:
今日（8日）は天気予報が大当たりで午後から大雨でした。おかげで昨日からの農作業は中途半端なままです。マー、雪にならないだけマシなのですが、今年は雨が多く冬晴れが長続きしませんね。節分を過ぎると徐々に陽が高くなり、日差しも強くなります。皐月の根が動き出すまであと少しです。そろそろ植替えの準備を始めるかな～。掲載品種の月別一覧は・・・こちら・・・・・・・・・・ありらん（好月の枝変り）中輪・深切れ咲き、底白、爪紅、紅色無地底白と紅色無地底白爪紅☆2010年、上野に登録されています。花芸は少なく最新版の「さつき大図鑑」では紅色系底白に分類されています。底白は薄っすらと紅色が入り純白ではないようで...

And a good Koun picture:
Personally, I would not trade or sell cuttings from this one as 'Yumehanabi'. For me, a plant should come labeled or IDed. And the actual flowers should match the images so it convinces me the ID is accurate. I may make an exception when something just very clearly is a certain cultivar because I know it well and it is distinct.
What would satisfy me is that for example this one came from Crespi Bonsai. And they told me they got this plant from Yamaka Engei. And then I emailed Yamaka Engei with the picture of the flowers. And they would tell me "Yes, we likely sold that plant and that is a Koun" (preferibly without bringing up Koun yourself, making them arrive at it independently). Then it would feel correct for me to sell cuttings of that plant as Koun.
Maybe customers complaining or specifically asking for cultivar IDs will make the EU sellers more careful with the cultivar IDs.
I once offered a business to ID all their handwritten tags because they were selling theirs unIDed, but the picture showed the kanji tags were still on.
There are other Japanese imports that have tags in English and including a picture. Of course, that is much better for the EU market.
. I’ve got my eye out looking for a nice Chihiro although possibly not this year.
