These Ikebana vases are Yamasan from Japan

Forgive me if this is posted elsewhere but I can't find it on the site.  These stylish and interesting ikebana vases are made in Japan by Yamasan. I was once told by a dealer that they are NZ but I went HMMMMM.  If anyone has a photo of a vase and mark can they please post it. Mine is buried in my computer files. This first link shows the mark and a made in Japan sticker very clearly.

I have one of these vases and found this info a couple of years ago, though it's only on the Facebook New Zealand Pottery page at this stage.

I see people are still listing Yamasan pottery on Trade Me as Crown Lynn. Where do all these wild stories come from about being made for the Japanese market? Must be opportunistic dealers They are so clearly NOT Crown Lynn, or even close to the style. I found this link which is helpful, and also has a clear stamp and sticker. https://c20ceramics.net/2017/03/17/yamasan-japan-modernist-ikebana-vases/

Yes I saw that listing and it made me scratch my head.
I added the listing to the Q & A Crown Lynn Facebook page to try to get to the bottom of it.

It was only a couple of weeks ago that a lovely lady told us on the Temuka Facebook page that her Yamasan vase was made at Temuka Potteries for the Japanese market sometime around WW2 according to the biggest collector of pottery in New Zealand. Good Grief !!

So who is the biggest collector in NZ? Not our friend in Wellington, can't imagine he would say that, or be involved in these vases. Not sure about down south though.
