They are often the source for lots of Asian ingredients in mainland Europe, while I was in the UK we sourced lots of things like umeboshi and miso from Holland; to my surprise being from CA with lots of access to Japanese/Chinese/Korean ingredients I found lots of the Dutch stuff to be really good.
I'm not sure if that has to do their with relationship (and desire for it's food) with Japan during the isolation period, but there were lots of Japanese products in a biodyanmic farm/shop I worked at in Germany too.
Sadly, it was rather limited in scope because they are the main exporters of conventional food in the EU for a reason.
After a few years living in the NL I was travelling home via London. I'd come to love vegan food while living here and expected London would be beyond my wildest dreams for choices, being so big and so diverse.
Imagine my dissappointment when I went to the shop and the closest thing to a vegan option I could find was a cheese and egg sandwich!
Ended op going to Boots where I found mint and sweetpeas.
