Having just got back from the Nord Pas de Calais Mining Basin, I thought people may like to see the car we parked next to:

That is a car with a laminated peice of paper with a Japanese flag and the words "World Heritage Hunter" They actually had three signs on the car!
In case people can't see that so well here is a larger copy.

I was trying to work out if it is perhaps Tsunami of this parish. I left them a note and kept an eye out for them, but didn't see them in the museum.

Anyway it was just a nice coincidence and good to know we are not alone in this obsession.

Great! I want a sign like that too!

I'll ask Tsunami to look into it

I did mention this website in my note so they may come to you anyway.

That does mean they would have to understand both English and my handwriting though so chances could be slim, especially on the latter :)

I am wondering if this is a particular Japanese phrase for the "hobby" i.e "Hunter" - see
"As the majority of my blog readers are Japanese, I wonder, will you ..... My friend knows I am a huge 世界遺産 [World Heritage] hunter, so I got a ....."

There are other web sites from Japan using the same phrase e.g
https://pledgie.com/campaigns/21984

Well, Tsunami denies everything.

No, it's not him. He also thinks that the word World Heritage Hunter isn't used so much in Japan. WHS in itself is very popular, but most people's English is too poor to communicate on this website for example (although they may have visited hundreds of WHS).

I didn't mean that the word "Hunter" was used in its English form in Japan but that the Japanese might have called the business of collecting WHS "hunting" in Japanese seeing as how so many of them on the web (and on cars in France!) use the word and that it gets translated as such into English.

Out of interest what is the translation of the equivalent word you use in Dutch (or German/Fr/Sp etc) to indicate what you/they "do"? I always say I "collect" WHS or "Collect visits to WHS" (or might perhaps say that "I Tick" or "I Tick off" WHS - but I wouldn't be a "WHS Ticker" let alone "WHS ticker offer"!). And I don't really think of the act of going around seeing them as one of "Hunting" (Except occasionally I suppose - e.g the Blaustien-Ehrenstein Pile dwelling location and the boundary of the WHS Forest at Kellerwald-Edersee!!).
If I were to put a notice on my rentacar (which I wouldn't and that perhaps says something!) it would say "WHS Collector". It just hits me that "World Heritage Hunter" is a slightly strange phrase and not really "English". The English are great "Collectors" and to me it seems more natural to use that word - though I could imagine US English adopting "hunting" and "Hunter"

Loves the logo of Sekaiisen Hanta

In Dutch it also is "collector" (verzamelaar), but sometimes I also use "hunt" (to go again on a hunt for world heritages).

Cute logo indeed!

This must be him/her?

P.S.: when I put the site through Google Translate, it looks like he "only" hunts photos of WHS (and not visit them himself)

I don't think it is. The dates don't seem to match up, and I think they are just finding photos rather than visiting each WHS. Also if I had designed that logo I would have included it on the paper on my World Heritage Hunter sign for the car, it would be too good to not use.
Though it did remind me I made my own sign for site visit number 200. Alas I forgot to print it out, so had to display it on a tablet screen, so the actual photos aren't that great.

Solivagant, did get me thinking about what term I use, and on reflection it seems I use a lot, but mostly the more cumbersome "I try to visit World Heritage Sites". I think I have used "World Heritage Site Collector" and even "Hunter". Though I quite regularly default to "World Heritage Site geek" or the more wordy "I have a Trainspotterish obsession with World Heritage Sites". I also quite like Iain Jackson's term bagging.

Aah! Not ashamed to be a WHS geek

Would be a great title for this website: "World Heritage Geeks"

It is my main character trait, so best not to be ashamed off it :)

Nice!
