Japan is a very big market for luxury goods, so H will sometimes issue a cw or a special edition only for the Japanese market. Just last year, they released a special cw, very limited edition of Duo Cosmique for the Omotesando boutique and the price went through the roof in the resale market

IIRC, one of the scarfies here had the good fortune to nab one of these rarities. Well, one of my more quirky scarf acquisition preferences is to buy scarves made for the Japanese market if I find them at a reasonable price (so, NOT Duo Cosmique
unless I win the lottery).
The H boutique at Ginza has a couple of special editions associated with it. I have De Passage a Tokyo with its fascinating sketch of the city and a twilly of another design Ginza 5-4-1.

Ginza 5-4-1 is in a delightful pink which pairs well with my Alphabet and Red Berries twillies.

There is also Ginza 2001 scarf which Carre de Paris describes as issued for the opening of the building which houses H Tokyo HQ. A gav which shows the central motif of the Ginza 2001 90cm was printed as a silken invitation. The same gav without the words of the invitation is also available. Ginza 2001 is one of my grails.

Carreve was a gift to VIP customers in Japan a couple of years back. For the rest of the world, H released an embroidered version. This is a fave because the swirling motif is a quotation from Shakespeare's A Midsummer Night's Dream.

Ex Libris en Kimono, Matsuzakaya edition. According to H lore, the inspiration for ExLeK came from kimono fabric in the Matsuzakaya archive collex. Matsuzakaya started off selling silk kimonos and is now a large department store selling a wide variety of goods. I hesitated to buy this as it seemed awfully bright, but it's actually very wearable.

And this is my favourite amongst the Japanese scarves: Romantique for Japanese department store Takashimaya. Strictly for sentimental reasons. The cw is very pale. I prefer strong colours.
BUT 
my home H is in the Singapore branch of Takashimaya, so I will never part with this scarf
