Yuko's Shop (in xxxHolic) is the place where most of the storyline develops. This place also works as a residence to Yuko Ichihara. People residing the shop include: Yuko, Maru and Moro, Larg (Black Mokona) and Watanuki.
The shop located in Tokyo, modern day Japan (According to CLAMP's Universe, other mangas developed in the same world/time would be Suki. Dakara Suki, Lawful Drug, Kobato and possibly CardCaptor Sakura.)
The store offers to grant wishes in exchange for a payment equal in value to the wish, it is a kind of reference point through worlds, which traditional design contrasts with the modern architecture of the contemporary buildings of the XXI century. However, this residence can only be seen by those who need help or by spirits and monsters of all kinds, especially the bad ones, as the house is protected by a kekkai, ie a spiritual barrier, which keeps these spirits away. In the eyes of those who do not have a deep desire for something, they will only see an abandoned empty field among other buildings adjacent to the property. . The presence of Yūko at the shop takes on a ghostly touch since it can always be seen the smoke of incense lit (both in the manga and anime), as well as the smoke from her kiseru, thereby showing the personal touch of the witch to the place.
The house is a shop where it occurs - converge - the inevitable, which is the fact of entering at the most desperate moment in life to ask for a wish and give in return -this is one of the most attractive points of xxxHOLiC series- something of equal value. "Nothing more, nothing less" as the rule says, which in most cases turns out to be the most valuable thing a person possesses. The stories take on a tinge of psychological terror in the plot, usually with a final dialogue or monologue of Yūko about the theme of the chapter.
The objects found there are not strange to Yuko, who knows their origin and the person they are intended for, but never says so; she doesn't reveal her true intentions waiting for the inevitable to happen.
The shop's existence is connected both to the fates of the characters in xxxHolic and Tsubasa. As Tsubasa's story advances, Yūko and Mokona see that the shop's wards are weakening. In chapter 157(xxxHolic), the wards of the shop collapse, revealing the shop completely. It is most likely this event which makes it possible for Fei Wong Reed to attack Yūko in chapter 183 of Tsubasa RESERvoir CHRoNiCLE. In chapter 167 (xxxHolic) the shop itself dissolves, but the Storage Room is unaffected, which leaves Yuko a chance to continue her plan.
It should be noted that Yuko stated that this shop was especially created for one purpose; "for the day which has to come" which was later revealed in Tsubasa-RC- to be the day when the Clones would have to be revived, because Yuko paid Sakura's new life with all the items she kept in the Storage Room; while Syaoran's new life was paid with Clow Reed's magic. Also because this is the room where she kept the tube containing Sakura and Syaoran Li, who she releases in the final arc of Tsubasa -RC-.
When Yuko dies, Watanuki decides to take over as the Owner, until he meets Yuko again. At first, when Watanuki took on his new role, he had trouble finding out the balance for the wishes, thus, he was hurt in the process. However, 10 years later he seems to understand the rules involving granting wishes, and he is hurt no longer.
