Here is an interesting home service company that seems to be making a big push to the English speaking market as well as the Japanese one. They have a full line up of services ranging from walking your dog, doing your shopping, making your bed to dressing up for kids parties and entertaining you. In fact they boast that any service you want they can deliver.
English Language Site
The English language site is easy to follow and has a good fresh feel about it.
I have not tried out any services yet, but picked up a catalog at the station. If you are looking for a company to help you out this may be a good place to look.
