With the little information you provided I was really confused but it really seems that you are looking for a soft blanket with a hibiscus pattern from China (examples come up when you search in Chinese for: 香水芙蓉毛毯). Does it have to be such a pattern? Can't you find similar blankets in your city? Anyway, your question is not related to Japan.
The tag (label) in your uploaded picture is not the main tag which includes manufacturer information. Look on the back side of that tag, or look elsewhere on the blanket for a tag with more detailed information. That should help you to identify the manufacturer of the blanket.
