What is a sapporo sash?

It seems like you're asking about a "Sapporo sash," but there isn't any widely recognized item or garment with that specific name.

It's possible you're thinking of something else. Perhaps:

* A specific type of sash associated with the city of Sapporo, Japan: Could you provide more context about where you encountered this term or what you are looking for?

* A misspelling: Is it possible you meant a different word, like "Sari" or "Sash"?

Please provide more information so I can help you understand what you're looking for. 😊
