"text-embedding-3-small" Model is available in Japan?

I’m in Japan and going to use model “text-embedding-3-small” but get an error “'You are not allowed to sample from this model”, my account is Tire 1 and I recently made it a paid account. Also, I can not see this model in my playground.
anyone can help?
