Can I apply for a Chinese Z-Visa as a EU citizen visiting Tokyo?

Dear all,

I need to apply for a Z type soon and plan on going to Tokyo for a weekend trip. I am wondering if it is possible to apply for this kind in Tokyo, even though I am a tourist in Japan and only staying for a weekend?

Does anyone have experience with this and could help?

(all required documents are at hand)

Thank you!
Regards, Flo
