Hi, I am a Dutch Citizen and I have a question concerning a Visa application in Japan

I am a Dutch (The Netherlands) Citizen who will be traveling to Japan on July 15th, to eventually travel to China on the 6th of August for vacation. I was wondering if I could apply for a Chinese L type one in Japan during my stay as I will not be able to apply for it in the Netherlands as I will be abroad from now till the 15th of july. Thank you
