Is it possible to obtain a tourist visa for china in one work day from Chinese embassy/consulate in Japan?

We (french and swiss citizens) are on a longer journey through asia and will go leave japan in a couple of days for russia and then china. we first wanted to apply for a china tourist visa in russia but it seems that it would be easier to do while still in japan. our question is whether there is the possibility to obtain a tourist visa for china in one work day? or within two short days like for ex. applying in the morning of july 27th at the embassy in tokyo and picking it up on july 28th in the morning, before leaving japan in the afternoon?
thank you in advance for your efforts.
best regards
