In my opinion we must be careful. What you ask is an interesting question, but at the same time, being specific, it deserves a more in-depth discussion. It would be wrong to say yes or no without arguing.
It is well established, from various studies of which I could also attach the results, that the Asians you mention often have a short foreskin. Short basically means that, when the penis is flaccid, the glans is not fully covered (i.e. all possible variables are included). This usually occurs during puberty. However, one should not believe that all Asians are like this. There are many Asians who have a "normal" or long foreskin. These researches show that Asians (again in reference to the countries you mentioned) have a foreskin that is on average shorter than other ethnic groups or that it is easier to find a boy with a foreskin that leaves the glans partially uncovered. Between a European or an African and an Asian, the foreskin of the Asian is more likely to be shorter.
Obviously, I want to write it again, we must not fall into extremes. If most Asians have this characteristic, it does not mean that it is necessarily predominant. To give an example, it could be said that the percentage of boys with a short foreskin among Europeans is around 20%, among Asians this figure increases to around 40%. Among other things, we often hear it said that Asians always keep their glans uncovered: the truth is instead that many of them have a short foreskin (which maybe every now and then tends to retract completely and stay in that position).
Last consideration hoping not to go too far off topic. This debate should make us reflect and possibly discuss about the importance of having the glans always covered once we have grown up, that is from adolescence onwards. Attention I am not talking about removal or uselessness of the foreskin, but I am referring only to the degree of glans coverage with flaccid and uncut penis. If naturally, with the development of the body, many men have a foreskin that leaves part of the glans exposed, is it therefore so fundamental that during adulthood it is always completely covered ? It would almost seem that, while this is essential until childhood, from puberty it is less important.
