First of all, the eyes of many Japanese male stars are obviously horizontal double eyelids (of course, some are naturally processed the day after tomorrow). For example, J stands for Ikuta Touma, the original department stands for Gackt, and the actor stands for Kazuki Kitamura ... Many Korean men's eyes are single eyelids or inner double eyelids, and the corners of their eyes are slightly raised, such as LEE JOON GI ... Although it is not absolute, it is the mainstream. ...
Secondly, the key is eyebrows ... Korean male stars will not trim their eyebrows very thin or even not, while many Japanese men will trim their eyebrows very thin and obviously, so it seems that Korean male eyebrows will be more natural, while Japanese male stars' eyebrows are more visually impactful and exciting ... For example, Kamenashi Kazuya, the representative of J family, Hide, the representative of visual department, and Manabu Dawei, the representative of actors ... It can even be clearly found that many of them are not from the art world. ...
Third, the nasolabial groove is more important ... Many Japanese male stars have deep nasolabial grooves with well-defined and angular upper lips, such as Go Morita, the representative of the J family, Yoshiki Hayashi, the representative of the visual department, and Hideaki Ito, the representative of the actors. ...
Therefore, the outer double eyelids+obvious eyebrows+deep nasolabial groove of Japanese male stars ... put together, these elements will definitely look very impactful ... that is, they will be more enchanting. ...
The above is just my own opinion.
