To put this into proper perspective I would like to see the numbers for people under the age of 25 and drivers who had their driving license for only 2 years or less.
I cannot speak for all of Japan, but only for Saitama where I live. Most prefectures have data for your question. Just need to know where to look.
In Saitama, (#3 in Japan....ouch) Over 56% of the deaths are from people over the age of 65. (These people do not have to be just driving, it also includes bicycles / mopeds / pedestrians) Source: https://www.police.pref.saitama.lg.jp/f0011/kotsu/documents/nippou_3.pdf ( Main page: https://www.police.pref.saitama.lg.jp/f0011/kotsu/kotutokei.html )
