I am very glad to hear of this news as I have both Turkish friends and Armenian friends. (To be precise, I have never been to Armenia and those I know belong to Armenian minority in Iran and Turkey.) Due to expansion and shrinkage of a nation in the history, the neighbouring countries have always experienced friction and kept bitter memory each other and we, Japanese, have also similar political and histrical issues with Chinese, Korean and other Asian people.
It is reported to take some more time for both countires to complete the domestic procedures, but I hope there will not be any longer much obstacle for nomalization of the relationship. It is not possible to change the history, but we can change today and tomorrow for better.
