Prime Minister Fumio Kishida flew back to Japan on a chartered flight Thursday morning after visiting India, Ukraine and Poland.
After his return, Kishida met with members of the press at the Prime Minister's Office in Tokyo.
He said that it felt that it was important to support Ukraine. I renewed my conviction that we have to maintain the international order based on the rule of law. Kishida spoke about his visit to the suburban city of Bucha, where many civilians were massacred.
The prime minister said that the Russian invasion of Ukraine is an atrocity that undermines international order.
On Wednesday, the ruling coalition and opposition agreed to listen to Kishida's report on his visit to Ukraine during a plenary session of both the House of Councillors and the House of Representatives at the Diet. It will be discussed during Diet interpellations.
The interpellation at the lower house will take place on Friday and the upper house will take place on Monday. The parties also agreed to hear Kishida's report at the beginning of the upper house's Budget Committee meeting on Thursday.
