Eisuke Mori reaches Kyiv, the first Japanese lower-house speaker since the invasion

Eisuke Mori, speaker of Japan’s House of Representatives, arrived in Kyiv on 14 September. The lower-house secretariat confirmed the trip the same day. He is due to stay through 15 September and to meet Ukrainian government and parliamentary officials. It is the first visit to Ukraine by the head of a Japanese parliamentary chamber since Russia’s full-scale invasion in February 2022, and the first by a lower-house speaker in 15 years. Takahiro Yokomichi made that earlier trip in 2011.

Ruslan Stefanchuk, chairman of the Verkhovna Rada, said he had spoken with Mori in Paris a day earlier on the sidelines of a G7 meeting and then met him in Ukraine. “Just a day ago, we were speaking in Paris on the sidelines of the G7 Summit. Today, I am meeting Eisuke Mori here in Ukraine,” Stefanchuk wrote. He said the visit would let Mori see the effects of the war and hear Ukraine’s current needs, and that the two sides would discuss further support and new work between the parliaments.

Mori is one of Japan’s four top state officers, with the prime minister, the House of Councillors president and the chief justice. He has worked the Ukraine file for three decades. He was present at the 1995 launch of the cross-party Japan-Ukraine parliamentary friendship group and chaired it from 2011 until this year. As chair he visited in 2013, 2015 and 2019 and inspected the Chernobyl plant. Kyodo described him as one of the Japanese politicians most familiar with Ukraine. The last visit by a Japanese top state official was in 2023, when then Prime Minister Fumio Kishida met Volodymyr Zelenskyy and invited him to the Hiroshima G7.

Mori is expected to repeat Japan’s line against a change of borders by force and to talk about reconstruction. He also carries a nuclear brief. Japan’s own Fukushima accident in 2011 and Chernobyl in 1986 give him a technical subject that Ukrainian hosts still use. The trip comes as Trump claims an energy-strike pause that Kyiv treats as a proposal, and as a NATO jet has just shot down a drone over Lithuania. A speaker cannot move missiles. He can put the Japanese Diet on the record inside Ukraine rather than only in Paris.

The Ukrainian government said it is rare for a senior Japanese official to address the parliament. Whether Mori speaks in the chamber on 15 September will be the public test of how far the visit goes beyond closed meetings. The private test is whether any new reconstruction money or parliamentary working group is named before he flies home. Japan has already spent years on both. The speaker’s presence is meant to show that the file has not been parked while other wars take the headlines.

Mori leaves on Tuesday. Stefanchuk’s welcome is the official Ukrainian line. The Japanese line will be issued after the last meeting. Until then the fact that matters is the simpler one. The speaker of the lower house is in Kyiv, and no one in that job has been there since the invasion began.
