In a diplomatic reshuffle, the outspoken and charismatic Ukrainian ambassador to Japan, Sergiy Korsunsky, is set to be replaced.

Korsunsky played a key role in galvanizing Tokyo’s support for Kyiv amid Russia’s ongoing invasion. The announcement by President Volodymyr Zelenskyy on Saturday came a day after he approved over 30 other ambassadorial appointments. A successor has yet to be named.

The ambassador confirmed to The Japan Times that his four-year term had already been eclipsed, calling the reshuffle “nothing special.”
