Tokyo’s measures follow the announcement of similar sanctions by the United States earlier this month.
Japan has announced sanctions against nine people and a company over their alleged ties to the Palestinian armed group Hamas.
Japan’s Foreign Ministry said on Tuesday the measures would freeze the assets of individuals and a company that helped finance Hamas, which controls the Gaza Strip.
The sanctions follow the announcement of similar measures by the United States earlier this month.
Tokyo has tried to walk a fine line in the war between Israel and Hamas as it tries to balance relations with the US, its closest ally, and ties with energy-supplying partners in the Middle East.
Japanese Prime Minister Kishida Fumio has condemned Hamas’ October 7 attacks on Israel and called for the immediate release of the group’s prisoners, while expressing concern over civilian deaths in Gaza and the deteriorating humanitarian situation in the enclave.
Israeli officials said Hamas’ surprise attack killed at least 1,405 people, mostly civilians. Israel’s bombardment of Gaza has killed at least 8,306 Palestinians, including more than 3,400 children, according to Gaza officials.
Last week, Japanese officials called on Israel to suspend its attack on Gaza to allow humanitarian aid to be delivered to the besieged enclave.
However, Tokyo abstained on Friday from voting on a United Nations resolution calling for an immediate humanitarian ceasefire.
Japanese Foreign Ministry Kamikawa Yoko said her country had abstained in part because the resolution failed to explicitly condemn Hamas, reflecting the stance of a number of countries including Australia and India.
The non-binding resolution, proposed by Jordan, was adopted overwhelmingly, with 120 votes in favor.
The US and Israel were among fourteen countries that voted against the resolution.
