PARIS — Hyper Cacher, the kosher supermarket here that was targeted in a terrorist attack in January that left four people dead and deeply shook France’s Jews, will open its doors on Sunday, senior Jewish officials said on Friday.

The supermarket has been closed since Jan. 9, when Amedy Coulibaly, a heavily armed Frenchman, lay siege to the supermarket in Porte de Vincennes in eastern Paris, holding hostage shoppers who had come to buy supplies for the Sabbath.

Four people were killed during the attack, including Yohan Cohen 22, who worked at the supermarket, and who French news reports said died while trying to disarm Mr. Coulibaly. The police eventually stormed the supermarket, killing Mr. Coulibaly, who had declared allegiance to the Islamic State.

Since the attack, the supermarket has become a potent emblem of a hate crime that spawned national soul-searching about anti-Semitism in France and the perils of Islamic extremism, while prompting some Jews to question their future in the country. Mourners have laid flowers in front, where portraits of the four victims remain. Police officers have patrolled outside the store, whose makeshift memorial has become a destination for residents and tourists.
