Great Britain, at the conclusion of the 2021 World Judo championships, had achieved quota places in the following weight categories. Nekoda Smythe-Davis had qualified a continental quota place in the −57 kg category, but had already withdrawn from Olympic consideration for health reasons. On 5 July 2021, Team GB announced the judokas who will compete in Tokyo, including debutant Sarah Adlington in the women's heavyweight category, who had been awarded a continental quota following the official withdrawal of Smythe-Davis.Nations are restricted to one continental quota place across all weights. Adlington therefore became eligible for the continental quota upon the withdrawal of Smythe-Davis.
