Many will wonder what Nitto corresponds to, the word that appears next to ATP Finals in the commercial name of what has traditionally been called the Masters or the Masters Tournament. Nitto Denko Corporation is a company based in Japan, the first in that country to sponsor this event, which it has been doing since 2017.

Founded in the Osaki district of Tokyo, the firm is now based in Osaka, as its headquarters were destroyed in the bombings that the Japanese capital suffered during World War II. It employs more than 30,000 people according to the latest data, from 2014, and in 2018 it celebrated its 100-year history.

Nitto is mainly dedicated to the chemical industry, although its products, more than 13,500 in all its areas, are aimed at a wide range of activities, such as electronics, transport or ecology. They manufacture from membranes for desalination to tools for the automotive industry and construction or bandages and surgical clothing. Its agreement with the ATP also includes the supply of a large quantity of its creations as the official supplier of the Finals.
