<jats:title>Abstract</jats:title><jats:p>For the realization of a next‐generation energy society, further improvement in the activity of water‐splitting photocatalysts is essential. Platinum (Pt) is predicted to be the most effective cocatalyst for hydrogen evolution from water. However, when the number of active sites is increased by decreasing the particle size, the Pt cocatalyst is easily oxidized and thereby loses its activity. In this study, a method to load ultrafine, monodisperse, metallic Pt nanoclusters (NCs) on graphitic carbon nitride is developed, which is a promising visible‐light‐driven photocatalyst. In this photocatalyst, a part of the surface of the Pt NCs is protected by sulfur atoms, preventing oxidation. Consequently, the hydrogen‐evolution activity per loading weight of Pt cocatalyst is significantly improved, 53 times, compared with that of a Pt‐cocatalyst loaded photocatalyst by the conventional method. The developed method is also effective to enhance the overall water‐splitting activity of other advanced photocatalysts such as SrTiO<jats:sub>3</jats:sub> and BaLa<jats:sub>4</jats:sub>Ti<jats:sub>4</jats:sub>O<jats:sub>15</jats:sub>.</jats:p>
