<p>In mid-May 2020, a coccolithophore bloom of <i>Gephyrocapsa oceanica</i> Kamptner, 1943 was observed in Sagami Bay, Japan, possibly for the first time in 25 years. This species is a common yet elusive taxon in the waters around Japan, but there has only been one report of a bloom observation in Sagami Bay in 1995. The <i>G. oceanica</i> bloom in 2020 was observed by the combined approach of the JAXA ocean color remote sensing satellite “<i>Shikisai</i>” and field surveys. The true-color RGB images from the satellite showed the initial bloom in Tokyo Bay appears to have advected into Sagami Bay on May 5. On May 15, <i>ad hoc</i> field sampling was conducted based on visual confirmation from the shore. Nitrate, nitrite and phosphate concentrations at the sea surface were 3.28 µM, 0.11 µM and 0.29 µM, respectively, and higher than the median of May from 1997 to 2019. Chlorophyll <i>a</i> concentration was 2.23 µg L<sup>−1</sup> at the sea surface, and cell density was 5.3 × 10<sup>3</sup> cells mL<sup>−1</sup>. The large bloom appears to have reached the western shorelines of the bay, and dispersed counterclockwise within the bay. The bloom reached an estimated 1119.02 km<sup>2</sup> surface expression on May 17, and completely disappeared by May 24. Further, the median value of 19′-hexanoyloxyfucoxanthin (a signature pigment of haptophytes, including coccolithophores) concentration has been increasing from 2017 to 2020, and the coastal area of Sagami Bay may have changed to a region favorable for haptophytes.</p>
