SARS-CoV-2 RNA was discovered on surfaces inside cabins in the ship after 17 days of quarantine measures according to an NIID[0] staff member. It is not yet confirmed that this has been a vector for further transmission. During the vessel's quarantine in Japan, all passengers were quarantined on land, but some crew were quarantined on the ship. This quote appears roughly halfway down the page: "SARS-CoV-2 RNA was identified on a variety of surfaces in cabins of both symptomatic and asymptomatic infected passengers up to 17 days after cabins were vacated on the Diamond Princess but before disinfection procedures had been conducted (Takuya Yamagishi, National Institute of Infectious Diseases, personal communication, 2020). Although these data cannot be used to determine whether transmission occurred from contaminated surfaces, further study of fomite transmission of SARS-CoV-2 aboard cruise ships is warranted." And this quote earlier in the page refers to the quarantine in Japan: "After disembarkation of all passengers, crew members either completed a 14-day ship-based quarantine, were repatriated to and managed in their home country, or completed a 14-day land-based quarantine in Japan."
