Noël van 't End won gold in the category up to 90 kilograms at the Masters in Doha on Wednesday.
The reigning world champion settled in the final with the Georgian Beka Gviniashvili.
After just under two minutes, Van 't End placed a waza-ari and in the final phase he took the match with ippon.
In the first rounds, Van 't End had already dealt with Piotr Kuczera from Poland, Altanbagana Gantulga from Mongolia and the Russian Mikhail Igolnikov.
It is the first time that Van 't End takes gold at the Masters, where he only finished on the podium once before.
De Houtenaar won bronze in the prestigious tournament in Morocco in 2015.
In August 2019, Van 't End wrote history by being the first Dutchman since 2009 to conquer the world title.
At his last two performances - Grand Slam in Hungary and European Championship in Prague - he failed to finish on the podium.
The Netherlands can get even more medals on Wednesday, because with Marhinde Verkerk, Guusje Steenhuis (<78 kilograms), Simeon Catharina (<100 kilograms) and Henk Grol (+100 kilograms), four Dutchmen will compete for the bronze.
The World Masters started on Monday and will last until Wednesday.
On the first two match days, the Netherlands took silver twice (Kim Polling and Frank de Wit) and bronze twice (Tornike Tsjakadoea and Sanne Vermeer).
