Henk Grol reached the semifinals at the Masters in Doha on Wednesday.
The heavyweight saw Roy Meyer, his competitor for the only Olympic ticket, also be eliminated in the first round.
Guusje Steenhuis, Noël van 't End and Simeon Catharina joined the last four, just like Grol.
The 35-year-old Grol first dealt with the Hungarian Richard Sipocz and then also with Aliaksandr Vakhaviak from Belarus, whom he got into a hold.
The Groninger was too strong for the South Korean Minjong Kim for a place in the semi-finals.
Grol's performance is bad news for Meyer.
The 29-year-old judoka was eliminated in the first round by reigning Olympic champion and eight-time world champion Teddy Riner.
Jur Spijkers did reach the second round, but had to acknowledge his superior to the Brazilian David Moura.
The Dutch judo association recently designated the Masters as one of the three measurement moments for the distribution of the Olympic tickets, which makes it important to perform well in Doha.
The other two tournaments are the Grand Slam in Tel Aviv (February 19-21) and the European Championship (April 16-18).
Steenhuis to semi-finals, Verkerk to resits
In the category up to 78 kilograms, the battle for the Olympic ticket is between Steenhuis and Marhinde Verkerk.
Steenhuis did good business by reaching the semi-finals, while Verkerk will compete for bronze in the rematches.
World champion Noël van 't End (-90 kilograms) did not have to take action in the first round and was too strong for Piotr Kuczera in the second round.
For a place in the semi-finals, Van 't End settled in the final phase with Altanbagana Gantulga from Mongolia.
In the category up to 100 kilograms, there was also Dutch success, as Simeon Catharina joined the last four.
The Dutchman won his first three matches and awaits a showdown with Azerbaijan Zelym Kotsoiev for a place in the final.
The Masters started Monday and lasts through Wednesday.
The Netherlands took silver twice on the first two match days (Kim Polling and Frank de Wit) and bronze twice (Tornike Tsjakadoea and Sanne Vermeer).
