This study aimed to clarify the number of *nage-waza* (throwing techniques) acknowledgements and objections from inside and outside the triangle made by the referees in the conventional referee positions using the International Judo Federation Refereeing Rules. The findings of the study are as follows.

1. *Nage-waza *acknowledgements were performed 200 times (47.4%) inside the triangle connecting the three referees with a straight line and 222 times (52.6%) outside the triangle, with no significant differences.

2. No objections (3-0) were made 168 times (47.6%) inside the triangle connecting the three referees with a straight line and 185 times (52.4%) outside the triangle, with no significant differences.

3. Objections (2-1, 1-2, 1-1-1) were made 32 times (46.4%) inside the triangle connecting the three referees with a straight line and 37 times (53.6%) outside the triangle, with no significant differences.

4. Objections (2-1) were performed 15 times (48.4%) inside the triangle connecting the three referees with a straight line and 16 times (51.6%) outside the triangle, with no significant differences.

5. Objections (1-2) were performed 16 times (44.4%) inside the triangle connecting the three referees with a straight line and 20 times (55.6%) outside the triangle, with no significant differences.

6. Objections (1-1-1) were made once (50%) inside the triangle connecting the three referees with a straight line and once (50%) outside the triangle, with no significant difference.

7. Inside the triangle connecting the three referees with a straight line, no objections (3-0) occurred 168 times (47.6%) and objections (2-1, 1-2, 1-1-1) occurred 32 times (46.4%). Outside the triangle connecting the three referees with a straight line, no objections (3-0) were made 185 times (52.4%) and objections (2-1, 1-2, 1-1-1) were used 37 times (53.6%). There were no significant differences in the percentages inside and outside the triangles, with and without objections.

The above suggested that with conventional referee positions, it was desirable for *nage-waza *acknowledgements to be conducted inside the triangle and for assistant referees to move. However, it could not be concluded that there was a problem in the number of objections. In the future, in situations where the assistant referees cannot present an acknowledgement of *nage-waza* to the referee, it will be necessary to compare the number of occurrences of objections between the inside and outside of the triangle in the conventional referee positions.
