When EDQA was started,  the object was limited to beams  of reference  condition (10cm square  field size, 10cm depth in water) and was expanded  to non-reference  conditions of field size changes  and wedge filter insertions in 2010. In this study we report the results of this EDQA and the present  status of dose estimation in Japan evaluated  from EDQA.\nMethods: In the EDQA by ANTM, radiophotoluminescent glass dosimeter (RGD) is used as the detector. ANTM send RGD elements  and solid phantom  to radiotherapy  departments  and RGD are returned to ANTM after the irradiation of a specified dose. The dose delivered to RGD is measured  at Dose Calibration Center of ANTM and is compared to the dose stated by radiotherapy department.  \nResults: Until March 2016,  3,351  beams  of 784 therapy units from 629 departments  have been audited. The numbers of beams  are classified into 1,663 of reference  condition, 1,103 of field size change and 585 wedge filter insertion. The averages  of difference between measured  and stated  dose were 0.39% in reference condition, 0.19% in field changes and 0.17% in wedge filter insertions. The standard  deviations were around 1% for all conditions.  \nConclusions: The external dose QA by  ANTM shows that the status of dosimetry at radiotherapy departments  in Japan is in satisfying level.
