COMMUNICATION FROM JAPAN  
Addendum  
The following communication, received on 27 September 2023 , is being circulated at the request of 
the delegation of Japan . 
 
_______________  
 
 
1.  In this communication, Japan would like to provide further updates  to document 
G/SPS/GEN/1233/Rev.6/Add.1 , dated 4 September 2023, as well as its counterargument in response 
to China 's communicati on in document G/SPS/GEN/2153 , dated 20 September 2023, and Hong Kong, 
China's  notification in document G/SPS/N/HKG/49 , dated 21 September 2023.  
2.  Firstly, Japan expresses its regret concerning China 's communication in document 
G/SPS/GEN/2153 , in which China repeats its previous position without taking any account of the 
scientific information  consistently provided by Japan, including Japan 's communication in document 
G/SPS/GEN/1233/Rev.6/Add.1 . Japan  also expresses its regret concerning Hong Kong, China's  
notification in document  G/SPS/N/HKG/49 , in which Hong Kong , China  notified an import prohibition 
of all aquatic products originating from 10 metropolis/prefectures in Japan, and urges Hong Kong , 
China  to immediately repeal its measures. Japan 's counterargument to China 's communication and 
Hong Kong, China's  notification has already been clearly stated in its previous communication in 
document G/SPS/GEN/1233/Rev.6/Add.1 . Japan does not intend to repeat it in this communication, 
but would like to provide the following supplemental information.  
3.  As explained in the communication in document  G/SPS/GEN/1233/Rev.6/Add.1 , since the 
discharge of the ALPS treated water started on 24 August 2023, th e Government of Japan and Tokyo 
Electric Power Company Holdings (TEPCO), with the continued involvement of the IAEA, have been 
conducting monitoring  of (i) the ALPS treated water in tanks before discharge, (ii) tritium concentration 
after dilution, water f low rate, and gamma radiation level immediately before discharge, and (iii) 
concentration of tritium and other radionuclides in sea water , seabed sediments and fishery products 
after discharge. The IAEA, with the participation of third country analytical i nstitutions, objectively 
confirms Japan 's analytical capabilities and the reliability of its data. Monitoring results have been and 
will continue to be made public. As clearly demonstrated by these results, the discharge is safe.  
4.  On 4 September 2023, Japa n requested discussions with China concerning its emergency measures 
based on paragraph 2 of Article 5.11 of the Regional Comprehensive Economic Partnership (RCEP) 
Agreement. On 15 September 2023, Japan made another request to China for discussions based o n 
Annex B .6(c) of the SPS Agreement. China has not yet responded to either request for discussions.  
5.  Japan remains committed to providing any further explanation required and to having science -
based discussions to dispel any concerns or misunderstandings with regard to the safety of the ALPS 
treated water discharge. Japan is also committed to providing as surance that there are no grounds 
for China and Hong Kong, China to maintain their measures. For the sake of a rules -based resolution, 
Japan repeats its requests to China to engage in the discussions requested by Japan in accordance 
with the international agreements binding both China and Japan, namely the RCEP Agreement and 
the SPS Agreement.
