1. Summary
URSI Commission E (Electromagnetic Noise and Interference) in Japan has been holding
technical meetings and sub-committee activities in collaboration with the Technical Committee
on Electromagnetic Compatibility (EMCJ) of the Institute of Electronics, Information andCommunication Engineers (IEICE), the Technical Committee on Electromagnetic Compatibilityof the Institute of Electrical Engineers of Japan (IEEJ-EMC), IEEE EMC Society Japan Joint
Chapter and Sendai Chapter, Society of Atmospheric Electricity Japan and some related
technical groups. The workshops, conferences, and meetings at domestic and international levelfor this term are summarized as follows.
Domestic academic activities of EMCJ and IEEJ-EMC:
1. Regular EMCJ Meetings
The EMCJ of IEICE had 10 regular technical meetings in the period of September 2020 toJuly 2021, and 17 regular technical meetings in the period of July 2021 to May 2021. These
regular meetings were technically co-sponsored by IEEE EMC Society Japan Joint Chapter andIEEE EMC Society Sendai Chapter. Three of them were co-organized with TechnicalCommittee on Electromagnetic Compatibility of the Institute of Electrical Engineers of Japan(IEEJ-EMC). In total 247 regular technical reports including 6 invited talks were presented.
The featuring technical topic of the July meeting was “Wireless power transfer technology andElectronic device implementation” and “EM Simulation, EMC and Microwaves” co-organizedwith the Technical Committee on Wireless Power Transfer (WPT of IEICE) and ElectroMechanical Devices (EMD of IEICE), and with the addition of the Technical committee on
Photonics-applied Electromagnetic Measurement (PEM of IEICE) in 2022 and 2021. Octobermeeting was focused on “EM Simulation, EMC and Microwaves” co-organized with theTechnical Committee on Microwaves (MW of IEICE) and Electronics Simulation Technology(EST of IEICE). The March meeting was co-organized by the Technical Committee onHealthcare and Medical Information Communication Technology (MICT) of IEICE.
Also in July, the meeting was held as the annual “EMCJ Young Researchers' Presentation
Meeting” which is co-sponsored by the Japan Institute of Electronics Packaging (JIEP)Electromagnetic Technology Committee.
2. Regular IEEJ-EMC Meetings
IEEJ-EMC held 3 technical meetings in the period of September 2020 to July 2021 and 7
technical meetings from July 2021 to May 2023. Two of them were sponsored by this technicalcommittee, and five were technically co-sponsored by the IEICE-EMCJ and IEEE EMC SocietyCommission E

Japan Joint and Sendai Chapters. During this period, due to the influence of the COVID-19, it
was held online or as a hybrid of onsite and online. A total of 19 technical reports werepresented by IEEJ-EMC at 10 meetings.
3. Activity of sub-committees of IEEJ-EMC
As of May 2023, there are three continuing sub-committees and one new sub-committee
under the IEEJ-EMC Technical Committee as follows. These are (1) Investigation committee onthe health risk analysis of electromagnetic field (July 2014 – June 2016 / June 2016 – May
2020 (Phase 2) / July 2021 – June 2024 (Phase 3)), (2) Investigation committee on
Measurement and evaluation technology for EMC elucidation of ESD phenomena (Oct. 2020 –Sept. 2023), and (3) Investigation committee on trend survey of advanced electromagnetic field
exposure evaluation basic technology (July 2021 – June 2024). And a new investigationcommittee was established which is (4) Investigation committee on energy management
systems towards carbon neutrality (April 2023 – March 2026).

Domestic academic activities in the field of natural electromagnetic noise:Commission E members in Japan working actively in the field of natural electromagnetic
noise are presented their research results in the following meetings and/or symposiums.
1. International conference/workshop(1) 34th URSI General Assembly (URSI GASS) 2021
The URSI GASS in Rome was originally scheduled for the week 29 August – 5 September,
2020. Due to the Covid-19 pandemic, it has been officially delayed to 28 August – 4 September,
2021 with hybrid format for the conference, allowing mutual interaction of in-presence and online participants. Several URSI-E committee members played session conveners and presents
papers in the field of atmospheric electricity and seismo-electromagnetics.
(2) 17th International Conference on Atmospheric Electricity (ICAE)This international conference is held every 4 years to promote the scientific research,stimulate discussions, presentation, and publication of scientific findings, as well as to enhance
education and raise public awareness regarding electrical phenomena in the atmosphere. The
17th conference was held face-to-face in Tel Aviv, Israel during 19 - 24 June, 2022. 58 oral and59 poster presentations were There were 58 oral and 59 poster presentations, and lively
discussions took place. Several URSI-E committee members presented papers in the field of
atmospheric electricity.
(3) American Geophysical Union (AGU) Fall Meeting 2020, 2021 and 2022
This international conference is held every December in USA and the most influential eventin the world dedicated to the advancement of Earth and space sciences. In 2020, the meeting
was held on line due to COVID 19 spreading from 1 to 17 December. About 25400 scientists
from 107 countries including US, Canada, UK, Japan, China, etc. attended and about 12000
posters are presented with 1.1 million views on line. Also, the meetings were held in a hybrid
Commission Emodel, aiming to capitalize on both in-person and virtual participation, in New Orleans on 1317 December, 2021 and in Chicago on 12-16 December, 2022. More than 20,000 scientificpresentations were delivered, with over 25,000 attendees from more than 100 countries,including the US, Canada, UK, Japan, China, and others. Several URSI-E committee memberspresented papers in the field of atmospheric electricity and seismo-electromagnetics.
(4) 3rd URSI Atlantic / Asia-Pacific Radio Science Meeting (URSI AT-AP-RASC 2022)
Due to the COVID-19 pandemic, the 3rd URSI AT-RASC was moved from 2021 to 2022 andURSI AP-RASC couldn’t be held in Australia as planned due to the travel restrictions. So thecombined 2022 AT-AP-RASC event, hosted in Gran Canaria, was offered a hybrid format.
Several URSI-E committee members presented papers in the field of atmospheric electricity andseismo-electromagnetics.
2. Domestic conference/workshop(1) 2022 URSI-Japan Radio Science Meeting (URSI-JRSM 2022)

and a particular emphasis is placed on enhancing the visibility of URSI in the Asian countries
and encouraging young scientists to contribute to various URSI activities. The URSI-JRSM
2022 was the fourth URSI-JRSM on 1 – 2 September, 2022. It consisted of Keynote Lecturesand Invited Talks by outstanding scientists, Oral Sessions and a Poster Session for contributedpapers. The topics of the meeting cover all the 10 URSI Commissions.

7 – 8 January, 2022, and in Tokyo on 6-7 January, 2023, with 41 and 33 scientific papers
presented, respectively. 5 commemorative lectures celebrating the 100th anniversary were alsodelivered in the 101th meeting. Several URSI-E committee members were presented the papers
related to the areas covered by Commission E.
(3) Japan Geoscience Union Meeting (JpGU) 2021, 2022 and 2023

and online in 2021, on 22 – 27 May, 2022, on 21 – 26 May, 2023. Online Poster Session werealso conducted on 29 May – 3 June, 2022 and during the same period as mentioned above in2023. JpGU is a large organization consisting of 51 academic councils related to earth andplanetary sciences with approximately 10,000 members. Prior to the pandemic, about 8,000
scientists participated in this event. The meeting has adopted a hybrid format since 2022,
Commission Eallowing attendees to engage both in-person and online without reducing the number ofparticipants and presenters. Several URSI-E committee members presented papers related to theareas covered by Commission E.
