*To keep the shareholders who cannot attend the Meeting in person informed, video recording of part of the Meeting will be made available on our corporate website (https://www.nipponsanso- hd.co.jp/ir/stock/meeting.html) afterward (Japanese language version only). We are planning to post the video in late June, so interested shareholders are welcome to access the site.

A camera will be set up at the venue on the day of the meeting for the above-stated video recording. To respect the privacy of shareholders in attendance, the recording will be basically limited to the images around the chairperson's and officers' seats. However, if an image of an attending shareholder is captured for unavoidable reasons due to the venue, etc., the image will be processed to ensure that the individual cannot be identified. Q&A session part will be cut off form the video. Thank you for your understanding.
