It is my great pleasure to host the 12th Asian Conference of Power Sources in Japan. This is the third ACEPS to be held in Japan. As an after-corona, we have decided to hold the conference only in person.

Recently, we have extensively suffered from abnormal weather conditions. To solve this problem and to fabricate carbon neutral society, our main targets, R&D of storage batteries, fuel cells, capacitors, and solar cells will be quite important.

We would like to discuss a lot of basic researches on these energy devices at this conference, and enhance our friendship at the reception. We sincerely look forward to your participation.
