The 4thKoriyama Sword City was held at the convention center “BigPalette Fukushima” in Koriyama City, Fukushima Prefecture. To help stop the spread of the coronavirus, we thoroughly measured the temperature of visitors, encouraged the disinfecting of hands, wore masks, and doubled the size of the venue to avoid crowded spaces. To be honest, I was worried about the number of visitors and sales. However, after the event I was happy by the fact that we were able to achieve record results and thus rewarding our hard work. I think the great turnout and sales were due to three factors, the local newspaper featured it in the article as a local event, the trust of the people of Fukushima Prefecture being this was our fourth event, and we were able to exhibit many local swords of Fukushima Prefecture. My staff and I are delighted that the last sales event of this 2020 was a success.
