Kishida sent the ritual offering of a masakaki tree on Tuesday under his name as prime minister on the occasion of the shrine's autumn festival. Earlier in the day, a group of Japanese lawmakers paid respect to the war-linked shrine. Japanese media reported that Yoshitaka Shindo, the minister in charge of economic revitalization, and Sanae Takaichi, the economic security minister, visited the shrine Tuesday morning.
