Aizawa High Pressure Concrete Co., Ltd. (Head office: Tomakomai City, Hokkaido; Representative Director: Aizawa Yoshihiro) will hold a commemorative lecture at the Sapporo Convention Center on Monday, October 27, 2025, to celebrate its 90th anniversary.
The lecturer will be Makoto Mogi, a popular author, cram school teacher, and history YouTuber, who will give a super history lecture titled "Hidakami, Emishi, and the Ezo Republic."
It has been 80 years since the end of the Greater East Asia War. As society once again undergoes major changes, I hope to use this as an opportunity to reflect once again on the path our country has taken and to awaken Japan to liberate itself from the shackles of postwar ideology.
