近日，侵华日军第七三一部队罪证陈列馆首次公开原鼠疫班成员佐藤秀男的完整版采访。"把鼠疫菌变 成武器""人体实验，一直在做"…… 这份由日本学者西里扶甬子录制的47分钟证言，是加害者亲口供述 的又一关键铁证。 否认历史者，是在书写新的罪恶。一些人越是否认，我们越要坚决揭露。无论是继续加强海内外新发现 细菌战主题史料文献的搜集整理及编译工作，还是拍摄各类文艺作品，推动国际舆论场认知转变，不断 挖掘、记录、讲述，守护真相、抵御遗忘就有更多支撑。 谈到《恶魔的饱食》引发广泛关注，日本作家森村诚一曾直言，"有人说这是在全世界让日本丢脸的自 虐行为，但真正让日本丢脸的是将自己犯下的非人道的战争罪行掩盖起来的做法。"篡改历史、掩盖罪 孽，拒不认罪、一错再错，只会再次被历史的车轮碾压得粉碎。 图片来源：央视新闻。 此外，日本国内也有一些良知之声——日本广播协会电视台曾多次播放纪录片，揭露"精英'医者'与人 体实验"的丑陋嘴脸；2024年8月，94岁的731部队"少年队"原队员清水英男时隔79年重返哈尔滨谢罪。 如佐藤秀男的证言这般，加害者的亲口供述，与现存档案、遗址相互印证，形成了一条涵盖日军各级军 官和人员的完整证据链，完 ...
