大森和他的同事在舊金山市區內量測毀壞的建築物並拍照。他們還報告多次遭到當地人攻擊[18]。至少有兩人指出大森房吉和他的同事在舊金山米慎街(英语:Mission Street)遭到一群以丟石塊等方式隨機攻擊日本人,被當地媒體稱為反日種族主義者(英语:Anti-Japanese sentiment in the United States)的成年人和青少年攻擊[19][20];然而,同時期的消息來源指出因為美國的日本人組織抗議造成當地一位郵差被解雇時,大森房吉遭到當地一名男童丟石塊攻擊[21]。而寄到當地報紙的一封信中所提到的其他意外並沒有其餘的來源可以佐證[22]。大森房吉本人則選擇原諒,並且寫下:「關於我在舊金山因為一些流氓引發的麻煩。我個人相當高興看到,夏威夷居民不喜歡看到我被這樣對待。但我確實沒有受傷,並且沒有承受到任何惡意。在所有國家都有流氓,加州人對我非常好,而我對我的旅程感到非常快樂」[23]
