In September 2021, 25 diaries, pocket notebooks and memos by [[Saburō Hyakutake]] (Emperor Hirohito's Grand Chamberlain from 1936 to 1944) deposited by his relatives to the library of the University of Tokyo's graduate schools for law and politics became available to the public.<ref name="Hyakutake-diary">{{cite news |last=Kitano |first=Ryuichi |date=6 December 2021 |title=Diary: Hirohito prepared for U.S. war before Pearl Harbor attack |url=https://www.asahi.com/ajw/articles/14496398 |work=The Asahi Shimbun |access-date=30 January 2022}}</ref>

Hyakutake's diary quotes some of Hirohito's ministers and advisers as being worried that the Emperor was getting ahead of them in terms of battle preparations.

Thus, Hyakutake quotes Tsuneo Matsudaira, the Imperial Household Minister, saying:

{{blockquote|"The Emperor appears to have been prepared for war in the face of the tense times." (13 October 1941)<ref name="Hyakutake-diary"/>}}

Likewise, Koichi Kido, Lord Keeper of the Privy Seal, is quoted as saying:

{{blockquote|"I occasionally have to try to stop him from going too far." (13 October 1941)<ref name="Hyakutake-diary"/>}}
{{blockquote|"The Emperor's resolve appears to be going too far." (20 November 1941)<ref name="Hyakutake-diary"/>}}
{{blockquote|"I requested the Emperor to say things to give the impression that Japan will exhaust all measures to pursue peace when the Foreign Minister is present." (20 November 1941)<ref name="Hyakutake-diary"/>}}

Seiichi Chadani, professor of modern Japanese history with Shigakukan University who has studied Hirohito's actions before and during the war said on the discovery of Hyakutake's diary:

{{blockquote|"The archives available so far, including his biography compiled by the Imperial Household Agency, contained no detailed descriptions that his aides expressed concerns about Hirohito leaning toward Japan's entry into the war."<ref name="Hyakutake-diary"/>}}
{{blockquote|"(Hyakutake's diary) is a significant record penned by one of the close aides to the Emperor documenting the process of how Japan's leaders led to the war."<ref name="Hyakutake-diary"/>}}
