View text of the letter

Quite a few historical records are on display in this exhibition. At first glance, some seem to have a "high threshold" of illegibility, having been written in the cursive style, or typically having been written, as with a letter, with only the recipient in mindnote. Still, such historical records can sometimes serve as valuable clues that are tucked inside the "crevasses" of history.

This corner of the exhibition uses the example of a naval officer's correspondence (letter), with a concrete explanation of the basic steps taken to decipher it as a historical document, with the aim of getting you to enjoy such materials more deeply.

Handling a piece of correspondence (letter) as a historical document - The Basics -

Who is the sender and who is the recipient?

The first step in using a letter as a historical document is to specify the sender, the recipient, and the date.
We determine from reading the end of the letter and the envelope that the sender was "YAMANASHI Katsunoshin" and the recipient was "SAITO Makoto."

SAITO Makoto among other positions, served as Governor General of Korea (1919-1927; 1929-1931), Prime Minister (1932-1934), and Lord Keeper of the Privy Seal (1935-1936).

YAMANASHI served as Vice Navy Minister, and had served commander-in-chief of the Sasebo and Kure Naval Bases.


When was it written?

At the end of the letter, only "May 1" has been written, without reference to the year, moreover the envelope lacked a postmark. That means we must search for additional clues, in the body od the letter. There two key words appeared: "Minister TAKARABE" and "disarmament."

Ever since the establishment of the Cabinet system, there has only been one Cabinet minister with the surname of TAKARABE: TAKARABE Takeshi. He served twice as Navy Minister, these two tenures happened to overlap with the London Naval Conference on disarmament, at which he served as one of the Ministers Plenipotentiary. The Conference took place in 1930 (Showa 5), we can surmise that this letter was written on 1 May, 1930 (Showa 5).

Just to be certain, let us check the positions that the people associated with this letter held while TAKARABE was Navy Minister.
