The Japanese Army’s numeric kana cipher

Ōyama Iwao
fromŌyama Iwao
Terauchi Masatake
toTerauchi Masatake

Imperial Japanese Army telegrams of 1902–04 in which two digits stand for one kana on a fixed table; Harumi-Matsuba rebuilt the table from a filed translation and decoded four telegrams, checked here. Three give sentences, one of them through its filed contemporary translation; the fourth enciphers only a twelve-kana noun phrase, confirmed by its draft (61 of 73 pairs in telegrams that give sentences).

The telegrams
Four domestic Army telegrams: Chief of the General Staff Ōyama in Osaka to Lieutenant-General Terauchi and to Major-General Fukushima (March 1902); the 12th Division at Kokura to the General Staff, and division commander Inoue, also from Kokura, to the War Minister (January 1904).
Where
National Institute for Defense Studies, via JACAR: C09122911500, C09122909900 (General Staff telegram file, 1902), C09123116600 (General Staff, 1904), C03020059400 (Army Ministry 満密大日記, January 1904).
The cipher
A coordinate table: the first digit is the vowel row of the syllabary, the second the consonant column counted backwards; 10 is ン.
How it was solved
The table was inferred from one telegram’s twelve pairs against the readings pencilled on its outgoing draft, then tested on telegrams found later, one of them with no translation at all.
Credit
Harumi-Matsuba, with Claude, Codex and Sonnet (issue #58, kagigo1901-public, October 2026).
What it says
“Until I return to Tokyo, please handle the business of the General Staff as you see fit”; “please lend the required maps of Korea”, six days before the Russo-Japanese War began.
Still open
C09122909900 enciphers a noun phrase, not prose. In C03020059400 two of the twelve pairs are one digit off the table, and three characters of its filed translation are illegible. Three pairs that are one digit off the translations, probably slips by the writer; a 1901 telegram in another method; which Army cipher this table belongs to. No person has checked the transcriptions.

01 The table

Each kana is two digits. The first gives the vowel, the second the consonant:

ア 9カ 8サ 7タ 6ナ 5ハ 4マ 3ヤ 2ラ 1ワ 0
a 0ア 09カ 08サ 07タ 06ナ 05ハ 04マ 03ヤ 02ラ 01ワ 00
i 1イ 19キ 18シ 17チ 16ニ 15ヒ 14ミ 13リ 11
u 2ウ 29ク 28ス 27ツ 26ヌ 25フ 24ム 23ユ 22ル 21
e 3エ 39ケ 38セ 37テ 36ネ 35ヘ 34メ 33レ 31ヱ 30
o 4オ 49コ 48ソ 47ト 46ノ 45ホ 44モ 43ヨ 42ロ 41ヲ 40

A voiced kana adds 5 to the first digit and takes the column of its voiced row: ガ 9, ザ 8, ダ 7, バ 6, so ガ = 59, ジ = 68, デ = 37 + 50 = 87, ブ = 76. ン is 10, and a final 80 closes the message. The consonant columns run backwards through the syllabary, from ア at 9 to ワ at 0. The Army’s coordinate ciphers of 1874 and 1894 described on Cryptiana use iroha order instead. The same table is used unchanged from Osaka in March 1902 to Kokura and Moji in January 1904. It may be the Army’s 鑰号 (Yakugō, in use 1901–04) written without its key, or the numeric part of 特号; nothing found so far settles which.

02 The four telegrams

Army telegraph form of 27 March 1902 from Osaka, with seven columns of kanji numerals separated by black marks
Osaka, 27 March 1902, no. 987, 72 characters: Ōyama to Terauchi, all in digits. Read in columns from the right, top to bottom; the rightmost is 四四一〇一七四二二八 = ホンシヨク, and the leftmost holds only 八〇, the end mark.

C0912311660025 Jan 1904, Kokura → Iguchi, General Staff13ヨヨウノカンコクチズダイヨ + clear サレタシno translation; the reply draft sends maps
C0912290990028 Mar 1902, Osaka: Ōyama → Fukushima12カシグンエンシウケンガク11/12 with the draft’s furigana
C0302005940018 Jan 1904, Kokura: Inoue → War Minister12シンテイハクゼウシレイブ12/12 with the filed translation (pair 5 04, as Tomokiyo reads the image; ゼウ for 場)

C09122911500 is the whole telegram: 本職帰京迄本部ノ事務ハ貴官宜シク取計ハレタシ, “until I return to Tokyo, please handle the business of the General Staff as you see fit”. C09122909900, sent the next day, enciphers only カイグンエンシウケンガク, the observation of the naval exercise, inside a clear message granting permission. C03020059400 enciphers only the unit name, 辛碇泊場司令部 (Anchorage Command Shin), with 場 spelt ジウ; the rest of the telegram is in clear kana. On 23 October 2026 the JACAR item turned out to hold the filed contemporary translation (訳文) of the whole telegram on frame 0118: 辛碇泊場司令部ニ要スル下士以下及器具材料ハ門司補給廠支廠長ニ交付済。[…]ノ結了ハ支廠長ヨリ直接報告ノ筈。, “The NCOs and men and the equipment and materials needed by Anchorage Command Shin have been handed over to the head of the Moji branch supply depot. The completion of […] is to be reported directly by the head of the branch depot.” Ten of the twelve pairs agree with it; the telegram is deciphered with the translation carrying the two off-table pairs.

Army telegraph form from Kokura, January 1904: clear katakana and kanji numerals in four columns
Kokura, 25 January 1904, no. 62. The right column begins in clear, コロクニシ, then the digits 四二四二二; the left column ends in clear, サレタシ ヲハラ. Image: National Institute for Defense Studies, 参謀本部 雑 秘 明治37年 臨号書類綴, frame 0026, via JACAR Ref. C09123116600.

C09123116600 has no translation and is the real test of the table. Its thirteen pairs read ヨヨウノカンコクチズダイヨ, 要用ノ韓国地図貸与, and with the clear サレタシ that follows, “please lend the required maps of Korea”. The reply drafted in Tokyo two days later, in the same file, sends fifty copies of the 1:50,000 map of Korea and twenty of the 1:1,000,000 map of Korea and Manchuria. Two spellings are off: ヨヨウ for ヨウヨウ and ダイヨ for タイヨ. The contributor takes them as the sender’s. The telegram is from 25 January 1904; Japan broke off relations with Russia on 6 February.

03 How the table was found

Harumi-Matsuba’s search began with two telegrams in the General Staff’s 1901–02 files that mix clear kana with runs of digits. The outgoing draft of C09122909900 has furigana on the words that were to be enciphered, カイグン and エンシウ. Against them the twelve pairs show the pattern: ン is 10 three times; the first digit, modulo 5, follows the vowel; it reaches 5 or more only for voiced kana; and ア, カ, サ are 9, 8, 7. The rest of the table follows from that rule. Two telegrams found afterwards then read with it, C09122911500 against its translation and C09123116600 against its reply.

The 35 of 35 is not a wholly independent test. The table’s shape was completed with C09122911500 in view, and the バ column, 6, was fixed from its ブ = 76. The independent test is the Kokura telegram, which was found by searching the catalogue for runs of digits and has only thirteen pairs. A permutation control supports the table: with its row and column digits shuffled, 1,000 tables never come near the real agreement.

A fifth telegram, Hiroshima, 18 February 1901 (C09122806100), has fifteen pairs that this table does not read: the same ニ is written 91 and 69. It uses another method and is not part of this entry. The contributor tried the 1902 table with periodic additives and other rules, and nothing fits.

Not included: C09122806100 (18 Feb 1901, Hiroshima, Manabe → Tamura), 15 pairs in four runs that the 1902 table does
not read (the same ニ is 91 and 69). A different method, so by the one-key rule it is not part of this target; the
contributor's OPEN.md lists what was tried. Unread.

# C03020059400, frames 0118-0119: Division commander Inoue to the War Minister, January 1904: reading

Rests on: the telegram form (frame 0119, received 18 Jan [1904], from Kokura; JACAR PDF of the item, fetched 23 Oct 2026
through the viewer's `raw/` path) and the **contemporary translation** filed with it (frame 0118, 訳文, stamped 満密受第
八二號, "大臣宛 井上師団長"). The enciphered run is the twelve digit pairs at the head of the message (`../ct_C03020059400.txt`,
re-read on frame 0119: columns 1-3 "一七一〇三六一九〇?" "二八八八二九一七三一" "一九七六", then kana in clear); the rest of the
telegram is clear kana, carried here by the translation. Cipher run under the 1902 table: シ ン テ イ ハ ク ゼ ウ シ レ イ ブ,
the translation's 辛碇泊場司令部 at 12 of 12 pairs: pair 5 is 04 (ハ), as Tomokiyo reads the glyph after 〇 (24 Oct 2026; read
九, ア, here before), and pair 7, written 八八 (ゼ), gives ゼウ, a kana spelling of 場 (Harumi-Matsuba, issue #97). `[…]` =
illegible in the translation.

## Reading

辛碇泊場司令部ニ要スル下士以下及器具材料ハ門司補給廠支廠長ニ交付済。[…]ノ結了ハ支廠長ヨリ直接報告ノ筈。

## Notes

- The cipher covers only the unit name 辛碇泊場司令部 ("Anchorage Command Shin", the eighth of the anchorage commands
  designated by the ten stems); everything after it is clear in the telegram.
- Pair 5: the glyph after 〇 at the foot of column 1 is unlike the 九 two rows above it; Tomokiyo reads it 四 (04 = ハ),
  which the translation's 泊 needs. Pair 7: both digits are 八 (ゼ); ゼウ is taken as a kana spelling of 場 rather than a
  slip for ジ (68).
- `[…]`: three cramped characters after the ○ (前 and two more: 隊/陽, 半/準?); "前項" or "前隊" is possible, not
  settled.
- Read from the translation, not from the kana of the form: the clear kana are cursive and were not transcribed here.
