JAPANESE DEL;laNATION UNDERnATKR ORDNANCE
Introduction
1. The identifinetion of captured or recovered Japanese underwater ordnanceby means of markings and labels presents a difficult problem to person-nel unfamiliar with oriental language, for many obvious reasons, not theleast of which is the different alphabet employed. The fact that, as inthe English language, certain letters or combinations thereof often em-body several different meanings also adds to the problem as does thedifferent method of writing. This chapter purports to present backgroundInformation giving insight into the Japanese designation systems as wellas representative examples of labels found on or in captured or recoveredspecimens of underwater ordnance.
2. It should be noted that the Information contained herein ia intendedmerely as a guide, and the fact that it say serve to permit reasonablyeccurnte identification of some specimens should not be construed as re-lieving disposal personnel of the responsibility for making accuratetracings or clear photographs of all labels and markings encountered inthe line of disposal duties. The data presented herein, while believedto be accurate, are not couplets end therefor• not suitable as a basisfor • final decision as to ■ specimen's Japanese designation.
Understanding the Japanese ordnance designation system Is contingent up-on en understanding of the Japanese calendar system whereas proper read-ing and interpretation of markings and labels re4uire that tbs translatorbe familiar with the many ,agar les and inconsistencies of the Japanesenumeral system. Brief discussions of the calendar and numeral systemsfollow Immediately below.
Japanese Calendar
1. The Japanese employ two distinct calendar systems, one in which thecurrent year is reoorded with respect to the founding of the Japaneseempire, and the other in which the current year is recorded with respectto the date on which the reign of the incumbent emperor began. Theempire was founded in 740 B.C. hence the Christian year 19,5 is 200; inthe empire calendar. Three eras based on an emperor's reigning yearsare pertinent to this discussion:
(a) The Meiji Ere ( .01 ) 1868 to 30 July 1912.
(b) The Taisho Ere( 9- J,) 31 July 1912 to 25 December 1926.
(c) The Shows Era ( fo 4C7) 26 December 1926 to date.
The Christian year 1945 is therefore the year 20 of the Shows Er..
Numeral System
1. Although the Japanese characters representing the cardinal numbers arewell standardized, 1 systems are used for writing multiples andnumber combinations with resultant confusion in translation. The numbercombinations are usually set down, in Japanese Characters, either fromleft to right or from top Lo bottom, but In some may be foundwritten from right to left In the traditional oriental manner. It willbe noted, Do that long eeriest of numbers such ail serial numbersare almost always written in arable numerals In the conventional manner.
2. Two different systems employed for writing number combinations followbelow:(a) The arithmetic method whereby the actual addition and multiplica-tion involved In achieving the sum or multiple is depicted In the
characters representing said sum or multiple. This method hasrarely been encountered and la not believed to be in general use.Typical examples are given below:
(1) 15 ten.(plusl five(2) 50 five (times) ten
(3) 57 4 -tfive Itimes) ten (plus) seven
(4) 6231 )).Z -i- six (times) thousand (plus) two

1. The primary or basic designation of Japanese underwater orinance Is gen-erally the type number. This ordinarily consist, of toe last two num-bers of the empire calendar year, or year of the ere of the reigningemperor, during which the ordnance wee officially accepted for service.During the Meiji and Taisho eras, the era year sus generally used whileduring the present (Shown) era, the empire year hes been most often used.In the accompanying calendar (Fig. A ). the numbers used for ordnancedesignation for each year since 1900 are underlined. It will be notedthat the year designations used In the years 1912-191h and 1941-1945 areIdentical. The actual designations used, however, are easily differ♦entlated because, while the type numbers used are Identical, differentsystems are used to record the actual designations. For example, the
designation iNI(Third Year Type) Indicates that the ordnance
was adopted in 1914 at eeeee the designation 1: it (Type 5) Indicatesadoption in 194).
Yodel and Modification Number,
1. These numbers ere used to designate various degrees of change in basictypos (see Pers. 1 ebovs) although their exact Ognifloancs is not def-initely blown. All ordnance designation system. contain inconsistenciesmind the Japanese system is no szoeption. The following conclusions,drawn from examination of various sposisans, have been generally borneout and are believed to be reasonably ammonium...
(a) If a model number is assigned to an ordnance Item, it indicates thatchanges of an adaptive nature have been made. In the, ease of a mine,slight alterations in Its size or shape for the purpose of adaptingIt for laying from en unusual type of minelayer would probably mar-
' rant assigning a model number.
(b) If u modification number is assigned to an ordnance Item, it indi-cates that changes or a corrective or improving nature have beenmade. In the case of a mina, correction of a fault in the ninefiring mecneniem by a design change would-probably warrant assigninga modification number.
2. Model and Modification numbers oaf, be assigned In combination to a mingleordnance Item. Although the Japanese system for so assigning tease num-ber, is not definitely known, examination of captured specimens indicatesthe following to be generally applicable:
(a) Modifications of earlier Model. are ordinarily indicated In an item'scomplete designation. The hypothetical example of a mine designated,"Type 26, Model 3, Modification 1" Indicates that a Modification has
