PREFACE
Monograph No. 116, The Imperial Japanese Navy in World War H^ one of the Japanese Operational Monograph
Series covering operations of the Japanese Army and Navy during the period 1941-1945, is intended primarily as a
reference for research and analysis, specifically in connection with other volumes in the series, and does not pur
port to be complete in itself.
Initially prepared in Japanese by former officers of the Japanese IMavy under the supervision of the 2d
Demobilization Bureau (Navy), the material was translated into English by the Allied Translator and Interpreter
Service, General Headquarters, Far Eost Command, and edited for clar i ty, coherence, and accuracy by the Japa
nese Research Division, Military History Section, General Headquarters, Far East Command.
The chief sources used in compilation of this document included: Greater East Asia Imperial Japa
nese Navy Wartime Organi2ation, original and revisions, issued by the Chief of the Navy General Staff,
I June 1945; Battle Lessons, compiled by the Yokosuko Air Group; wartime diaries, battle reports, and Summa
ries of Merit of various units and ships, as submitted to the Navy Ministry and IMavy General Stoff; documents
ond reports of the Civil Merchant Marine Committee and individual ship owners; wartime documents and radio
messages available at the 2d Demobilization Bureau Liquidation Off ice; and interrogations, statements, and
private records of personnel concerned. In many instances material was either lacking altogether or consisted
of mere scraps, resulting in a certain amount of inaccuracy and incompleteness in some portions of the report.
The repori has been checked against all available Japanese sources, but has not been compared with documents
or material from other sources. To accomplish the latter would have involved a considerable amount of t ime,
delaying publication of the monograph s t i l l further.
The graphic presentation originally used in compiling the document in Japanese was carried over
into its translated form as the simplest and most accurate method of depicting the information.
That portion of Monograph 116 pertaining to Japonese shipping losses (Parts i n n and JK ) is not intended
as a duplication of information in Japanese Naval and Merchant Shipping Losses During World War U by All
Causes, p repa red by the Jo in t A r m y - N a v y Assessment Commi t tee and pub l i shed by the Un i ted S ta tes Depa r tmen t
of the Navy in February 1947. The l a t t e r vo lume l i s t s only those vessels of 5 0 0 or more g ross t o n s , w h i l e th is

PART I
ORGANIZATION OF THE FLEETS
NOTE
Part I is primarily concerned with the organizat ion of Fleets wi th numerical designat ions. The organizat ions of the First to Fourth Southern Expedit ionary Fleets inc lusive, which should be ca tego r i ca l l y l is ted in Part I , have been noted in Part III under the Southwest Area Fleet.
Ships and naval units which were under the direct command of the C - i n - G of the Combined Fleet were placed under the heading of Combined Fleet, as were the at tached units. The Combined Fleet, in its fu l l sense, actual ly encompassed all the Fleets l isted in Parts I , IT and M as wel l as the direct ly assigned and a t tached units.
The First Mobile Fleet, not graphical ly shown in any Part of this volume, was composed of the Second and Third Fleets and existed as such from I Mar to 15 Nov 4 4 ,
In the fol lowing char ts , the double horizontal lines represent the active tour of the naval units which comprised each Fleet and the single horizontal lines represent the breakdown of each naval unit. Changes in the organization ore noted as they occurred with dates in parenthesis.
