Discussion & Questions

 
(MOGAMI in 1935 - colorized by Irotooko, Jr)

The Tabular Records of Movement (TROMs) presented on these pages for the Imperial Japanese Navy's "Junyokan" - cruisers - have been prepared by Bob Hackett and Sander Kingsepp from Japanese and American source materials. Japanese cruisers ranged throughout the Pacific in World War II and were in the forefront of virtually all the major engagements against Allied Forces.

As these TROMs disclose, only a few "Junyokan" meet their doom in the surface engagements for which they were designed; most were destroyed by bombs and torpedoes delivered by aircraft or had their hulls ripped open to the seas by submarine-launched torpedoes.

As usual, every effort has been made to provide the latest verified information on the movements, engagements and ultimate fates of these major combatants. Feel free to post any questions to us on the Discussion and Questions board links.
