Could World War II have ended differently less catastrophically for Japan?

Did the Japanese Imperial Navy possess the technological potential to devise weapon systems capable of holding the United States Navy and Army Air force at arms length for an additional six months?

And could peace forces inside and outside of Japan's military and governmental agencies have used such additional time to gain the upper hand over its nation's hardliners, allowing Japan to submit to unconditional surrender prior to suffering total devastation?

An alternative history, Seatanks initially unfolds upon a backdrop of factual history. The story commences with Admiral Yamamoto a man who strenuously opposed those pushing Japan toward war with the West, yet when war became inevitable it was he who was the driving force behind the Pearl Harbor attack being introduced to a young naval officer and his ideas for a revolutionary weapons system.

All but one of the book's characters are real men of history. As the novel's central plot unfolds their actions become increasingly fictionalized. By the time the story reaches its conclusion, the great mid-Twentieth Century war between Japan and the United States has been significantly altered.
