It was subsequently released in more areas of the U.S. on January 12, 2007, and was released in most states on January 19. An English-dubbed version of the film premiered on April 7, 2008. Upon release, the film received critical acclaim and although it only grossed slightly better at the box office than its companion, it was much more successful compared to its budget. In 2005, Japanese archaeologists explore tunnels on Iwo Jima, where they find something in the dirt. Iwo Jima, 1944. Private First Class Saigo, a conscripted baker who misses his wife and daughter, is digging beach trenches with his platoon when Lieutenant General Tadamichi Kuribayashi arrives to take command of the garrison. He saves Saigo from a beating by Captain Tanida for being "unpatriotic", and orders the garrison to tunnel underground defenses throughout the island. Kuribayashi and Lieutenant Colonel Baron Takeichi Nishi, a famous Olympic gold medalist show jumper, clash with the other officers, who disagree with Kuribayashi's defense in depth strategy. Kuribayashi learns that Japan cannot send reinforcements, and thus believes that the tunnels and mountain defenses stand a better chance for holding out.
