17. Fourth Fleet Headquarters

The remains of the headquarters and accommodation for fourth fleet commanders are located here, the last commander being Vice Admiral Chuichi Hara, who signed the surrender documents on the USS Portland with the Army Commander, Lt. General Shunzaburo Mugikura. The low concrete foundations are from the commander's residence, the nearby concrete foundation pillars are reported to be from a building that occasionally held the fleet band. On the very top of the hill above is located a small bunker where the Vice Admiral sheltered during the bombing of the base (see photograph). The buildings were damaged during the US bombing.

18. Memorial near Fourth Fleet Headquarters

The text on this memorial stone is written in an elegant form of kanji. It contains a Japanese poem dedicated to a special person, possibly a paramount chief of Tonoas, and dedicated in 1916.

19. Formosan Bank

This was the site of the second bank established by the Japanese, during which time it was a single story building. Although the land was owned by Ysauo Reseky and his family, no rent was paid. Another of the chiefs of Kucha on Tonoas, Yoda Chaniel, worked at this bank as a boy delivering messages.

20. Department of Finance and Department of Planning

Concrete foundations remain of two large, two-story timber buildings that accommodated personnel working for the Departments of Finance and Planning. Chuukese families now utilise some of the foundations for their use.

21. Japanese Army Headquarters

When the 10,000 plus Army personnel arrived in January 1944, they caused considerable aggravation amongst the indigenous population, still remembered today. Lt. General Mugikura removed the chief and his family from his home in Roro and established it as his headquarters. A nearby field was established as a park for playing baseball. A large bunker was dug to form an extensive shelter during the bombing. (see photograph).

Roro was also the location of the main water supply (from streams) on Tonoas and the Japanese dams are still in use today.

22. Cemetery and shrine

This shrine is a memorial to the many Japanese that were cremated and buried nearby, before and during the war.

23. Caves for suicide craft

Japanese craft filled with bombs, or utilising torpedos, were hidden in caves. They were used as suicide craft to attack and sink enemy ships that entered the lagoon.

24. Japanese road

While many of the Japanese war remains, such as building foundations are being re-used by Chuukese, other facilities, such as some of the Japanese roads have received little use. Evidence of this road to and from the early storage of munitions can be seen in the line-up of the coconut tress that once flanked the road.
