25. Munitions storage

In association with the 41st Naval Guard Force base, two large revetted warehouses were located here. They were used to store munitions, torpedos and mines, before they were stored in caves. Only foundations and some of the earth revetments and this pillbox remain.

26. Refrigeration building

The area around here was known as Nanko and it contained the major pre-war fishing facilities for Tonoas, including this building which housed the refrigeration plant. The area operated as the Fourth Naval Dockyard during the war. The refrigeration plant operated up until 1945 when it was damaged by bombing.

27. Nukuno Pillbox

At the end of a concrete road built by the Japanese in the village of Nukuno, is located a good example of the many pillboxes in Chuuk. Constructed by the Japanese Army they were used to accommodate machine gunners in repelling the USA amphibious invasion which never came.

30. Operations / Communications building for Seaplane Base

While the majority of the Japanese war buildings were made of timber on concrete foundations, some, such as this building were of all concrete. This building was the headquarters and communications building / control tower for the seaplane base, and was built to withstand aerial bombardment. One of the chiefs, Menis Nion, of Kuchua watched from the hills nearby as the USA bombers attempted unsuccessfully to destroy this building in February 1944.

31. Seaplane base

The construction of the seaplane base began pre-war in about 1935 and took about four years to build by which time the Japanese Navy were back in control of Micronesia. Chuukese from many islands were forced into building the base. The two ramps that were used to retrieve the seaplanes can be seen either side of the dock and bunker, which has a school office perched on top of it. The seaplane base is now the location of the Tonoas high school.

32. Oxygen filling building

Substantial remains still exist of this concrete building that was used to fill Oxygen and Acetylene bottles. Menis Nion worked here as a janitor when it was operated by civilian administration. After the war the Chuukese landowners moved into the building as it was not greatly damaged by the bombing.
