SECOND SUPJPLELISRTCINCPAG-CIKCPOA BULLETIN No, 53-45I. SUMMARY;

(See Map - Principal Installations - OKINAWA GUNTO)A new -airstrip is under construction near ITOlvIhlf - Townon southern OKINAWA Siiirna, and an emergency landing area,not previously reported by this activity, is on KUME Shima,Construction on the Y0NA3ARU Airstrip apparently is discontinued. The other airfields in the G-unto, IE Shima, NAHA,YONTAN, KATENA. and MACHIIUTO, remain operational, but somedamage has been done to their facilities. The report ofan airfield being under construction on IZSNA Shima of IHSYARetto is discredited by recent photographic coverage.Recent photographic coverage confirms the report that

the final air strikes of 10 October 1944 caused widespreaddamage and destruction by fire at N A H A Town, TOGUCHI (onnorthern OKINAWA Siiiica) and ITQM^N T^wns also are damaged.Air defenses are concentrated around the NAIIA, YONTAN,and KATENA Airfields, Ground defenses are concentrated inthe YQ1CTAN-KATSNA area and the ILVKAGUSUKU V/an area.Only ninor military activity is observed in theRetto, arid little or no activity is observed on AG-UNI siiima,TONACHI Shimay IZSNA Shiina, and the KEISAN Shu.

The ialands, forthe most part, ere composed of uplifted material: 'sandstone, limestone, slate, etc. They rise as cliffs or steepslopes; the four beaches of any length occur at trie mouthsof steep valleys or within small bays. With the exception of a few cultivated areas, the islands are coveredwith.brush and tree;;. Snail mixes operate on YAJKABI Shina,

and KUBA Ghiua. A fringing reef of irrsgular width surrounds each inland,B . ESTHvIATBI) TROOP DISPOSITIONS

From a study of aerial photographs covering the KSRAMARetto dated 22 January 1945, there appears to be no military installations and no military activity to dato on thefollowing islands: AKA, AMUHO, FJKASHI, GIStflBIJ, EERXJM4,KOBA, and ZAMAMI.Except for haze over two of the islands, the photo

graphs were gonerally good and of a scale of i/5000. However, failure to observe activity or installations fromthe photographs should not be construed to indicate complete absence of military personnel. If thi usual practice of the Japanese Las been followed, there are probably coast watchers and lockouts stationed on each of tholarger islands, numbering approximately 15-20 men pur island .On YAKAIJ, the westernmost island of tho r^tto, thoreis a radio station, in the vicinity of the mine, consisting of a small building and two stick-typo masts. This

station is probably inannod by military or naval cornmimioiu"tions personnel totaling epprozimatoly 20-30 men.On T01OIS1IIKI back of the town of TOICASHIiOJ on the ;\.?stcoast, eight buildings which appear to be Kiska-typo barracks iia^e boon constructed doep in protective ravinesand camouflaged. Ono group of four buildings are similarin dimensions to naval barracks found at ElSKA and theirtotal capacity is estimated to be approximately 200 me n.Tho ether group of tour buildings are similar 'n dimensions to army barracks found at KISKA and th;.jir totalcapacity is osi/i'matcd to be approximat-ily 600 men. Efforts to locate the gun installations and prepared positions for the troops- probably quartered in these' supposedbarracks have bo^n unsuccessful. One definite section offirw trench was observed on 0TliIJA Mountain spproxiiuately1600 yards south of and overlooking tho town of AWAKK.This position, however, had only four foxholer? and a coinmunicction trench leading to a personnel shelter. Pathactivity and scarred earth on the peak of tho high groundinland from OIZUNO Saki and 1,000 yards north of the townof TCKASHT.KI, on tho cast coast, indicate that field fortifications r;ro possibly under construction there. Along

tho beach forward of the town of TOKASHIKU, which iy mostvulnerable to the barracks area, there is much path activity and scarred earth. This could be a natural .consequence35

A small streamruns into the se-'x near the northeast corner of the island.With the exception of some low areas in the southern andeastern part, the shoreline rises as cliffs or steep wooded slopes. Only small pecket-beaohes occur along the steepparts.of the coast, A line of rock outcrops extends 5/&of a mile south from tho southern tip of AKA Shima. Afringing reef surrounds the island. AKA Shima is separated from GERUMA Shima to the. south by a narrow shallowchannel.

Tho village of AKA Und some fields of rice and drycrops cover the floors cf two small valleys at the southern end of the island. A cart track leads from AKA throughthe valley to the east to some small underground entrancesbehind the beach on the eastern coast.At AKA Village there is a 750-yard beach, most of whichis blocked by coral lodges juat off shure. The sandy pointextending south toward GERUMA Shina is comparatively unobstructed, avt AKA a 165-yard stone seawall backs part ofthe beach; the rest slopes up to the town itself.

Along the eastern coast north cf H A N T A Yaraa is a620-yard be:-.eh, most of which is backed by a low grass-covered riso. Three tracks eight ft. wide have been cutthrough this rise and another angles over it; all of thesele??cl to a track parallel with the beach that serves themouths of numerous underground excavations, then windswestward through the cultivated valley to AKA. In conjunction with this, about ten 15 f x 8 f vehicles dispersedin the area may indicate a possible amphibious tank base,GERUMA SHIMA (KERUIvU SHIMA)GERUMA Shiran, is nearly round and 5/B of a mile in diameter. It rises in steep slopes and cliffs tc an elevation of 45^ ft. The village of GERUMA, at the southernend of the island, is built on a snail flat, where twoshort vrlloys reach the soa. The valley sides and bottomsare planted in rice and other crops. Harrow shallow channels .separate GERUMA. Shima from AKA Shima to the north andHOKA-JI Shiiia to the south. The island is nearly surrounded by r! fringing reef.The only beac'fc of any size (170 yds.) lies along thefront cf GERUMA Village. It is backed by a stone seawall,

KXJBA SHIKA (KOBA JIM A)KIJEA Shima is lj miles long, -north-south, and about 1/2mile wide. The entire coast is bounded by cliffs and steep

slopes. A mountain at the southern end rises to 800 feet,while a small semiplateau at the northern end reaches about300 feet in height. Bare, rocky crags characterize theextreme southern slopes; the central part is voodod; and. onthe northern plateau there is some cultivation and a smallgroup of buildings". On the slope, at the center of thewestern side of the island, there is a mine, and at thewater's edge, a 60 ft. pier. A fringing reef bounds all ofthe island except the southwestern tip.The group of buildings on the plateau includes acamouflage-painted power house and another larger camouflaged building. Most of the other structures appear tobe workers1 quarters. From a small building on the eastern edge of the plateau a steeply inclined track rune down to a short beach. There is possibly a narrow gaugerail line on the incline. A line of poles runs from thepower house, near this small building, and down the hillside to the ber.eh. A short distance south of the lowerend of the incline there is a building at.the beck of thebeach.A line of poles also runs west from the power house

to some mine buildings on the western hillside, possiblycontinuing to a pump or springhouse near the foot of theslope.From some tunnel entrances of the mine a trail runsto a chute that empties into a building stuck on the hillside. Other buildings farther down the slope apparentlyprocess material from lower tunnels and dump a fine whitematerial into a pile at the foot of the slope. The stonepier (60 ft. x S ft. ) , apparently bearing a narrow gaugerailway, projects into the water at this point. The seaward approach to the pier is through large coral heads.A well-worn trail runs from the nine to the settlement and east to the head of the incline. Other trails rundown the hill, neraiVithe incline, to the beach and from thesettlement a short distance up the hillside to the south.There are only three beaches offering any possibilityof exit. They are at the eastern end of the incline (150yds, long), on the north coast (150 yds . long) and justnorth of MOTOSENO Saki on the western coast (210 yds. long).All are backed by steep slopes; trails lead up the hillsides from the eastern and western beaches.KUBACHI Shima is a snail rocky promontory at the northend of KUBA Shina, separated from that island by a verynarrow strip of water. A line of rock pinnacles runs west400-500 yards fron MOTOSENO Saki, on KUBA Shina.
