The memory of the battle of Okinawa was shaped by politics. The memory of the battle for Okinawans emphasizes war crimes committed against them and the devastating impact that was inflicted upon their peaceful island. Their emphasis on sole victimization led to other Okinawan narratives being either downplayed or outright denied. To remove American bases off their island, gain recognition for Japanese atrocities plus reparations, the Okinawans portrayed themselves as a peaceful people that were the sole victims of the battle of Okinawa. The United States glossed over the crimes committed by the Japanese on Okinawa and Asia to use Japan as a bulwark against what they perceived as communist aggression in Asia. To solidify this new alliance, the United States promoted reconciliation instead of punishment. In doing so, they willingly forget atrocities committed by the Japanese against Asian nationals. Americans also remember the battle in conjunction with the dropping of two atomic bombs and to justify their morally superior position to the Soviet Union, promote a more complex picture of the decision to use the bombs. This included discussing how Okinawa changed the American leader’s perspectives on a mainland Japan invasion. As a result, has become increasingly difficult to separate Okinawa and the bombs because of their temporal closeness. The Japanese tend to remember the battle as a heroic last stand and emphasize sacrifice to inspire future generations partly out of fear that Japanese youth have gone soft, ultimately demonstrating that Japan has not fully come to terms with her memory of the Second World War.

Abstract In order to understand the source, transport pathway and sink of settling particulates off northeast Taiwan, time-series sediment traps (PPS-3/3) were deployed on the north slope of Ilan ridge (T18) and in the Okinawa trough (T15 and T16) to collect settling particulates. The trapped particulate samples were determined for apparent mass flux (T18), particle size distribution, and contents of lithogenic portion, metals (Al, Mg, Ca, Fe, Mn, Cu), opal, OC (organic carbon) and IC (inorganic carbon). The results show that mass flux in winter is higher than in summer except for typhoon or rainstorm in summer which may cause high particulate flux. At mooring T11 and T17, only 2 cups had collected particulates but with rapid decrease, and the remaining cups were empty. It is not clear whether Kuroshio plays a role and further investigation is needed. The trapped particulates were mainly clay and silt in the north slope of Ilan ridge and south Okinawa trough, and were sand and silt in the Mien-Hwa canyon. The portion of coarse silt and larger particles (>31 mm) decreases with an increase of distance from the land (from T11 to T18). The grain size distribution of particulate at T18 is similar to that at T15 and T16, but the mass flux in the north slope of Ilan ridge is an order of magnitude higher than in the south Okinawa trough. The size distribution pattern below 600m water depth is very similar at both T15 and T16, but the coarse fraction (> 31 mm) is more at the upper than lower traps, presumably due to lateral transport. The Mn content of the trapped particulates in the south Okinawa trough is twice as hign as that in the north slope of Ilan ridge. High Mn/Al ratio in the trough suggests that Mn is supplied by hydrothermal activities. Lithogenic portions occupy about 84~88.5% at T18, T16 and T15. Relative to other marginal seas biogenic contributions are clearly lower.

Abstract The research was conducted as a part of the phase III of the KEEP(Kuroshio Edge Exchange Processes)program. Two strings of sediment traps were deployed simultaneously: one near the outlet of North Mien-Hua Canyon (T15), and the other at the south rim of the South Okinawa Trough (T16). The purposes are to collect settling particulates at various depths for the studies of temporal and spatial variations of the particulate flux, 210Pb activity, 210Pb flux and size distribution. The particulate fluxes showed synchronous variations among the traps deployed at different depths of the same site. In general, the particulate flux in the marginal sea areas increases with depth but the maximum values may be at the mid-depth rather than at the deepest trap and remain so for the entire mooring period as observed at T15 and T16. Unusually high particulate fluxes could occur within the same period, probably reflecting an episodic event, such as typhoon or rain storm. 210Pb activity measured from different depths at T15 and T16 increases generally with depth along with the increase of the particulate flux toward the bottom. The temporal variation of 210Pb activity is generally smaller than that of the particulate flux in terms of relative amplitude. At the outlet of the canyon, T15, the temporal mean particulate flux of each trap ranged from 0.16 to 3.3 g/m2/d(a factor of ~ 20), while the mean 210Pb activity of each trap varied from about 98 to 168 dpm/g. At T16 located at the south rim of the South Okinawa Trough, the temporal mean particulate flux ranged from 0.06 to 5.7 g/m2/d(a factor of ~ 100), while the mean 210Pb activity varied from 82 to 192 dpm/g. The particulate 210Pb flux was smaller at T15 than at T16 because T15 has smaller particulate flux. The trapped particulates in the canyon(T1-T3) are mostly silt and sand, while the particulates collected from the Okinawa Trough(T15, T16) are mainly silt and clay. The 210Pb activity of the former is much lower than that of the latter, indicating the enrichment of 210Pb on the fine particulates. As the fine-grained particulates away from landmass have longer residence time in the ambient water, they can scavenge 210Pb more effectively.

In this study, the settling particulates collected by time-series sediment traps, sediment cores, and seawater samples taken in the western South Okinawa Trough were analyzed for 210Pb and 210Po in order to understand the characteristics of the particulates and sediments based on the distribution of these two nuclides and the extent of their radioactive disequilibrium. Two sediment traps were deployed at T18 (24¢X45'N 122¢X18'E, about 300m and 100m above bottom) from February to August 1999. The results show that higher mass fluxes were observed from February to April, ranging between 16 and 56 g/m2/d. The 210Pb activity increases systematically with time from about 80 to 100 dpm/g, and the upper trap has slightly higher values. Similar to 210Pb, the 210Po activity also increases, but from near zero to only 27 dpm/g for both traps, much lower than the corresponding 210Pb activity. The 210Pb activities are quite different between the settling particulates collected by traps at T18 and the surface sediment taken nearby (the former have a mean activity of about 85 to 90 dpm/g; the latter has a value of only 11 dpm/g). The size distribution and elemental composition are also different between the trapped particulates and the sediment. Thus the underlying sediments were not directly derived from the overlying trapped particulates. Except for T4 core below 15cm and T19 entire core, the 210Po/210Pb activity ratio in the sediments varies greatly, from near zero to 0.7, indicating deficiency of 210Po. Both 210Po and 210Pb activities are much lower in the sediments than in the settling particulates. A T19 both 210Po and 210Pb activities in the core decrease steeply from 120 dpm/g at surface to 60 dpm/g at 4 cm, indicating radioactive equilibrium. This is entirely different from the cores taken at other stations. The total 210Po/210Pb activity ratio in the water column at T17 is nearly constant at about 0.6, but drops to 0.3 below 700m, i.e. 210Po activity is deficient in the entire water column. At T18, the activity ratio is about 1.3 between 100m and 300m, indicating a 210Po excess in this layer. Below 400m, the ratio is about 0.6 to 0.7, showing 210Po deficit again. These observations indicate that the water columns at T17 and T18 are stratified, probably due to lateral transport. Based on the 210Po/210Pb activity ratio the mean residence time of 210Po with respect to particulate scavenging ranges from 3 to 16 months.

Social and political life on small subtropical islands is frequently shaped by the economic imperative of sustainable tourism development. In Okinawa, “ecotourism” promises to provide employment for a dwindling population of rural youth while preserving the natural environment and bolstering regional pride. In this dissertation, I consider how new subjectivities are produced when host communities come to see themselves through the lens of the visiting tourist. I further explore how Okinawans’ sense of place and identity are transformed as their language, landscapes, and wildlife are reconstituted as “cherishable,” yet vulnerable resources. I present a case study of how local ecological knowledge moves inter-generationally (between Okinawan elders and youth) and cross-culturally (between Okinawan nature guides and international and mainland Japanese tourists, who are often also considered “foreign”). By tracing the formal and informal social networks through which specific attitudes, beliefs, and sensibilities about the environment are circulated and reproduced, I demonstrate how nature-based therapies marketed to tourists for stress relief and lifestyle rehabilitation (e.g., forest therapy, dolphin therapy, and coral “gardening”) also influence Okinawan attitudes toward health and wellness. These kinds of activities reconfigure human relationships with non-human animal species; creatures previously “good to eat” (Harris 1985) are now even better to heal. “Sustainability” in Okinawa always begins with the question of military bases. The ecotourism concept poses a compelling, if problematic, economic alternative to the expansion of US bases into northern Okinawa, the hub of environmentally oriented conservationist, educational, and tourist programs on the main island. My analysis of the ecological and cultural effects of sustaining the tourism industry in Okinawa speaks to small islands facing similar economic and environmental challenges in East Asia, the Caribbean, Oceania, and beyond. / Anthropology

This doctoral research is a contribution to the understanding of social activism and its socio-cultural formation in postcolonial Okinawa. It is based on eighteen months of fieldwork including participant observation and interviews at a public women’s organisation, Women’s Organisation Okinawa (WOO). This project centres on the lived practices of staff who attempted to produce and encourage gender equality in the public sector under neoliberal governance. I demonstrate through ethnographic analysis how the practice of law and social movements is distinct from the ideals of such movements as well as the particular individuals involved in them. WOO was established in the public sector by local government in alliance with various grassroots groups in Okinawa in the late 1990s. WOO embraced the dreams, hopes and anticipations of various actors - users and workers - who had been involved in the establishment, but in reality, it also contained various contradictions. First, WOO was a new workplace for those who wanted to work in activism and be paid for their work, but also reproduced precarious, low-waged, gendered labour. Second, WOO was a site which put law into practice, but it revealed that law internalised the inconsistency between what people had originally expected of the law and what law enacted as a result of institutionalisation. Third, WOO unexpectedly became a focal point of contact between neoliberal and feminist governance through public services and the requirements of performing accountability for citizens and for feminist activism. Thus frontline practitioners attempted to bridge the gap between ideal, reality, law and practice and to negotiate with neoliberal and feminist governance in the labour process. This thesis demonstrates how the inconsistencies between ideal and reality arose in the daily working practices of staff positioned between citizens, laws and social movements. More precisely, it explores how staff attempted to negotiate, accommodate and struggle with the gap between ideal and reality through their lived experience, rather than fiercely resisting or merely being subject to a form of governance or reality. In doing so, the thesis reveals how unstable and problematic the notion of ‘gender equality’ was as it was deployed at WOO.

Patrick Henry and Thomas Paine might have been better equipped to understand the Okinawan reversion movement than are most Americans today. Many Americans in Okinawa wonder why, in the light of the obvious military and economic advantages of American occupation of the Ryukyus, an over- whelming majority of the Ryukyus wish to return to Japan. The question includes, of course, a full periphery of qualifications relating to degree and schedule of withdrawal, but the fact remains that no Japanese or okinawan politician dares oppose eventual reversion.
