Mooring the global archive is an act of historical inversion. Instead of starting from the nation-state and radiating outwards, Martin Dusinberre begins with a single ship – the Yamashiro-maru – and follows the wakes cut by migrants, merchants, and officials across the Pacific world. At first sight, it appears to be the history of this single vessel, built in Newcastle upon Tyne for Japan’s Kyōdō Un’yū Kaisha (later NYK) and folded into Meiji ambitions for maritime recognition. It also appears to be the story of the Japanese migrants who sailed aboard it, whose career ran from passages to Hawai‘i and Australia to wartime logistics in the Sino-Japanese War, before it was declared ‘obsolete and uneconomic’ in 1908 and later sold for scrap.Footnote ¹ But readers soon discover through this ship that Dusinberre, stitch by stitch, unsettles the usual story we tell about modern Japan, that is industrialization at home and empire abroad. Instead, the author insists that migration, contract labour, and maritime infrastructures, long treated as peripheral to Meiji state-building, belong at the centre of that narrative.

Recentring migration within modern Japanese history and within the growing literature on the margins of the pre-war Japanese empire, the book offers an oceanic microhistory. It is very much at home in the Cambridge Oceanic Histories series and models a reflexive, often imaginative, materially grounded way to do global history in the digital age, precisely the direction in which much of the field is travelling.

Dusinberre names three ‘archival traps’, familiar to many historians, that the author was caught in and worked his way out of: the lure of writing a ship’s ‘life’ as an object biography; the assumption that ‘the global was googleable’ given the abundance of digitized material; and the tendency to privilege text while overlooking the material and multilingual contexts that give language its force.Footnote ² The discussion is not a scolding of others so much as a mapping of his own practice, and it opens on to a broader methodological claim that historians should moor the global archive. They should do it not by multiplying sites indiscriminately, but by attending to the material, legal, and political sites that make sources legible, and by disclosing their ‘authorial metadata’ in the Blochian sense – how we came to know what we claim to know – which is the book’s most original contribution.Footnote ³ A serendipitous gravestone of a Japanese migrant labourer at Kapa‘a, Kaua‘i (Kodama Keijirō) becomes the ‘mooring berth’ for a transpacific narrative. It becomes an entry point that foregrounds contingency, access, and the ethics of narration, and that immediately leads into consular paperwork, immigration ordinances, and company records, showing how micro sites can re-anchor global histories in the workings of the state.Footnote ⁴

Read through the lens of empire, global history, and archival traces, the book’s claim is that modern Japan cannot be understood without the governance of mobility at sea and on shore. The state here is not a purely territorial bureaucracy. It is an actor embedded in oceanic systems – shipping firms, port authorities, consulates, immigration regimes, and plantation discipline – whose routines and records both produced and constrained the category ‘Japanese’ abroad. In taking archives as objects of analysis rather than neutral repositories, the book also demonstrates that what we can know about empire depends upon legal and material regimes of access that are themselves imperial infrastructures of rule.

We see this most clearly in chapter 2, in the move from yard to voyage and landfall. Using a plantation painting and fragments from two Yamashiro-maru migrants, Dusinberre reconstructs the ‘in-between’ of ocean crossing. At sea, the ship functions as a mobile bureaucracy, arranging bodies, time, and space well before the port is reached. On arrival, the port is the site where immigration routines and labour contracts convert heterogeneous villagers into an administrative identity classifiable by consuls and immigration boards. Because the ocean crossing leaves few direct traces, Dusinberre pieces the story together by reading a plantation image alongside landing records and later files to show how mobility was governed by a public–private nexus in which company schedules and the captain’s authority converge with consular routines, Board of Immigration rules, and plantation discipline. Empire appears less as paperwork, categories, and classification, and more as infrastructures and routines through which sovereignty is exercised and labour made extractable.

One of the book’s strengths, and one of its interventions, is its re-periodization of Japan’s ‘opening’. Beginning with coal seams, special export ports such as Karatsu and Kuchinotsu, and coaling hubs such as Wakamatsu, Dusinberre shows how energy logistics bound ship-centred histories to subsoil infrastructures. The familiar image of Commodore Matthew Perry’s ‘black ships’, long taken to mark the opening of Japan in 1853–4, recedes as black smoke comes to the fore. This is a powerful reframing with clear implications for surveys and teaching. Accounts of opening and expansion need to bring subsidy policy, coaling networks, and port governance into the same frame as diplomacy, and to treat port-city and energy archives as central sources rather than background context.

Equally distinctive is the book’s reflexive approach to the archive. Its discussion of ‘archival traps’ and its insistence on ‘authorial metadata’ matter for more than questions of craft, because they make explicit the political and material conditions that structure what counts as evidence and what kinds of lives can be retrieved. By showing how access, language, and description are themselves products of power, Dusinberre masterfully turns the archive into a site where imperial relations are reproduced and, at times, contested. This method does not merely thicken context. It argues that global history explains more when it specifies the consular, corporate, and colonial regimes that govern the circulation of documents and the terms on which they can be read.

There are, however, points where the argument strains in ways that are productive for debate. Dusinberre is most explicit about how empire worked through ships, schedules, consulates, cartography, and coal. The author is less concerned with theorizing, or engaging directly with, the historiographical debate over what kind of imperial project Meiji Japan was pursuing. That leaves much of the synthesis to readers already familiar with debates on the historiography of the Japanese empire and its histories of migration. The trafficking networks that moved women like Hashimoto Usa through Southeast Asian ports relied on British colonial hubs such as Singapore and Hong Kong. Japan’s informal empire of migration and commerce often travelled along the infrastructure of Britain’s formal empire. After all, the vessel at the heart of this story, the Yamashiro-maru, was British-made and assessed against British standards such as Lloyd’s Register. Japan’s maritime expansion, a key mechanism of its empire, was initially dependent on the industrial and technical infrastructure of the world’s dominant empire. By setting up lodging houses, businesses, and eventually consulates in these hubs, Japan effectively latched on to that imperial infrastructure.

The Hawai‘i Japan axis is developed in real depth, but contemporaneous routes to the US West Coast, to Canada, and to other Pacific islands receive no attention. If the central claim is about how states and para-states governed mobility, a more direct inter-imperial comparison of Japanese, American, and British colonial legal regimes, alongside consular protection and surveillance, and the role of shipping subsidies and classification rules, would strengthen the argument that empire operated through relationships rather than in parallel tracks. The book points to much of this material. Bringing it into the foreground alongside Hawai‘i would illuminate not only variation but also how techniques of rule travelled.

Relatedly, the analysis privileges local colonial encounters to great effect, but the inter-imperial field sometimes recedes to the backdrop. Diplomatic friction around the 1894 Anglo-Japanese treaty and its impact on Australian immigration, and the reframing of Perry’s mission as a contest over coal, point towards a wider chessboard. Yet the high politics of empire, including how British shipping interests responded to state-subsidised NYK routes, or how naval planners in London and Washington assessed Japan’s growing maritime capacity, remains largely offstage. Bringing those reactions into the same frame as plantation contracts and port procedures would sharpen the claim that the governance of mobility was constitutive of state relations, not merely coincident with them.

The assembled archive is read with care and often against the grain, but its architecture imposes limits that the narrative cannot fully escape. Chinese and Pacific Islander labourers remain at the margins of the story, though Chinese migrants in particular function as a key comparator in Japanese officials’ thinking. Yet the experiences and interactions of these other non-white subjects, including competition or solidarity in cane fields, sit largely outside Dusinberre’s frame. That constraint is not a failure of research so much as a structural feature of surviving records. Still, naming it as such and signalling how future work might widen the comparative frame would underscore one of the book’s most important lessons: even a critical ‘global archive’ risks reproducing the hierarchies of attention embedded in imperial documentation.

Finally, Dusinberre blends personal voice, interpretative speculation, and historical citation in a fluid narrative style. While this approach lends much of the book an engaging literary quality, it also muddies the distinction between archival interpretation and imaginative reconstruction. The result is suggestive but difficult to evaluate, particularly when the historian’s framing is layered over a sparse or partial evidentiary base. This prompts the question: how, in practice, does Dusinberre draw the line between imaginative reconstruction and evidentiary warrant when the archive is thin, and what tests does he apply when inference risks outrunning proof?

None of these desiderata detract from what the book achieves. They only indicate how high a platform it builds. Mooring the global archive is that rare scholarly work with its engaging exercises in archival juxtaposition, offering a creative and often moving account of how lives can be reconstructed from both official and vernacular traces. If it changes how we read lists, maps, and records, it also changes what we expect of ourselves as historians and how we bring our narratives to life.
