Global Fishing Index

Japan

Japan has a developed fisheries governance system that, where applied, has the capacity to ensure sustainable fishing. However, Japan has made limited progress to restore fish stocks to sustainable levels, with half of its catch from unassessed stocks, with unknown levels of sustainability.

Japan is an archipelagic nation that consists of nearly 7,000 islands across vast ocean area. Japan has a long history of fishing in its productive coastal waters,1 and globally is the fifth largest producer of wild-caught fisheries.2 Japan is one of fourteen countries represented on the High-Level Panel for a Sustainable Ocean Economy – an initiative committed to sustainable fisheries and economic prosperity.3 

Japan has a developed fisheries governance system that, where applied, has the capacity to ensure sustainable fishing. However, clear gaps remain, particularly the limited use of science-based management measures. Overall, Japan shows limited progress to restore fish stocks. Half of the total catch in Japan’s waters comes from unassessed stocks, which lack the data to determine their sustainability. More than half its assessed stocks are overfished, including nine out of the ten largest stocks by volume. To advance towards SDG target 14.4, Japan needs to take urgent action to rebuild overfished stocks and strengthen science-based management.

Recommendations

Review the management measures in place for overfished stocks and take corrective action, where needed.
Expand the use of evidence-based management measures, such as catch and effort limits, across all fisheries.
Adopt a National Plan of Action to combat illegal, unreported and unregulated (IUU) fishing.
Eliminate all harmful subsidies and redirect investment into fisheries management.
Ratify and implement the 1957 ILO Abolition of Forced Labour Convention (No. 105) and the 2007 ILO Work in Fishing Convention (No. 188) to protect worker rights in fisheries.

Progress towards SDG target 14.4

While Japan performs in the top one-third of countries assessed globally in terms of progress towards achieving SDG target 14.4, it demonstrates limited progress towards ensuring all fish stocks within its waters are sustainably managed.

Japan’s relatively low (just 20.9 out of 100) Progress score is due to the fact that 50 per cent of catch in its national waters comes from unassessed stocks, that do not have official published assessments or sufficient data available to estimate stock health.

Only 28 of Japan’s 67 assessed fish stocks (42 per cent) are considered sustainable, defined as being at or above 40 per cent of their unfished levels of abundance. Critically, in terms of catch volume, nine of the ten largest stocks are overfished, including the Japanese pilchard (Sardinops melanostictus), Pacific saury (Cololabis saira) and Japanese anchovy (Trachurus japonicus). All sustainable stocks together account for 37 per cent of the total catch in Japan’s waters since 1990, compared to only 13 per cent of catch coming from sustainable stocks.

Fisheries governance

Japan performs in the top 10 per cent of countries globally and is among the top three countries in Central, Southern, Eastern and South-Eastern Asia for fisheries governance. Japan has a developed fisheries governance system that, where implemented, promotes sustainable fishing. However, clear gaps remain regarding the limited use of science-based management, provision of harmful fishing subsidies and lack of protection for worker rights and safety in fisheries.

Japan is a global leader in terms of stakeholder participation in fisheries management. Stakeholders are provided opportunities to participate through the decentralisation of management responsibilities to lower levels of authority – for example, through community-based or customary management arrangements at local and regional levels. Furthermore, stakeholder engagement is supported by transparent decision-making processes and widespread fisher representation groups (such as cooperatives or associations).

At a national level, Japan has a solid fisheries policy foundation with clearly stated environmental, economic and livelihood objectives, as well as a strong commitment to international standards for fisheries management and marine conservation. However, Japan is yet to ratify key agreements for protecting fisheries worker rights and safety, including the 1957 ILO Abolition of Forced Labour Convention (No. 105), the 2007 ILO Work in Fishing Convention (No. 188) and the 2012 IMO Cape Town Agreement.

Japan also continues to provide a diverse range of harmful fishing subsidies – such as reduced fuel prices and tax exemptions. In fact, close to 80 per cent of Japan’s fishing subsidy budget (estimated at nearly US$2 billion in 2018) are linked to potentially harmful activities that promote overcapacity and overfishing.4

There is evidence that Japan has financial and professional capacity to undertake fisheries management. For example, it collects high-quality fisheries information, such as catch, fishing effort and stock status data, for key fisheries like tuna. Science-based catch and/or effort limits to regulate fishing pressure have also been established in some, but not all, fisheries. However, evidence-based harvest control rules – pre-determined rules that guide management action, based on the state of fisheries resources – are not applied, even in the valuable purse seine tuna fishery (with the exception of pacific bluefin, Thunnus orientalis).

Japan uses a range of tools to control and monitor access to fisheries resources, including extensive vessel registration requirements and spatial restrictions, such as marine protected areas and coastal management zones that prohibit large-scale fishing operations. Most commercial vessels fishing in Japan’s waters are also required to hold valid fishing licences; however, this requirement is yet to extend to domestic, non-commercial vessels (for example, vessels used for recreational or subsistence fishing).

Foreign fishing is permitted in Japan’s waters through bilateral and/or multilateral agreements. While a very low level of fishing by foreign-flagged vessels was detected in Japanese waters in 2019, it included vessels operating under known ‘flags of convenience’, which often mask true vessel ownership and reduce accountability5; these are considered high risk for illegal activities. Japan has components of a solid compliance management system – including on-water and in-port fisheries inspections and graduated sanctions for fisheries violations – which may help mitigate risk associated with these vessels. However, Japan can further strengthen its compliance system by implementing a national plan of action to prevent, deter and eliminate illegal, unreported and unregulated (IUU) fishing.

Methods and data sources

Japan is considered part of the Central, Southern, Eastern and South-East Asian region. Refer to the Technical Methods for a detailed explanation of the methods used by the Minderoo Foundation to produce the 2021 Global Fishing Index. The Technical Methods should be read in conjunction with the Global Fishing Index Key Insights report, Governance Conceptual Framework and Indicator Codebook.

Japan’s Progress score was informed by 67 assessed fish stocks. Seven stocks had recent published official stock assessments, all from regional fisheries management organisations (RFMOs). The remaining 60 stocks were assessed using publicly available data and established data limited methods (CMSY++ or the Bayesian Schaefer Model).67 Catch and stock sustainability estimates were reviewed by one local fisheries expert, prior to finalisation.

Japan’s governance assessment was informed by two questionnaire respondents, interviews with three local fisheries experts and the publicly available literature. Consulted references are listed in the bibliography below. Our governance assessment measures country-level fisheries governance, with eight indicators referring specifically to a country’s most valuable fishery, as identified by respondents. The most valuable fishery identified for Japan was the purse seine tuna spp. fishery.
