Oil Refinery Throughput โ - Oil Refinery Throughput refers to the actual volume of crude oil and other refinery feedstocks processed by petroleum refineries during a given period. It is typically measured in thousand barrels per day (kb/d) and represents the operational output of the refining sector rather than its installed capacity. This indicator reflects the extent to which refinery infrastructure is utilized to convert crude oil into refined petroleum products such as gasoline, diesel, jet fuel, kerosene, fuel oil, liquefied petroleum gas (LPG), and other petroleum products. Oil Refinery Throughput is widely used to assess refinery operations, downstream petroleum activity, fuel production levels, and the efficiency of refinery utilization.
It serves as an important indicator of refinery utilization, fuel production, industrial efficiency, energy security, and Japan's ability to meet domestic petroleum product demand.
Japan recorded oil refinery throughput of 3.26 million barrels daily in 2015, increasing slightly to 3.28 million barrels daily in 2016 before declining to 3.21 million barrels daily in 2017. Throughput decreased further to 3.06 million barrels daily in 2018 and 3.05 million barrels daily in 2019. In 2020, refinery throughput fell significantly to 2.49 million barrels daily because of reduced transportation fuel demand and operational disruptions during the COVID-19 pandemic. Throughput remained unchanged at 2.49 million barrels daily in 2021, recovered to 2.69 million barrels daily in 2022, and eased slightly to 2.55 million barrels daily in 2023, reflecting stable refinery operations and evolving domestic fuel demand.
Overall, the dataset demonstrates a gradual decline in refinery throughput throughout the review period, interrupted by a significant pandemic-related downturn and a partial recovery in subsequent years. The trend reflects changing energy demand, refinery optimization, and improving operational efficiency.
The dataset is valuable for evaluating Japan's refinery throughput trends, analyzing downstream industry performance, and assessing crude oil processing activity. It supports refinery utilization analysis, investment planning, energy security assessments, and policy evaluation while providing valuable insights for researchers, analysts, industry stakeholders, and policymakers studying refinery efficiency, infrastructure utilization, and the long-term competitiveness of Japan's petroleum refining industry.
