Nikkei Industry Sector
Petroleum & Coal Products
Overview
Japan's oil and gas sector within the Nikkei 225 includes refining companies and petroleum product distributors that form a critical part of the national energy supply chain. As Japan imports virtually all of its crude oil requirements, these companies play an essential infrastructure role in converting raw imports into usable energy products.
Current Trend
Japanese oil refiners are diversifying into renewable energy, hydrogen production, and sustainable aviation fuel (SAF) to manage the long-term energy transition. The strategic pivot from fossil fuel dependency toward cleaner energy infrastructure is accelerating, with major companies committing significant capital to new energy businesses.

Position in Japan
The sector operates in a structurally challenging environment—declining domestic fuel demand from efficiency improvements and electrification, combined with refining margin volatility. Government energy security policy continues to support domestic refining capacity, while consolidation among major players has created stronger, more diversified energy groups.
