These four companies have very weak management bases, and because it is difficult to manage their business only with railway services, they are aiming for better profits with support from the government, such as funds for stable management, and by diversifying railway-related businesses.
これら4社は経営基盤が脆弱であり、鉄道事業だけでは経営が難しいため、経営安定基金などの政府の支援や、多角的な関連事業の展開により、利益の向上を目指している。
