Obayashi Corporation’s Investors’ Guide 2026 is a single 43-page booklet that lays out the whole company — its businesses, strategy, capital policy, and financials — in one place. This hub breaks that booklet down into 24 focused, plain-English articles, one topic at a time, using only the facts and figures printed in the guide. Start here for the big picture, then follow any link below for a detailed explanation.

What is the Investors’ Guide?

The Investors’ Guide is Obayashi’s periodic IR booklet that gives a full-company overview in one document. Unlike a quarterly earnings presentation — which focuses on the latest results — the guide is designed to help an investor understand the entire business at a glance. The June 2026 edition is organized into five chapters:

• 1. Overview of the Obayashi Group — company profile, global network, history, strengths, and value-creation process
• 2. Business Overview — the five business areas, the domestic construction market, and the overseas businesses
• 3. Medium-Term Business Plan 2022 — strategy, KPIs, cash allocation, capital policy, and investment plan
• 4. IR & SR Basic Policy — how the company engages with shareholders and investors
• 5. Appendix — five-year financial data, the balance sheet, and share-price / ESG information

Chapter 1 — Overview of the Obayashi Group

• Company Overview & Business Portfolio — the whole group in one view: ¥2,586.2bn in sales, and why 74.5% of profit comes from domestic construction.
• Global Network — sales by region: Japan 67.1%, North America 21.8%, Asia 10.5%.
• History — from 1892 to Tokyo Station, Skytree, and the Expo 2025 Grand Ring.
• Strengths — the Obayashi Three Pledges, the three “Powers,” and 8,000+ engineers.
• Value Creation Process — six forms of capital in, value to five stakeholder groups out.

Chapter 2 — Business Overview

• Domestic Building Construction — ¥1,138.7bn sales at a 9.1% margin, riding data-center and factory demand.
• Domestic Civil Engineering — ¥426.6bn at a 9.6% margin, backed by national-resilience spending.
• Construction Market & Big-5 Share — a ¥75.5tn market, a shrinking workforce, and the top-five contractor ranking.
• Workforce & Robotics Construction — Robotics Construction® and training as the labor-shortage answer.
• Overseas Construction Overview — ¥843.9bn sales and ¥1.2tn orders, but a thin 3.2% margin.
• North America — M&A-built growth to ¥564.7bn; GCON adds chip / data-center capacity.

• Real Estate Development — an 18.7% margin and roughly ¥287.7bn of unrealized gains on lease assets.

• New Business Domains — smart buildings, robots, and urban data centers.

Chapter 3 — Medium-Term Business Plan 2022 & Capital Policy

• Medium-Term Plan 2022 Strategy — two phases: strengthen the foundation, then accelerate transformation.
• MTP2022 KPIs — the full scorecard: operating profit ~2x target, ROE 14.4%.
• Cash Allocation — about ¥480bn of operating profit funding a ¥750bn plan.
• Capital Policy & Shareholder Returns — ROE 10%+, DOE ~5%, and a ¥100bn buyback.
• Cross-Shareholdings — ¥285.2bn sold in five years, heading below 20% of net assets.
• ¥750bn Investment Plan — where the money goes: ¥300bn to development, ¥190bn to tech / DX.

Chapter 4 — IR & SR Basic Policy

• IR & SR Policy — timely, fair disclosure and a feedback loop into management.

Chapter 5 — Financial Data & Appendix

• Financial Data — the five-year track record, FY2025 drivers, and the balance sheet.
• Share Price & External Ratings — share price versus TOPIX, and ESG index inclusion.

How to read this series

If you are new to Obayashi, we suggest reading in this order: start with Company Overview for the big picture, then MTP2022 KPIs to see where performance stands against plan, then Capital Policy & Shareholder Returns for how profits are returned to shareholders. From there, follow whichever business or topic interests you.
