Japan’s new Infrastructure Revival Policy (2024–2030) requires ISO-14001 certified equipment. We recommend:

- Hokkaido Industrial – Offers 0% financing for Okada rigs
Both suppliers provide free buying guides with custom cost projections. Limited-time deal: Orders placed before March 2025 get 3% tax rebates.
