Hokkaido Offshore Wind Supply Chain: 27 Firms Mapped Against a JPY 768bn Target
Hokkaido’s first offshore wind supply chain map lists 27 firms, 18 based in Hokkaido. Local strength is in foundations and installation; the JPY 768bn target counts O&M.
Floating Construction Platforms for Japan’s Offshore Wind: Can Logistics Move Offshore Instead of Expanding Ports?
MLIT modelling puts 1 GW of floating wind on the Sea of Japan at 3 quays and 12 fabrication lines. A JETRO-backed study asked whether a relocatable floating platform can buy time instead.
REACH Launched in Kitakyushu: What Japan’s First Operational-Anchor Offshore Wind Cluster Means
REACH launched in Kitakyushu on May 22, 2026 — ~50 companies anchored to Japan’s largest offshore wind project. What the cluster means for domestic supply chain readiness and floating wind.
Japan’s JPY 370 Trillion Growth Strategy: Where Offshore Wind Sits in the 17 Priority Fields
Japan’s new growth strategy targets ~JPY 370 trillion in public-private investment across 17 priority fields by FY2040. Offshore wind sits at the intersection of five of them. What the industrial opportunity actually requires to convert.
GWEC Global Offshore Wind Report 2026: Japan’s 3.5 GW Forecast and the FID Barrier
GWEC’s 2026 report forecasts Japan offshore wind at 3.5 GW by 2030. The 10 GW gap is a correctable policy design problem — not a market failure. Auction recalibration is underway.
The Total Withdrawal Pattern: Why Mitsubishi Wasn’t an Outlier
TotalEnergies has exited US offshore wind ($928M) and is withdrawing from 7.5 GW of German leases within two months — a pattern that reframes Japan’s Round 1 withdrawal.
Offshore Wind Cost Is About When You Lock the System, Not What You Buy — Hitachi Energy × Ørsted and the Shift to Integrated Execution
Hitachi Energy and Ørsted’s April 2026 partnership signals a structural shift in offshore wind: from fragmented procurement to integrated execution. Japan implications.
Japan’s First Offshore Wind Tower Factory, Akita Blade Failure, and MLIT’s Floating Wind Installation R&D Program
Komaihaltec opens Japan’s first offshore wind tower factory, a second blade failure in Akita raises O&M concerns, and MLIT launches floating wind installation R&D funding.
The “10-Day Loss” Typhoon Risk: FLOWCON Exposes the Harsh Reality of Japanese Floating Wind Construction and the Path to 15GW
DeepWind analysis of the FLOWCON report (Jan 2026). Simulation reveals a “10-day delay” per typhoon evacuation and chronic port congestion. We examine the 26-day vs. 19-day construction scenarios and the critical need for “Port Integrators” to meet Japan’s 15GW target.
