Open reference · METI FIT disclosure
Japan’s small-scale biomass projects, mapped.
日本の小規模バイオマス発電マップ（2MW以下）
This is an open, citable reference to woody biomass Japan projects and all other small-scale biomass at 2 MW and below, drawn from METI’s monthly FIT certification disclosure; this snapshot is 2026-05. A plant is shown as operating once it files an operation-start report, and as certified-but-not-operating when it holds FIT certification without one. Projects certified four or more years ago with no reported operation start are shown as stalled — many will never be built without a new developer.
Operating · 稼働中Certified (<4 yrs) · 認定済（4年未満） Certified 4+ yrs, not operating · 認定から4年以上・未稼働Locations shown at district (大字) level.
