About the FundedIQ Energy startup funding data in Japan

FundedIQ tracks announced startup funding rounds and organises them by company, funding date, stage, amount, industry, location and investor. The dataset is refreshed weekly, and new rounds are normalised and de-duplicated before they are published, so the same round reported twice on different dates is recorded once.

Rounds whose amount was not disclosed (5 of 10 in that period) are counted as rounds but excluded from capital totals and from the median. The most recent round on record for funded Energy startups in Japan is dated Jun 2026.

The table above shows the 10 most recently funded companies. Full funding histories, investor lists and founder contacts across the whole dataset open on a FundedIQ plan.
