What Hummingbird Solar does

Hummingbird Solar (ハチドリ電力, Hachidori Denryoku) is a Japanese private renewable energy electricity retail brand established in 2021 and operated by Borderless Japan Co., Ltd. (株式会社ボーダレス・ジャパン) as part of the Borderless Group portfolio of social-purpose businesses. The company supplies 100% renewable-energy electricity with a stated CO2 emission coefficient of zero to residential and corporate customers across 46 of Japan's 47 prefectures (excluding Okinawa and certain remote islands), partnering with regional general transmission/distribution utilities for grid access and physical delivery. Its core product is the HACHIDORI PLAN, a subscription-based electricity supply service offered via market-linked and fixed pricing tiers for households and dedicated low- and high-voltage plans for businesses.

The business model combines a direct-to-consumer online channel — a 5-minute self-serve switching flow with no cancellation fees and incumbent-utility handling by Hummingbird Solar — with a separate sales-led corporate motion, all delivered through a digital-only customer acquisition and management stack (web, CRM portal, LINE, email). Differentiating the brand from commodity retailers is the "1% for Social" mechanism, which routes 1% of each electricity bill to a rotating set of non-profits (covering children's welfare, gender equality/LGBT, disability/welfare, environmental protection, and other causes). Supporting modules include HACHIDORI ACADEMY community learning, a LINE-based consultation desk ("Hummingbird Consultation Room"), a public billing simulator, and an affiliate-marketed rooftop solar installation service via partner Solar Life.

As of February 27, 2026, Hummingbird Solar reported 7,151 household customers and 1,873 corporate customers spanning diverse industries (regional banks, IT services, forestry, sustainable tourism, agriculture, child welfare, waste management, temples, and regional revitalization). Management lists 田口一成 (Taguchi Kazunari) as business representative and 池田 将太 (Ikeda Shota) as representative of operator Borderless Services. Revenue is not publicly disclosed, no external equity funding rounds are reported, and the company has stated an aggregate 2030 target of 1.98 million residential and 128,000 corporate customers — an aggressive scale-up trajectory that current customer-count data does not yet confirm.
