Ecoda Co.

What Ecoda Co. does

Ecoda Co. (株式会社ECODA) is a privately held Japanese solar installation specialist headquartered in Shibuya, Tokyo, with branch offices in Yokohama, Saitama, Chiba, and Nagoya. The company designs, procures, and installs residential solar PV systems, household storage batteries (家庭用蓄電池), and all-electric home equipment (IH cooktops, EcoCute water heaters), and it operates primarily under a direct-to-consumer model. Customer acquisition is concentrated on inbound channels: a free simulation and on-site pre-inspection process accessible via a 365-day toll-free consultation line (0120-065-776), the corporate website, an Instagram account (@ecoda_inc), a LINE official account, and an SEO-oriented content platform covering solar PV, batteries, power conditioners, FIT/post-FIT strategy, subsidies, maintenance, and end-of-life disposal. The company explicitly differentiates itself from general hardware stores and home centers by positioning as a specialist contractor with certified electricians and in-house installation teams.

ECODA's product offering is centered on two core SKUs - the 太陽光発電システム (solar PV system) and 家庭用蓄電池 (home storage battery) - sold either standalone or as combined bundles. Documented package price ranges are approximately ¥1.2-1.5M for a 5kW-class solar-only system, ¥2.7-3.1M for a 5kW solar + 10kWh battery package, and ¥3.5-4.2M for a full solar + battery + V2H package, with the company also assisting customers in applying for government and municipal subsidies. Underlying technology is conventional for the category: high-efficiency PV panels, power conditioning systems, home battery storage units, distribution-board modifications, grid interconnection, and a remote monitoring layer that supports real-time generation tracking and next-day emergency dispatch. The company also provides maintenance, periodic inspection, power-conditioner replacement, panel cleaning, and disposal/recycling guidance. Product warranties extend up to 30 years and installation work is covered for 10 years.

Commercially, ECODA reports an installation run rate exceeding 2,000 residential projects per year, which it leverages for direct manufacturer procurement without intermediate margins. The firm is registered as 株式会社ECODA in Japan, with stated registered capital of ¥30,000,000 and is led by Representative Director 平間一也 (Hirama Kazuya). It holds Tokyo Metropolitan Governor-issued electrical construction permits (許可 (般ー7) 第160515; 都第2512386号). There is no disclosed external equity, debt, venture, or institutional funding, and corporate ownership remains inside the operating entity; revenue, founding year, headcount, and detailed financial history are not provided in the input material, leaving those dimensions under-disclosed.
