FANUC, maker of the familiar "yellow robots," and Yaskawa Electric, which built the world's first all-electric industrial robot. FANUC leads on revenue, Yaskawa on headcount. From company history and five years of results to a comparison of CNC and servo/inverter businesses, "MOTOMAN NEXT" — an autonomous robot with a built-in NVIDIA GPU — facilities, and mid-term plans.
Canon has held the

Tokyo Electron's revenue runs about 4x SCREEN Holdings'. A comparison of breadth versus depth — Tokyo Electron spans deposition, etching, and cleaning, while SCREEN holds a 34.7% world share concentrated in cleaning equipment alone — covering company history, five years of financial results, product lineups, facilities, and mid-term plans.
From EV batteries to data-center energy storage to defense and space applications, batteries are a growth field that Japan's electrical-equipment and electronic-components makers are throwing everything at — yet their origins and strategies couldn't be more different. Panasonic Energy absorbed Sanyo Electric's battery business; GS Yuasa traces back to a lead-acid battery pioneer founded in 1895; Murata Manufacturing entered the field in 2017 by acquiring Sony's battery business. This article compares all three companies' histories, financial results, products, facilities, and outlook.
Shin-Etsu Chemical holds a leading global position in semiconductor-grade silicon wafers, while Toray develops carbon fiber and composite materials. Comparing the two companies' materials portfolios, results, and technical strategies.
Nippon Steel completed its acquisition of US Steel in June 2026, putting it among the world's top crude steel producers, while JFE Holdings holds the
NSK is Japan's #1 and roughly the world's #3 bearing maker; NTN is Japan's #2 and the world's #1 in constant-velocity joints. In May 2026 the two companies reached a basic agreement to integrate under a joint holding company. This piece reads through why two domestic leaders would join forces in the bearing industry that underpins every rotating part in automobiles, industrial machinery, machine tools, and robots — comparing company scale, products, and technology strategy before getting into what the integration actually involves.
DMG Mori and Okuma are public and disclose results; Yamazaki Mazak is private and discloses none. Comparing company history, financial trends over time, OSP (Okuma's self-developed CNC) against Yamazaki Mazak's strength in multi-tasking machines, facilities, and mid-term plans — including what the disclosure gap itself says about the industry.
Toyota, founded in 1937; Honda, established in 1948; and Nissan, born out of a merger of several companies — comparing all three companies' histories, five years of financial results, production-network restructuring, FY2026/3's sharply divergent results (Toyota becoming the first Japanese company ever to top ¥50 trillion in revenue, Honda falling into an operating loss on EV-related charges, Nissan mid-restructuring and cutting roughly 20,000 jobs), and their race to commercialize solid-state batteries.
Kubota runs 2.5-3x Yanmar's revenue. From company history and a five-year scale comparison, to a large-tractor and combine-harvester spec showdown, autonomous driving technology, domestic facility footprints, and both companies' mid-term management plans.
Japan's
Japan's largest, Mitsubishi Heavy Industries; the most diversified, Kawasaki Heavy Industries; and IHI, strong in aircraft engines. From revenue scale to a world-leading gas turbine, a head-on rivalry in submarine construction, and how each company's mid-term plan responds to rising defense spending and a recovering aviation market.
TEPCO Holdings leads on revenue; Kansai Electric leads on nuclear power. A comparison of two very different places in the nuclear-restart story — TEPCO restarting its first reactor since the Fukushima accident in April 2026, against Kansai Electric, which already has 4 of its 7 reactors running.
Tokyo Gas serves the greater Tokyo region, Osaka Gas (Daigas Group) the Kansai region. From an 1885 founding tied to Shibusawa Eiichi versus an 1897 founding, through five years of earnings, LNG procurement and overseas energy, electricity retail and non-gas businesses, to the "methanation" race both companies are running to decarbonize city gas, plus a map of their development and manufacturing sites.
NTT traces back to the 1985 privatization of Japan's public telecom monopoly; KDDI's roots run through DDI, founded in 1984; SoftBank pivoted from software distribution into a carrier through M&A. Comparing all three companies' five-year financial results, mobile subscriber share, AI/data-center investment, and their divergent technology bets on "what comes after radio" — NTT's optical-network vision IOWN, KDDI's Starlink partnership, and SoftBank's HAPS.
JR East, posting record revenue for a fifth straight year, and JR Central, carrying the enormous Chuo Shinkansen maglev project. From a five-year scale comparison to the next-generation "E10 series" versus the Chuo Shinkansen maglev, a look at IC-card payment infrastructure (Suica vs. TOICA), and a map of both companies' development and manufacturing facilities.
Kajima, the first Japanese contractor to top ¥3 trillion in revenue; Taisei, which posted record profit; Shimizu, which bounced back from its first-ever operating loss to post two straight years of profit growth. Comparing all three companies' founding years (1804-1873), five years of financial results, frontier businesses from overseas construction to space development, and construction robotics.
Mitsubishi Electric's total company revenue is larger, but Daikin leads the world in air conditioning alone. Comparing the inverter air-conditioning technology Daikin spread worldwide against Mitsubishi Electric's "Kirigamine" line, differentiated by its own infrared sensor, "Move Eye."
ispace (lunar transport), Synspective (small SAR satellite constellations), and Astroscale (on-orbit servicing / debris removal) — three Japan-born "NewSpace" companies, all listed on the Tokyo Stock Exchange Growth Market, compared across history, five fiscal years of results, products, technology strategy, facilities, and mid-term strategy. All three carry massive operating losses, yet each is capturing government and defense demand through a distinct path to viability.
