Meijo Nano Carbon

What Meijo Nano Carbon does

Meijo Nano Carbon (株式会社 名城ナノカーボン) is a privately-held Japanese nanomaterials manufacturer founded in 2005 and headquartered in the Science Exchange Plaza in Moriyama ward, Nagoya, Aichi Prefecture. The company is incorporated as a Kabushiki Kaisha (stock corporation) and operates with a lean team of 11-50 employees under founder and Representative Director Tsuyoshi Hashimoto. Its singular focus is the production of single-walled carbon nanotubes (SWCNT) with high purity, high crystallinity, and controlled semiconducting properties — a category of advanced nanomaterial used in applications requiring strength, electrical conductivity, and semiconductor functionality.

The company's differentiation rests on four claimed "world's highest level" process technologies: synthesis, purification, separation, and dispersion of carbon nanotubes. These capabilities are positioned to enable consistent semiconducting-grade SWCNT output, which the company markets to a horizontal customer base across materials science and electronics industries. Pricing, revenue mechanics, and customer identity are not publicly disclosed; go-to-market is presumed to operate via direct B2B sales to industrial and research customers, primarily in Asia, with no public marketing or distribution channel information available.

The company raised a 2018 funding round from a consortium of Japanese institutional and venture investors including SMBC Venture Capital, SPARX Group, Shinsei Bank, Aichi Bank, Ogaki Kyoritsu Bank, Juroku Lease, Shizuoka Capital, and Nippon Venture Capital, with the amount undisclosed. In 2026, the company was named as one of six parties collaborating with Kansai Electric Power and Toyota on hydrogen supply, utilization, and infrastructure initiatives in Japan, suggesting potential expansion into the energy vertical. No AI capabilities, app products, public APIs, or geographic expansion beyond Asia are disclosed.

Direct peers

• Thomas Swan: UK-based specialty chemical manufacturer offering Elicarb CNT products. Direct peer as a smaller-scale, specialty-focused CNT producer serving research and industrial customers.
• OCSiAl: World's largest producer of single-walled carbon nanotubes (Tuball brand), headquartered in Luxembourg with global operations. Direct competitor in SWCNT manufacturing with a focus on high-volume commercial supply — overlapping in product category, customer base (electronics, composites, batteries), and technology positioning.
• Nanocyl: Belgian manufacturer of multi-walled carbon nanotubes serving energy storage, composites, and conductive plastics. Direct peer as a specialty CNT producer supplying industrial customers, though focused on MWCNT rather than SWCNT.
• Cnano Technology: US-listed Chinese manufacturer of multi-walled and few-walled carbon nanotubes serving lithium-ion batteries, conductive plastics, and composites. Comparable as a CNT raw-material supplier targeting industrial-scale applications, though with broader product portfolio and significantly larger scale.
• Hyperion Catalysis International: Pioneering US-based manufacturer of multi-walled carbon nanotubes serving plastics, electronics, and energy markets. Comparable as a specialist CNT producer with deep technical heritage.

Regional players

• JEIO (Jeollanam-do Institute of CNT): Korean regional institute-affiliated CNT producer focused on Asian industrial markets. Comparable as a regional Asian CNT manufacturer serving similar materials customers in Korea and Japan.

Broad incumbents

• Arkema: French specialty chemicals group with a Graphistrength CNT product line for composites, electronics, and energy applications. Comparable as a larger incumbent offering CNT-based materials as part of a broader industrial chemicals portfolio.
• LG Chem: Korean chemical major producing carbon nanotubes primarily for lithium-ion battery applications. Comparable in CNT manufacturing technology, particularly relevant as a regional Asian supplier competing in battery and electronics materials.
• Resonac (formerly Showa Denko): Japanese chemical and materials conglomerate producing VGCFTM carbon nanotubes for batteries, composites, and electronics. Comparable as a domestic Japanese CNT supplier with broader industrial materials portfolio — offering overlapping capability but at much larger corporate scale.
