Exeno Yamamizu

What Exeno Yamamizu does

Exeno Yamamizu Corporation (株式会社エクセノヤマミズ) is a privately held Japanese maritime services company founded in 1947 and headquartered in Chiyoda-ku, Tokyo. It provides a one-stop portfolio of ship and marine transportation services organized around seven specialized departments: grain transportation cargo brokerage (handling approximately 30% of Japan's soybean, corn, wheat, and canola import volume), chartering brokering for Handy/Handymax and Panamax/Cape dry bulk vessels, sale-and-purchase (S&P) brokerage of secondhand ships (averaging ~20 vessels per year, ranging from Japanese coasters to VLCCs), maritime registration and documentation services for foreign flag vessels, marine machinery and chemical product sales, marine fuel and lubricant supply across hundreds of global ports, and LNG carrier brokerage.

The company monetizes primarily through transaction fees on successful fixtures and S&P closings, complemented by hardware sales (deck washing machines, gas-free fans, plate cleaners), professional services (vessel registration, valuation), and managed services (ship owning and operations consignment). Major institutional shareholders NYK Line (15.0%) and Mitsui O.S.K. Lines (12.5%) provide strategic credibility; wholly-owned subsidiaries Yamamizu Shipping Co., Ltd. and Honda Heavy Industries Co., Ltd. extend post-fixture, ship management, and ship design capabilities.

Underlying technology assets include the proprietary YAMAMIZU Index — the exclusive Baltic Exchange spot freight benchmark for US Gulf-to-Japan Supramax/Ultramax dry bulk grain, published weekly — and a marine chemical product line (YCC disinfectants and plate cleaners) developed over decades for tank cleaning and environmental protection. Distribution is exclusively direct enterprise sales through dedicated department phone lines and email channels, supplemented by membership in Japanese maritime industry associations and overseas sales service in Singapore.

Direct peers

• Simpson Spence Young (SSY): Leading independent global shipbroker covering tankers, dry cargo and S&P. Directly comparable to Exeno across chartering and secondhand ship transactions; competes for the same Japanese charterer flow.
• Howe Robinson Partners: Independent shipbroker specializing in dry cargo chartering and ship sale & purchase. Closely overlaps Exeno's Handy/Handymax, Panamax/Cape and S&P departments in target customer base.
• Maersk Broker: Shipbroker affiliated with the Maersk group, offering dry cargo, tanker and S&P services globally. Comparable chartering and S&P footprint; competes for the same pool of Japanese and Asian charterer clients.
• Clarkson PLC: World's largest shipbroker and shipping research house, offering chartering, S&P, offshore and financial services globally. Direct competitor across every service line Exeno Yamamizu offers, but with vastly greater scale, public-market data transparency and global coverage.
• Fearnleys: Norwegian-headquartered shipbroker with deep dry bulk, tanker and offshore capabilities. Closest European comparable to Exeno's chartering and S&P business, with similar mix of freight research and broker services.
• Braemar ACM: Shipbroking and maritime services group with strength in tankers, dry cargo, S&P and offshore. Comparable product mix to Exeno's broking and technical services, with a publicly listed parent.
• Eastbrokers International: Japan-incorporated, Greek-affiliated shipbroker active in dry bulk chartering and S&P. Direct head-to-head competitor for Japanese tonnage and chartering mandates.

Broad incumbents

• Mitsui O.S.K. Lines (MOL): Major Japanese shipping conglomerate holding 12.5% of Exeno Yamamizu and co-founder of e5 Lab. Overlaps as tonnage provider and customer but is a broad-based global carrier, not a niche shipbroker.
• NYK Line (Nippon Yusen Kaisha): One of Japan's largest shipping conglomerates and a 15.0% strategic shareholder of Exeno Yamamizu. Overlaps as both customer (charterer/owner) and counterparty in e5, but operates at vastly broader scale across containers, dry bulk, tankers and LNG.
• K Line (Kawasaki Kisen Kaisha): Japanese shipping major with dry bulk, car carrier, energy and container exposure. Comparable Japanese customer base and a potential counterparty for Exeno's chartering and S&P services, but operates at carrier rather than broker scale.
