Truck Okoku

What Truck Okoku does

Truck Okoku Co., Ltd. (株式会社トラックオーコク, formerly Nentrys Inc., rebranded August 2024) operates the "Truck Kingdom" (トラック王国) commercial vehicle online marketplace, founded in 2006 and headquartered in Shibuya, Tokyo with 182 employees as of December 2025. The core platform intermediates the buying and selling of trucks, buses, and heavy machinery across Japan, maintaining standing inventory of several thousand units and integrating with seven physical showroom locations for an omnichannel experience. Beyond core vehicle trading, the company has built an integrated ecosystem of sub-brands: Truck Kingdom Leaseback (sale-leaseback financing), Tenshoku (logistics/construction/manufacturing-specific job placement), Foreign Talent (Specified Skilled Worker visa introduction), and Parts Shop (e-commerce with approximately 4,000 SKUs). Revenue derives from marketplace transaction commissions, recurring leaseback fees, subscription/matching fees for job listings, parts e-commerce margins, and fixed-fee warranty products (¥50,000 entry fee, up to ¥1 million compensation).

The technology stack combines Byteplus generative AI and OpenAI ChatGPT to power two flagship AI products: AI Kumachan, a 24-hour digital-human customer service agent on TikTok and YouTube LIVE with reported single-day replay counts exceeding one million, and Megaphon, a LINE-based AI secretary featuring voice interface and OCR document scanning for logistics and construction operators. The go-to-market motion is multi-modal: a sales-led approach through seven regional showrooms, product-led growth via a free-tier website with over 3,000-vehicle comparison functionality and approximately 500,000 monthly visitors, event-driven leads from industry exhibitions such as Japan Truck Show 2026, and channel partnerships including the U-NEXT Pirates M-League sponsorship and a national weekly radio program.

The company is led by co-founder and CEO Kazuo Tsushima and Director Makoto Miyata, with CTO Katsura Shotaro appointed in June 2026 to lead AX/DX strategy. The company operates two wholly-owned subsidiaries (Route4 Inc. for HR services and 8Gear Inc. with a Tanzania presence) and is privately held with no disclosed institutional investors or revenue figures.

Direct peers

• ロジクエスト (LogiQuest): Logistics industry specialized recruitment and media platform in Japan. Directly comparable to Truck Okoku's Tenshoku (テン職) sub-brand in serving driver and logistics worker hiring demand.
• Proto Corporation (Goo-net / グーネット): Operates Goo-net, the largest Japanese used vehicle marketplace including trucks and commercial vehicles. Most directly comparable as a B2B-leaning online marketplace for used vehicles, with broader inventory but less specialization in commercial vehicles than Truck Okoku.
• Recruit Car Sensor (カーセンサー): Major Japanese used vehicle platform by Recruit, includes commercial vehicle listings and dealer network. Comparable in marketplace model and B2B service orientation, though with broader consumer focus and larger scale.

Others

• Auction sheet providers / TAA (Toyota Auto Auction): Physical auto auction infrastructure that feeds Japan's used vehicle supply chain. Adjacent to Truck Okoku's marketplace as a supply-side mechanism, not a direct competitor but ecosystem participant.
• SmartDrive: Fleet management SaaS provider for commercial vehicles in Japan, already a partner of Truck Okoku (SmartDrive Fleet integration). Comparable in serving logistics operators with technology services, complementary rather than competitive.
• Mercari (for C2C parallel): Major Japanese C2C marketplace with growing vehicle and commercial equipment categories. Adjacent in online marketplace mechanics and Japanese consumer reach, but not focused on commercial vehicles.

Broad incumbents

• Nexstage (ネクステージ): Large publicly listed used vehicle retailer handling passenger cars and light commercial vehicles. Comparable in physical showroom strategy and used vehicle intermediation, though more oriented to passenger vehicles.
• IDOM (Gulliver / ガリバー): Largest Japanese used car retailer with nationwide physical network. Overlaps with Truck Okoku in used vehicle retailing and physical showroom distribution, though focused primarily on passenger vehicles.

Regional players

• Tatsumi Corporation (辰巳商会): Used commercial vehicle dealer network in Japan with regional physical yards. Comparable in used truck intermediation and physical showroom model, though primarily regional rather than nationwide.

Emerging players

• Drive (formerly Vitalforce / バイタルフォース): Driver recruitment platform focused on trucking industry in Japan. Overlaps with Truck Okoku's HR services and faces the same '2024 problem' labor shortage opportunity.
