TRUNK

What TRUNK does

TRUNK Inc. (株式会社トランク) is a Tokyo-based private company founded in October 2014 that operates an asset-light, sharing-economy cloud logistics and storage platform. Its core technology is a centralized cloud logistics system that connects end customers, third-party logistics providers, and storage facilities without TRUNK owning any trucks, warehouses, or inventory. A patent application for this sharing-based cloud logistics architecture was filed in March 2018. The company runs three primary product lines: CARAETO (a consumer-facing home delivery storage subscription priced at ¥500 per box per month, with nationwide courier pickup and app/PC ordering), TRUNK X (a B2B cloud logistics system serving apparel brands such as Mizuno, e-commerce companies, and property managers including Haseko Group), and Furima Hikkoshi (a 2019-launched service built with Rakuma and HiMOVE that lets users list items stored in CARAETO directly on the Rakuma flea market during relocation). Earlier consumer feature additions include Item Warp (2017-01, instant transfer of stored items between users) and Trunk Market (2017-04, a searchable directory of stored items).

TRUNK generates revenue through three models: a recurring ¥500/box/month subscription for CARAETO, per-transaction logistics fees for TRUNK X, and marketplace transaction fees on Furima Hikkoshi sales routed through Rakuma. Consumer services are sold via self-serve mobile app and web, with marketing driven by earned media coverage in major Japanese outlets (Nikkei, TV Tokyo WBS, AbemaTV, Oggi.jp) and extensive distribution partnerships spanning telco (NTT DOCOMO), utilities (Osaka Gas, Nichigas), property management (Haseko, JBR), retail (Yodobashi Camera, Matsutake Ginza), and loyalty programs (Times Club, JAL Card). B2B services are sold directly to enterprise customers. Operations are concentrated in the Tokyo metropolitan area. The company is privately held and venture-backed, with disclosed funding totaling approximately ¥1.0–1.1 billion across rounds from Mitsubishi UFJ Capital, Mizuho Capital, NTT DOCOMO Ventures, en-Japan, Haseko, SBS Holdings, aucfan, NEC Capital Solutions, Seibu Shinkin Capital, and Tokyu Fudosan between 2016 and 2021. CEO and founder Hayato Matsuzaki leads the company, which has 11–50 employees.

Scale indicators3 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• MakeSpace: US-based on-demand delivery-storage service (consumer segment). Closest international reference point for the CARAETO consumer business model and a useful benchmark for subscription storage unit economics outside Japan.
• Shipbob: US-based fulfillment-as-a-service provider for SMB and DTC e-commerce brands. Demonstrates the global business model that TRUNK X is targeting for apparel/retail customers — outsourced delivery, storage, and inventory without owning infrastructure.

Broad incumbents

• Yamato Holdings: Japan's largest door-to-door parcel carrier (TA-Q-BIN brand). A potential competitor in either consumer storage or B2B cloud logistics, with unmatched operational depth and brand recognition that could displace asset-light entrants.
• Nippon Express: Major Japanese logistics provider offering warehousing, contract logistics, and transportation. Most directly comparable to TRUNK X (B2B contract logistics) given its established warehousing footprint, and the most likely large-player entrant into apparel/retail cloud logistics.
• BUSSAN: Operates a logistics and storage business in Japan including delivery storage offerings for individuals. A broader incumbent that overlaps with both TRUNK's consumer storage and TRUNK X B2B logistics, though it is not exclusively focused on the sharing/cloud-logistics thesis.
• Sagawa Express: One of Japan's two dominant parcel-delivery carriers. Sagawa owns the nationwide courier infrastructure that TRUNK's asset-light model relies on, and could trivially launch a competing consumer-storage subscription at scale.

Direct peers

• Accrea / Accrea Storage (LIFULL): Japan-based delivery-on-demand storage service backed by LIFULL. Competes head-to-head with CARAETO for urban Japanese consumers who want box-pickup home storage without visiting a self-storage facility.
• Minikura (by artmore): A direct Japanese competitor in the box-based delivery-storage category. Minikura lets consumers ship items to a shared warehouse for monthly per-box storage and on-demand return — almost identical to TRUNK's CARAETO value proposition, and a benchmark for Japanese consumer storage pricing and unit economics.
• ShareQ (by Idea Lab): Japanese subscription storage product with on-demand retrieval and courier pickup. Targets the same consumer persona as CARAETO — urban residents seeking decluttering — making it a direct consumer-side competitive benchmark.

Others

• Rakuten (Rakuma): Operator of Rakuma, the Japanese flea-market app that TRUNK is integrated with via Furima Hikkoshi. Rakuma is more partner than competitor, but Rakuten's logistics ambitions (Rakuten EXPRESS) and broader commerce platform represent both a channel and an eventual vertical-integration threat.
