Business
Daiun Co., Ltd. is a long-established port transportation company founded in 1945, listed on the Standard Market of the Tokyo Stock Exchange. With bases in Osaka, Kobe, Nagoya, and Tokyo, the company provides an integrated offering of port cargo handling (unrestricted), customs brokerage, warehousing, international marine container transportation, NVOCC, and 3PL services. Its main customers are shipping companies, cargo owners, and prime contractor port transportation operators, and it handles the entire process of export and import cargo from loading and unloading to inland transportation and storage on an integrated basis. The Port Transportation Business accounts for 98.1% of net sales, complemented by the Motor Transportation Business (marine container inland transportation and ferry transportation) and the Non-Life Insurance Agency Business.
Business Model
The company undertakes port cargo handling, customs brokerage, warehousing, and inland transportation on an integrated basis for shippers and shipping companies, earning service revenue based on the volume of work performed. Building on continuous business relationships with key clients, it accumulates revenue through both acquiring new customers and deepening transactions with existing customers. By leveraging its overseas partner network through its China office, it aims to enhance the added value of International Marine Container Inland Transportation and thereby improve profitability.
Company Strengths
As an unrestricted operator under the Port Transportation Business Act, the company is able to handle integrated operations from cargo loading to unloading. It has locations in the major port cities of Osaka, Kobe, Nagoya, and Tokyo, and possesses a customer base and operational track record accumulated over 80 years since its founding in 1945. These form unique entry barriers that competitors cannot easily replicate in a short period.
The company has a system in place to complete port cargo handling, Customs Brokerage Business, Warehousing Business, NVOCC, and International Marine Container Inland Transportation entirely within its own group. In FY2026 (ending March 2026), operating revenue from the Port Transportation Business reached ¥9,044 million (up 6.8% year on year), and the ability to provide integrated services has led to continued orders from major clients.
As of the end of FY2026 (ending March 2026), net assets stood at ¥4,077 million, and cash flow from operating activities was ¥543 million (a significant increase from ¥216 million in the previous fiscal year). The fiscal year-end balance of cash and cash equivalents was secured at ¥1,498 million. The company continues to strengthen its financial position while repaying long-term borrowings, maintaining financial resilience against changes in the external environment.
ENVALITH's Perspective
Performance Trend
Over the past five fiscal years, operating revenue has fluctuated in the range of ¥8,092 million to ¥9,212 million. After a temporary decline in FY2024 (ending March 2024), revenue increased for two consecutive fiscal years, reaching ¥8,672 million in FY2025 (ending March 2025) and ¥9,212 million in FY2026 (ending March 2026). Operating income bottomed out at ¥164 million in FY2023 (ending March 2023) and has continued on a recovery trend since, reaching ¥347 million in FY2026 (ending March 2026), surpassing the FY2022 (ending March 2022) level of ¥326 million. As an external factor, the yen depreciation environment has supported orders for imported cargo, and steady order intake from major client companies has driven revenue growth. The company's forecast for FY2027 (ending March 2027) calls for operating revenue of ¥9,400 million and operating income of ¥350 million, projecting continued profit growth, but risks to the downside remain, including rising crude oil prices due to the situations in Ukraine and the Middle East and increased business costs from persistently high prices.
Growth Strategy
Growth in high-value-added SCM through new customer acquisition, deepening of existing customer relationships, and expansion of international through transport
Simultaneously advancing the development of new customers and the expansion of transaction volume with existing customers. In FY2026 (ending March 2026), net sales to external customers in the Port Transportation Business expanded by +6.8% year on year to ¥9,044 million, with the effects of these initiatives reflected in the figures.
Promoting expansion of orders for the integrated international multimodal through transport service, which combines import/export, coastal shipping, port cargo handling, warehousing, and inland transportation. Orders for imported cargo have remained solid amid the weak yen environment, contributing to revenue growth in FY2026 (ending March 2026).
Promoting the construction of SCM (Supply Chain Management) aimed at high value-added, high profitability, along with operational efficiency improvements. The operating margin for FY2026 (ending March 2026) improved to 3.8% (from 2.8% in the previous period), but the absolute level remains low, requiring continued efforts.
Fixed trade receivables, which stood at ¥214 million at the end of the previous fiscal year, fell to zero at the end of FY2026 (ending March 2026), with the allowance for doubtful accounts also declining significantly. This progress in strengthening the balance sheet also contributed to a substantial improvement in operating cash flow (¥543 million).
