Seino, formally Seino Transportation, is a major Japanese freight and logistics company known for its Kangaroo-branded transportation services. The Seino Group began as a trucking business in 1930 and is based in Ogaki, Gifu Prefecture. Its domestic network connects locations across Japan from Hokkaido to Okinawa and supports both business freight and smaller parcel deliveries.
Seino's domestic services cover several types of shipments. Kangaroo Tokkyu-Bin handles general freight, Kangaroo Mini-Bin is designed for smaller business shipments, and Kangaroo Courier Service handles eligible parcels addressed to individuals. The company also provides charter transportation, valuables transport, cash-on-delivery services, return logistics and specialized timed-delivery products.
For international logistics, Seino offers international transportation, Kangaroo International Courier Service, International AIR Pack, sea and air freight, international moving and Global 3PL solutions. Its confirmed operating presence for this page includes Japan, the United States, China, Mexico, India, Thailand, Vietnam, Indonesia, Malaysia, Germany, Italy and Austria. Seino also connects shipments with a much broader global logistics network, but partner-served destinations should not automatically be treated as countries where Seino itself operates.
Tracking is an important part of Seino's transportation services because shipments can range from ordinary domestic packages to commercial freight and international consignments. Customers can check delivery progress using the inquiry number assigned to the shipment, while business users have additional My Seino tools for managing and monitoring multiple consignments.
How to Track Seino packages
To Track a Seino package with 4Tracking, enter the shipment's inquiry or tracking number into the tracking field. 4Tracking can attempt to identify the carrier automatically, or you can manually select Seino when necessary. The package tracking page then displays the available Tracking events associated with the shipment.
Seino also provides an official delivery-status service on its website. After entering the inquiry number, customers can view the current delivery status and select a detailed view for additional pickup and delivery information when available.
How long does Seino keep Tracking information available?
Seino states that delivery status can be checked through its standard public Tracking service for shipments accepted within the previous two months. For older shipments, the company instructs customers to contact the nearest Seino sales office and provide the shipping date together with the inquiry number.
Business customers using some My Seino services may encounter different online history periods for specific tools, so the standard public Tracking page and account-based business services should not be assumed to have identical retention periods.
Seino tracking number formats
Seino provides a clear format for the inquiry number used by its standard delivery-status system. The number contains 10 digits when entered without hyphens. Seino also accepts the formatted version with hyphens, which contains 12 characters in total.
An official Seino inquiry form illustrates the format as 123-456-7890. This is a formatting example rather than a real package. When using the main Tracking page, the same type of number can be entered as the 10 digits without hyphens.
If your seller supplies several identifiers, look for the Seino inquiry number printed on the waybill or shipment information. An online-store order number is not necessarily the same as the carrier's Tracking number. Entering the actual Seino number gives package tracking systems the best chance of locating the shipment.
Seino delivery times
Seino does not publish one universal delivery time for every service and route. For ordinary domestic services, its website provides a transit-time search that calculates a general arrival date according to the shipping date and the relevant Seino sales offices. This is more reliable than applying one fixed number of days to all packages in Japan.
Seino does publish specific timing for several premium domestic services. Kangaroo Super 9 and Kangaroo Super 10 are designed to deliver eligible shipments by 9:00 or 10:00 the following morning. Availability depends on the service area, so these deadlines should not be applied to ordinary shipments.
Another supported example is Kangaroo SAVE Express. Seino states that eligible shipments addressed to businesses within an approximately 800-kilometer range can be delivered by the following morning. The company notes exceptions for islands and some other areas, and transportation can be delayed by severe weather, accidents or traffic conditions.
Kangaroo Business service is also designed for delivery to business addresses by the following morning, while Kangaroo Air Freight uses aircraft to provide next-day delivery to major cities across Japan. These are service-specific examples and do not represent the delivery schedule of every Seino package.
International transit times vary more widely because the selected air, sea, courier or multimodal service, customs clearance and destination handling all affect delivery. Seino's international service pages direct customers to the relevant international department for an estimate of the required transportation time rather than publishing one delivery range that covers every country.
How to contact Seino about shipment issues
If a domestic Seino package is delayed or has an unusual Tracking status, Seino provides an official delivery-inquiry form on its website. The form asks for the inquiry number together with the customer's contact information and details about the issue. Seino states that submitted inquiries are reviewed between 9:00 and 17:00.
For urgent domestic shipment questions, Seino recommends contacting the nearest sales office directly. Its official branch finder lets customers search by address, postal code or sales-office name. Using the office responsible for the shipment is preferable to relying on an unrelated general corporate telephone number.
For Kangaroo International Courier Service, Seino publishes dedicated regional contacts in Japan. The East Japan international department can be reached at 03-3851-2639, the Central Japan department at 052-671-9161 and the West Japan department at 06-6576-5327. These contacts handle matters such as international pickup requests, rates and required transit times.
When contacting Seino, keep the 10-digit inquiry number, shipping date, sender and recipient details and the latest Tracking event available. If the shipment was purchased through an online store, the sender may also need to participate because it arranged the transportation and holds the original shipping documents.
Frequently asked questions about Seino package tracking issues
How can I Track a Seino package on 4Tracking?
Enter the Seino inquiry number in the tracking field on 4Tracking. The system can attempt to identify Seino automatically, or you can select the carrier manually and view the available package tracking events.
What does a Seino tracking number look like?
For Seino's standard delivery-status service, the inquiry number contains 10 digits without hyphens. Seino also accepts a 12-character presentation containing the same digits separated by hyphens, such as the official format example 123-456-7890.
Why is my Seino tracking number not working?
Check that you entered the correct 10-digit inquiry number and did not accidentally use the merchant's order number. If the shipment was only recently accepted, Tracking information may not yet have been registered. If the problem continues, contact the sender or the Seino sales office responsible for the shipment.
How long can I Track a Seino shipment online?
Seino's standard public delivery-status service allows Tracking for up to two months after the company accepts the shipment. For an older shipment, contact the nearest Seino office with the shipping date and inquiry number.
How long does Seino delivery take in Japan?
There is no single transit time covering every domestic route. Seino provides an official transit-time search for ordinary shipments. Faster products have separate schedules, including Super 9 or Super 10 delivery by 9:00 or 10:00 the next morning on eligible routes and Air Freight next-day delivery to major cities.
What is Kangaroo SAVE Express?
Kangaroo SAVE Express is a timed service for eligible business-address shipments. Seino states that it can deliver goods traveling within approximately 800 kilometers by the following morning, subject to area restrictions and transportation conditions.
Why has my Seino Tracking stopped updating?
A package can travel between Seino facilities without generating a new public event at every stage. Weather, traffic, route schedules or transfer to an international logistics partner can also create gaps. Compare the latest Tracking event with the expected delivery date and contact the responsible Seino sales office if the shipment appears overdue.
Can I Track an international Seino package with the same number?
Use the shipment number supplied with the international consignment first. The exact Tracking process can depend on the international service and any logistics companies involved later in the route. If another carrier number is issued after a handoff, that identifier may provide additional information for the later stage.
Does Seino operate outside Japan?
Yes. The confirmed operating scope for this page includes Japan, the United States, China, Mexico, India, Thailand, Vietnam, Indonesia, Malaysia, Germany, Italy and Austria. Seino also provides international transportation through a larger global logistics network, but partner destinations are not necessarily Seino-operated markets.
Who should I contact if my Seino package is delayed?
For domestic deliveries, use Seino's official delivery-inquiry form or contact the nearest sales office, especially for urgent cases. For Kangaroo International Courier shipments arranged in Japan, Seino provides separate East, Central and West Japan international departments for shipment inquiries.
Can 4Tracking change the delivery address or investigate a Seino claim?
No. 4Tracking provides package tracking information but does not transport Seino shipments or control delivery. Address changes, shipment investigations, damage reports and other operational requests must be handled by Seino, the sender or another carrier responsible for the relevant stage of transportation.
