In today's interconnected world, more and more Japanese businesses are taking the opportunity to expand their reach globally. But no matter where customers are in the world, all of them prioritize punctual and fast shipping.

How to choose the right international shipping option
Consider these key factors to help you decide between international shipping options:
Speed
For fast shipping, international express delivery services are the clear choice. If your shipments are time-sensitive, features like guaranteed delivery windows and real-time tracking can offer peace of mind. Consider how crucial speed is to your customers and your business operations.
Cost
Always do a cost comparison between your international shipping options. While express delivery services might be faster, international postal services offer economical rates that might be more feasible for your business. Balance your budget with the need for timely and secure delivery.
Weight and cargo volume
Different carriers specialize in different types of shipments. International postal services typically only handle lightweight parcels, whilst express delivery services can be equipped for larger, heavier cargo or odd-shaped packages. Assess the typical weight and volume of your shipments to ensure you choose a service that can efficiently handle your goods.
Specialty zones
Many carriers have particular strengths in certain regions. Some may have extensive networks within specific countries or continents, leading to faster and more reliable service in those areas. Consider where your primary customer base is located and choose a carrier with a strong presence in those regions.
Risk of loss or damage
Risk is always present when shipping internationally. Reliable international courier services offer robust tracking, secure handling procedures, and insurance options to mitigate the risk of loss or damage. Consider the value of your goods and the potential impact of loss or damage on your business. For high-value items, it’s always recommended to go with express delivery services for better protection.
Customer service
Responsive and helpful customer service is vital, especially when dealing with international shipments. Choose a carrier that offers 24/7 support and has a reputation for resolving issues quickly and efficiently. Consider the ease of communication and the availability of support in your local language.
