Sourcing Agent vs. Trading Company vs. Going Direct: What Actually Differs

Trading company (sōgō shōsha)

Japan’s large trading companies — and the smaller specialist trading houses modeled on them — can source almost any product category through their own supplier networks, handle the transaction and paperwork, and take on inventory risk in ways a manufacturer usually won’t. The trade-off is a built-in margin that’s rarely itemized separately from the product price, and less visibility into which factory actually made your product or what it would cost to buy from them directly. This path fits best when you need a very wide range of products from one relationship and transaction simplicity matters more than unit cost.

Going direct

Approaching manufacturers yourself gives you full visibility into pricing and a direct relationship with the people actually making your product — no intermediary margin, and no one else’s priorities between you and the factory. The cost is your own time: writing RFQs that get answered (see the RFQ guide), following up in a way that doesn’t stall, and vetting a company you can’t easily visit (see vetting suppliers remotely) — all without necessarily speaking Japanese or knowing which follow-up cadence is normal versus a bad sign. This fits best when you already have Japan experience, a long-term relationship in mind, or enough volume that the time investment pays for itself.

A sourcing agent

An agent sits between the two: they run RFQ preparation, candidate identification, and Japanese-language outreach and follow-up on your behalf, and can stay on as your Japan-side contact once you’re buying — samples, schedule and spec changes, repeat orders. You still buy directly from the manufacturer: the agent doesn’t take title to the goods or mark up the product price the way a trading company does. You’re paying for the language and process work, usually as a fee for time spent, not for inventory or transaction risk being absorbed on your behalf. This fits best when you need several suppliers approached in parallel, or a supplier relationship run in Japanese, without hiring for it.

Which one, when

• Wide product range, one relationship, simplicity over unit cost → trading company
• Established Japan relationships, high volume, or in-house Japanese-speaking staff → direct
• New to Japan sourcing, need language and follow-up handled, want full price visibility → sourcing agent

These aren’t mutually exclusive over time. Some buyers use an agent to find and qualify a supplier and then run the relationship themselves; others keep the agent as their contact window because the day-to-day communication still needs to happen in Japanese. Either way, the supplier relationship is yours — what changes is who carries the correspondence. See managing a Japanese supplier after the first order for what that ongoing work involves.
