If you are an enterprise technology vendor considering Japan, you will likely have heard that it is a partner-driven market. For most vendors, the first route in is a reseller or distributor agreement, well before any commitment to a local entity. This article explains Japan's partner ecosystem: how the tiers are structured, how distributors, resellers and SIers differ, the main players in each, and the market nuances that are easy to miss if you have not done it before. It draws on Japanese trade press and our own tracking of market entry signals.

Partner-led selling is more embedded than in most markets, and the route to an enterprise buyer usually passes through two or three companies before it reaches the customer. As an example, Box Japan was established in 2013 and for most of its first decade sold only through partners, adding direct sales alongside them in more recent years.

The map

The basic flow is vendor, distributor, SIer or reseller, end customer. Distributors come in two types. Broadline distributors carry thousands of brands across hardware, software and cloud, and compete on reach and volume. Value-added distributors carry a narrower, specialist range, mostly security, infrastructure and data, and add their own engineering, support and localisation. Each tier reaches a different set of buyers.

Distributors: broadline and value-added

Japanese distributors buy from the vendor and sell to resellers and SIers rather than to end customers. They carry credit, contracts and often first-line support. The useful distinction is between broadline distributors and value-added distributors.

Broadline distributors. DIS (Daiwabo Information System) works with around 19,000 reseller partners from 96 locations across Japan, and SB C&S with around 15,000. Their strength is reach outside Tokyo and into mid-sized companies that a foreign vendor will never call directly. The trade-off is attention: a broadline catalogue runs to thousands of brands, and its sales teams move what resellers already ask for. Vendors with broad appeal often work with more than one. Arista Networks, for example, signed SB C&S in March 2026 and added DIS in September 2026.

Value-added distributors. Macnica, Networld, Tokyo Electron Device, Terilogy, SIOS and Assist employ engineers who learn a product well enough to support it in Japanese before the vendor has local engineers of its own. This is where many foreign security, infrastructure and data vendors start. Recent examples include Macnica with Unstructured (March 2026) and Prophet Security (August 2026), Tokyo Electron Device with Vanta (September 2026), Terilogy with Delinea (August 2026), Networld with Cloudflare (March 2026) and Halcyon (October 2026), and SIOS with Couchbase (November 2025) and PagerDuty (January 2026). Value-added distributors usually reach enterprise accounts through the SIers they supply.

CrowdStrike is an example of how the two types of distributor work together. Its Japan entity was formed in 2017, and from 2018 it sold through Macnica, mainly into enterprise endpoint security. In 2022 it added Networld as a second distributor to reach mid-sized, smaller and regional companies through Networld's nationwide reseller base, where the CrowdStrike name was still largely unknown. Networld also took on Japanese-language technical support as CrowdStrike's first support partner anywhere.

SIers

System integrators hold the largest enterprise and public sector relationships in Japan. A large SIer typically acts as prime contractor and passes much of the delivery down through layers of subcontractors. For a vendor, this means the customer often buys your product as part of an SIer's project, specified by the SIer's architects and supplied through a distributor.

SIers fall into a few families: those affiliated with hardware makers (Fujitsu, NEC, Hitachi), those owned by trading houses (CTC with Itochu, SCSK with Sumitomo, Marubeni I&C), those spun out of large user companies, and NTT Data. Several now sign vendors directly, sometimes as first agent in Japan. For example, CTCSP signed Cyberhaven in January 2026 with a stated target of 1 billion yen over five years, and Hitachi Solutions took on Radware's cloud DDoS service in November 2025.

An SIer agreement gives you named accounts and a delivery partner. The SIer will only bring your product into projects where it fits their architecture and their margin, so the work is in getting onto their reference designs, not just their price list.

Resellers, cloud integrators and MSSPs

Below the SIers sits a wide band of resellers, from national dealers to regional IT companies, alongside cloud integrators and managed security providers. Cloud integrators matter more each year. Anthropic's Claude, for example, has been resold in Japan since early 2026 through CTC, Classmethod, BeeX, NHN Techorus and Assist, each via AWS.

MSSPs wrap a product into a managed service, which is often how a mid-sized Japanese company prefers to buy security. NTT Security Japan, for example, signed KnowBe4 in April 2026, with NTT Docomo Business as a secondary reseller, and Arctic Wolf in May 2026.

The marketplace layer

All three hyperscalers run marketplaces, and all three now let Japanese partners sit in the transaction rather than bypassing them. The difference is how far each has gone with distributors.

AWS Marketplace is the most established in Japan. It has grown quickly since product listings became available in Japanese in 2025, and counts more than 6,000 ISVs and 2,500 channel partners. Under the original CPPO model, each reseller had to sign separately with each ISV, which held take-up back. The DSOR model now lets a distributor sit between the vendor and AWS resellers, matching the two-tier flow Japanese buyers already use. Networld was the first Japanese distributor approved, in June 2025, and SB C&S followed in November 2025. PagerDuty, for example, signed SB C&S as its first Japanese distributor in July 2026 and launched on AWS Marketplace at the same time.

Microsoft Marketplace opened multiparty private offers to Japan in July 2026, allowing a vendor, distributor and reseller to share one deal. Networld launched a partner programme the same day, and SB C&S followed in September 2026 with a two-tier model. Purchases can count toward a customer's Azure consumption commitment, which matters to the many Japanese enterprises standardised on Microsoft.

Google Cloud Marketplace supports channel private offers, which let a Japanese reseller sell a third-party product on a single yen invoice. Distributor activity here is lighter so far; Google Cloud partners such as G-gen offer it to their own customers.

SB C&S has said it intends to cover all three, because each ISV aligns with a different cloud. For a vendor whose customers are drawing down committed cloud spend, the marketplace that matches your own platform is now a route worth planning for from the start.

Choosing a partner

Portfolio or focus. A large value-added distributor brings credibility, engineers and a reseller base that takes its recommendations seriously. It also carries your competitors, and your product competes for the same engineers' time. A smaller specialist gives you a larger share of its attention but narrower reach. The question is whether your first year needs credibility in enterprise accounts or breadth across the market.

First in Japan. Many announcements describe a vendor's 国内初 (first in Japan) distributor. Examples between December 2025 and October 2026 include SB C&S with Zenity, Cognition and Simbian, TD SYNNEX with AccuKnox, and Macnica with Unstructured. Being first matters to the distributor because it defines the category and builds the support practice. That gives you leverage in the negotiation, but a distributor that invests in being first will expect a period of protection in return.

Exclusivity. Sole distribution (総代理店) is still common. DIS, for example, signed an exclusive with ZeroTrusted.ai in January 2026, and Assist renewed its sole distribution of NOREN for five years in September 2026. Exclusivity buys commitment: trained engineers, funded marketing, the product placed in front of resellers. It also ties your coverage to one company's customer base. A time-limited exclusive tied to targets is easier to live with than an open-ended one.

Adding a second. The most common pattern we see is one partner to establish the product and a second to widen reach. Examples include CrowdStrike with Macnica in 2018 then Networld in 2022, Arista with SB C&S then DIS in 2026, and PagerDuty with SIOS as reseller then SB C&S as distributor, also in 2026. Allow for this in the first agreement rather than renegotiating later.

Getting airtime

Signing is the easy part. A distributor's sales team sells what is easiest to sell, and a reseller's account manager proposes what the customer has already heard of. A partner-business specialist interviewed by Coral Capital puts the time to build a working reseller channel in Japan at two to three years, and warns against signing partners who never actually sell.

What we see working:

  • A named person on the distributor. Someone who speaks Japanese, attends their internal sales meetings and answers technical questions the same day. A partner manager covering Japan from Singapore or Sydney rarely gets that time.
  • Their engineers first. In the value-added tier, the distributor's engineers decide what gets recommended. If they can demonstrate your product with confidence, their sales team follows.
  • Easy to quote. When Networld took on CrowdStrike, it stressed giving resellers transfer and annual support pricing immediately. Japanese price lists, clear partner discounts and standard terms remove a reason to choose someone else.
  • Deals brought to them. Nothing raises your priority faster than registered opportunities from your own direct or regional activity flowing through the distributor.
  • Presence where resellers learn. SB C&S brought 20 network and security vendors to a single partner event in 2025. Those sessions are where categories are explained to the people who will sell them.
  • The Japanese calendar. Most enterprise budgets close in March, and next year's plans are set in the autumn. A vendor asking for pipeline in January is late.
  • Local proof. Case studies from Japanese customers carry more weight than global logos, and one is worth more than a translated deck.

When the entity changes things

A Japanese entity remains the turning point. It tells distributors, SIers and buyers that the vendor will still be here in five years, and it brings Japanese contracts, local support and a country manager who can sit in front of a customer's executives. Cognition, for example, signed SB C&S as its first distributor in March 2026, set up its Japan entity in April 2026, and added CTC as a reseller the same month. Saviynt took a different route, forming Saviynt Japan in June 2026 as a joint venture in which Assist holds 35%.

The entity rarely replaces the channel. It usually means more partners, managed more deliberately: a partner team that runs distributors and SIers, and a direct team that pursues named accounts and brings the channel into them. The vendors we see do this well built the channel before the entity, and hired the people to run it early rather than after the first year.

If you are weighing a first distributor agreement in Japan, or the first hires to run one, we are happy to share what we are seeing.
