Reachable Buyer Map

Prepared for Ushin Rai · QBurst · August 2026
Japan is the market where the buyer is easy to name and hard to reach. The decision is written up and circulated rather than made in the room, the incumbent is often a systems integrator with a thirty year relationship, and the useful introduction usually has to come from inside. This page sets out where the engineering and AI budget actually sits in Japan, who signs, and roughly how many companies are in each group. It describes the market rather than your business, and there is nothing to buy at the end of it.
Companies above the SME line
Japan's corporate base is roughly 3.6 million companies, and about 99.7 percent of them are small or medium by the official definition. The layer above that line is where an outside engineering partner is a budget decision rather than a leap of faith, and it is small enough to hold as one named list.
Who signs: chief information officer, the head of the information systems department, the DX officer, head of digital, and the corporate planning lead who actually owns the budget line.
10,000 to 12,000
companies sitting above Japan's official SME threshold, out of roughly 3.6 million companies in total
Listed companies
The group under the most public pressure to show digital progress, because the disclosure regime asks for it and the market reads the answer. That pressure produces named, dated buying windows rather than vague intent, and it puts a deadline on work that would otherwise drift.
Who signs: chief digital officer, the executive officer for DX, head of information systems, and the corporate planning lead who faces investors.
3,800 to 4,000
companies listed across the exchange's three market segments, of which roughly 1,600 sit in the top segment
Regional banks and credit associations
The most enumerable buyer group in the country and one of the least worked by engineering partners. Every institution is named, licensed and published, they run comparable core systems, and what one of them buys the next twenty will look at closely. Long cycles, and durable once landed.
Who signs: head of systems planning, head of digital strategy, the executive officer for operations, and at the smaller institutions, the president.
95 to 100 regional banks
plus roughly 250 to 260 credit associations, every one of them named in the financial supervisor's published list
Foreign-affiliated companies operating in Japan
The shortest cultural distance for an outside engineering partner, because the buying language is often English and the parent already works with vendors it has never met in person. Stated plainly: this group is surveyed rather than registered, so it is assembled from filings, hiring and local entity records rather than pulled from a list.
Who signs: country manager, IT director for Japan, the regional chief technology officer, and the head of shared services at the parent.
Surveyed, not registered
the annual government survey reaches a few thousand firms, and a survey is a sample rather than a register, so this segment is described rather than counted
The systems integrator layer
Most of Japan's enterprise IT budget flows through integrators rather than direct to engineering vendors, which makes the direct approach and the partner approach two separate motions with two separate buyers. The integrator is buying capacity and scarce skills. The end client is buying an outcome. The same message cannot do both jobs.
Who signs: head of partner or alliance management, delivery director, procurement lead for outsourced development, and the practice head for AI and data.
Tens of thousands of firms
the information services sector is counted in the tens of thousands, but the layer that subcontracts at real scale is a small fraction of it, and that shorter list is the workable one

Where the openings are

1
The decision is a document, not a meeting. Japanese enterprises approve an outside vendor by circulating a written proposal for consensus. So the first contact is not selling to the decision maker, it is arming an internal sponsor with something they can circulate without risk to themselves. That changes what an outreach message has to carry, and it is a design problem rather than a cultural barrier.
2
Two of these segments are named and published in full. The banks and the listed companies can be enumerated down to the individual institution. Most competitors work the same handful of famous accounts and leave the regional and mid-tier institutions untouched, which is the case where a complete named list beats a bigger one.
3
Language sets the sequence, not the market. The foreign-affiliated segment buys in English and the domestic segment does not, so they are two channels with two message sets rather than one campaign translated twice. Running them as one is the most common way a Japan entry stalls in the first quarter.
Built from public market data, counts banded deliberately. Counts are drawn from the national economic census, the government's own small and medium enterprise definition, the exchange's listing tables and the financial supervisor's published list of licensed institutions. Figures are current to the most recent published year and are banded because census years, survey years and listing tables do not line up with one another. Foreign-affiliated companies are surveyed rather than registered, so that segment is described rather than counted.
