How to win new customers in Hokkaido's construction industry | Reaching 6,908 establishments in Sapporo

Published: 2026-08-14 / Author: Akio Nojima (owner of Nojima Giken / 20+ years in fax DM and business lists)
According to the 2021 Economic Census, Sapporo alone has 6,908 construction establishments, about 9.5% of the city's 72,730 establishments. Across Hokkaido they are spread even more widely, making construction one of the industries where in-person sales visits cost the most. That is exactly why it works to send one page first and only go to those who respond.

Hokkaido construction: "10% in Sapporo, the rest spread thin"

Sapporo has 6,908 construction establishments, the next-largest group in the city after wholesale and retail, accommodation and food services, and healthcare and welfare. Meanwhile, Hokkaido's construction companies are spread widely across Asahikawa, Obihiro, Kushiro, Hakodate and Kitami, and it is common for a single visit to take half a day to a full day..

With this structure, whether you cold-call in person or by phone, the cost per contact is nothing like on Honshu. Making the first contact by fax, then going only to those who respond, is the most rational order in Hokkaido.

Why fax still works in construction

It's not that "fax is old"; it's a tool that fits the way the recipient works.

When to send: Hokkaido construction decides before the snow melts

PeriodSituation on the groundSuitable content
Feb–MarPlanning and ordering for the next season get underway. The most important periodMaterials, tools, subcontracting, systems — things to decide before the season
May–OctSites come first. Offices are often empty and faxes rarely get readUrgent items, things that help in the busy season
Nov–JanSnow removal work and fiscal year-end. Some companies start movingNext year's investments, things related to expenses and year-end closing

If you send on a nationwide calendar, you'll miss the most important period for Hokkaido construction: February and March.

How to narrow the list (this is where the difference is made)

FAQ

Q. Can you make a list of Hokkaido construction companies only?A. Yes. We build it filtered by construction license category, number of employees, subprefecture and municipality. For fax DM, we deliver only entries that have a fax number.
Q. How many should I start with?A. We recommend starting with a few hundred and testing two versions of the copy. In Hokkaido the number of businesses per industry is limited, so if you send to everyone at once, you'll have no one left to send to next.
Q. When is the best time to send?A. In construction, planning for the next season gets underway in February and March, before the snow melts. Not missing this period is the top priority.
The establishment counts in this article are figures for Sapporo based on the "2021 Economic Census for Business Activity" (as of June 1, 2021) by the Ministry of Internal Affairs and Communications and the Ministry of Economy, Trade and Industry.
