Market size · Japan

Software and IT (Japan)

Information services and software sales in Japan, as the ministry surveys them.

Forge’s own description of what this market covers. A ruler for the size of a market, read once a year from the publishers below — it holds no sector and no company.

As its publishers state it

JPY 28.11 tn2026, an outlook · IDC · JPYJPY 33.32 tn by 2029 · 5.8 % a year — IDC’s outlook, not Forge’s

As of Sep 30, 2026 · 2 figures carried · never averaged, never Forge’s.

How big this market is, as its publishers state it

as of Sep 30, 2026 · 2 figures carried

1 publisher carried, 2026–2029, 1 with a published outlook, the furthest to 2029. Figures are the publishers' own, shown side by side and never averaged.

Last read Sep 30, 2026: wrote 2 figures and 1 stated rate.

Forge measures none of this. A statistical body publishes the history and its own outlook; Forge copies the figures with the sentence each came from and refreshes once a year, when the publishers do. A growing market says you are not building into a headwind — it says nothing about whether this application has customers.
