Def consulting ended the year to March 2026 with just ¥854.1mn in sales, but reported an ordinary loss of ¥2.15bn and a net loss of ¥2.15bn. That is a severe mismatch between the size of the business on paper and the scale of the losses it recorded.
| Metric | Year to Mar. 2025 | Year to Mar. 2026 |
|---|---|---|
| Net sales | ¥619.7mn | ¥854.1mn |
| Ordinary loss | ¥426.5mn | ¥2.15bn |
| Net loss | ¥427.9mn | ¥2.15bn |
The cash flow summary shows why this was not merely a rough earnings year. Financing activities brought in ¥4.22bn, while investing activities used ¥3.31bn. By March-end, the company reported ¥2.58bn in total assets and ¥2.41bn in net assets, so the balance sheet also ended the year looking far larger than the revenue line alone would suggest.
Compared with the previous year, sales did improve from ¥619.7mn. Losses moved in the opposite direction. The prior year showed an ordinary loss of ¥426.5mn and a net loss of ¥427.9mn, both far smaller than this year's figures. The annual report summary also put issued shares at 72.6 million at the end of March, versus 29.3 million in the March 2024 summary data.
A separate internal control report adds some context to what the company says it is trying to manage. Def consulting describes itself as a consulting and digital asset treasury business, says it has no subsidiaries, and treated the whole company as its significant business location for financial-reporting controls. It also added fixed asset impairment and crypto asset valuation to the higher-risk processes reviewed, before concluding that internal control over financial reporting was effective at March-end.
For readers, the striking point is scale. Def consulting is still operating with a sub-¥1bn revenue base, yet the filings show multi-billion-yen losses and multi-billion-yen financing and investing flows moving through the year.
