Oasis Management's Japan Activist Positions (2026)

Oasis Management Company Ltd. · Cayman Islands · EDINET code E31883

In a single week in May 2026, Oasis Management Company disclosed positions above 5% in five Japanese listed companies — IIJ, KYB, Kanadevia, Ichikoh and Nichirei — each filing stating the same purpose: "portfolio investment and important proposal activity." No single filing says "campaign." You only see it by stacking them.

What the filings show — and don't

Four of the five crossed their 5% threshold inside one week (April 24–30, 2026), several built through off-market blocks rather than slow open-market buying. One filing at a time, each is "a fund hit 5%." Stacked, it is one fund opening five fronts at once — including a ¥36bn stake in a large-cap infrastructure name (IIJ).

For Nichirei (2871), the fund goes further than the others: it states it is already making proposals and plans to raise its stake past 5%.

What the filings withhold: the actual proposals, the boards' responses, and whether these five are one theme or five coincidences. The filings reserve the right to act; they don't say what the act is.

Two of the five boards have since answered, on the company side: see what Kanadevia and Nichirei disclosed the same day this stake became public.
