The evidence from the provided sources strongly and consistently supports the statement. Multiple independent financial and crypto news outlets (CoinDesk Japan, Yahoo! Finance Japan, and Coinspeaker) all report on a proposal by Metaplanet for a capital overhaul. A key and consistent feature of this proposal across all reports is the creation and issuance of a new class of preferred shares, referred to variously as "high-priority Class A perpetual preferred shares," "a new class of preferred stock to enable dividends," and "perpetual preferred shares named MARS and MERCURY." These technical terms all describe what can be accurately summarized as "Priority Dividend Shares," as preferred shares inherently have dividend priority over common shares.The articles refer to this as a "proposal" to be decided at a shareholders' meeting, with at least two sources noting the support of Norway's sovereign wealth fund, which indicates the proposal was formal, serious, and had significant backing. The final piece of evidence is the Kabutan portal, which is presented as the most authoritative source for official regulatory filings. This is where the definitive notice of an "approval" by the shareholders would be formally published. While the specific filing is not provided, the existence of this official channel, combined with the detailed and corroborating reports from credible news sources about the specific proposal, makes it highly probable that the event occurred as stated. There is no contradictory information among the sources.
