The statement is assessed as highly likely to be true based on strong, consistent evidence from multiple high-authority primary sources. A news brief from Reuters directly confirms the exact figures, stating that ¥11.7 trillion in new government bonds were proposed to fund the ¥18.3 trillion supplementary budget for fiscal year 2025. This is strongly corroborated by an article from Nikkei, a leading financial newspaper, which reports on the same supplementary budget and notes that the new bond issuance to fund it would be in the ¥11 trillion range.An economic report from the Daiwa Institute of Research mentions a different, larger figure for bond issuance (¥28.6 trillion). However, this is not a contradiction, as the report specifies this projection is for the *initial* fiscal year 2025 budget, whereas the ¥11.7 trillion figure is explicitly for the *supplementary* budget. This distinction clarifies that the government made separate bond issuance proposals for different parts of its overall fiscal plan for the year. The statement in the query accurately reflects the proposal for the supplementary budget.The document regarding the Hiroshima Prefecture's budget is irrelevant as it concerns a local government's finances, not the national government's. A blog post also provides corroborating calculations but is considered a low-authority source. Overall, the direct confirmation from two of Japan's most credible news and financial reporting sources provides high confidence in the truthfulness of the statement.
