- •Katayama said Japan will maintain its stance of balancing fiscal sustainability with economic growth and monitor developments in the Strait of Hormuz.

Japan's Finance Minister Satsuki Katayama said on Tuesday that the government will carefully examine potential tax incentives for retail investors in Japanese government bonds (JGBs) as part of a broader effort to widen the domestic investor base for government debt.
Speaking at a regular news conference, Katayama said it is important to make retail government bonds more attractive, according to Reuters. She added that there are still a number of issues to be worked through and that the ministry intends to discuss the matter carefully with relevant parties, including the ruling Liberal Democratic Party.
Japan already markets a product aimed at households, the so-called individual JGB, which is sold in units starting at 10,000 yen, but interest paid to individual investors is currently subject to a withholding tax of roughly 20 percent, so any preferential treatment would feed directly into the after-tax return those savers earn.
Katayama said the finance ministry has already received a range of opinions on a scheme aimed at retail JGB investors and expects additional tax reform requests on this front. Such requests typically feed into Japan's annual tax overhaul process, in which the ruling coalition finalizes an outline around December for changes that take effect from the fiscal year beginning in April. She declined to comment directly on budget requests for fiscal 2027, saying only that the government will focus on key policies designed to support economic growth in that budget.
She said Japan will balance fiscal sustainability with economic growth and will communicate that stance clearly to markets as the budget process develops.
The comments come as Japan continues to face upward pressure on long- and super-long-dated government bond yields, a trend that has been linked in part to speculation over the government's expansionary fiscal stance and reports about the shape of next year's budget. The Bank of Japan, for years the largest single holder of Japanese government debt, has been reducing its monthly bond purchases as it normalizes monetary policy, and the expanded NISA program that took effect in 2024 gives households tax breaks on stocks and investment funds but does not extend them to government bonds. Against that backdrop, greater retail participation in JGBs could, over time, provide an additional source of demand for government debt beyond domestic institutions and the Bank of Japan, although any tax changes would first need to move through discussions within the ruling party.
On foreign policy, Katayama reiterated that Japan's position remains unchanged in hoping for an early reopening of the Strait of Hormuz. She said Tokyo will respond appropriately to developments in US-Iran peace talks, given the implications for the broader international community.
The remarks add little new to Japan's established diplomatic stance, but they underline that the government continues to monitor the situation closely because of the strait's importance to global energy shipping routes, on which Japan remains heavily reliant.
