Japan’s Liberal Democratic Party wants to issue a new category of government debt called “bridging bonds” to bankroll Prime Minister Sanae Takaichi’s sweeping domestic investment agenda. The proposal, submitted on May 28, covers 17 strategic sectors including semiconductors and shipbuilding.
What the LDP is proposing
The draft plan calls for bridging bonds to serve as a financing mechanism for expanded investment across sectors the party considers critical to economic growth and national security. The concept isn’t entirely new for Japan. The country has previously used similar initial funding instruments to finance green transition projects. This time, the scope is considerably broader, spanning 17 different investment areas.
The government is expected to evaluate whether bridging bonds should be folded into its medium-term fiscal blueprint, which is due in July 2026.
Takaichi, who became Japan’s first female prime minister on October 21, 2025, has made domestic investment expansion a centerpiece of her economic platform. The bridging bond proposal is the clearest mechanism yet for how she intends to actually pay for it.
