Japan Enters a New Era: First F-35B Fighter Jets Land at Nyutabaru

A Milestone in Japanese Defense

On Thursday, August 7, 2025, three state-of-the-art F-35B fighter jets arrived at Nyutabaru Air Base in Miyazaki Prefecture. The arrival of these jets marks the beginning of a new era in which Japan’s maritime forces will gain true aircraft carrier capability for the first time since World War II. A fourth jet from the pilot batch remains temporarily in the United States, while four more are scheduled for delivery before March 2026.

From Helicopter Deck to Mini Aircraft Carrier

Although the F-35B is officially part of the Air Self-Defense Force, its future home will be the two largest ships in the Japanese Navy – the Izumo and the Kaga. Both are officially classified as “helicopter destroyers” to avoid political controversy concerning the constitutional ban on offensive weapons. In reality, they have been designed from the start with hangars, elevators, and deck dimensions suitable for fixed-wing aircraft.

World-Class Technical Modifications

Since 2021, both ships have undergone extensive renovations. Their flight decks have been reinforced with heat-resistant coatings to withstand the intense heat generated by the F-35B’s lift engine. Navigation systems have been upgraded, and layouts changed to incorporate refueling stations and specialized aircraft maintenance facilities. In 2024, integration tests were conducted on the Kaga, featuring about 50 takeoffs and landings – including night operations – to ensure full operational capability in all weather conditions.

A Strategic Signal to the Entire Pacific

With the arrival of the F-35Bs, Japan is sending a clear message to both allies and rivals throughout Asia. The jets’ ability to operate from both land bases and ships provides flexibility that strengthens Japan’s role in the region’s power dynamics. For many observers, this development is more than just a technological advance – it is a symbolic milestone marking Japan’s return to the era of aircraft carriers.
