All Nippon Airways Co. said Thursday it will raise fares for domestic flights by up to about 9 percent from March 7 to 29 due to rising fuel costs under the weaker yen.

The first major fare hike in six years is expected to boost ANA's fare income in March by some 2 percent from a year earlier. If costs continue to rise, fares will be increased further, ANA said.

Under the hike, the one-way Tokyo-Osaka flight fare will rise from ¥24,600 to ¥26,800.
