The Japanese Embassy in Egypt on Thursday issued an advisory for travelers to exercise caution taking flights to and from Sharm el-Sheikh following a deadly Russian airliner crash in the region last week.
While no airlines fly direct from Japan to Sharm el-Sheikh, some Japanese travelers visit the Red Sea resort via Cairo.
The advisory noted Britain's announcement on Wednesday grounding all British flights to Sharm el-Sheikh and the United States' instruction on Monday to its embassy staff not to travel to the Sinai Peninsula.
The Japanese Embassy advised "careful consideration about the use of aircraft arriving at and leaving from" Sharm el-Sheikh for "those planning to travel to Sharm el-Sheikh and those already staying there."
It said the cause of the plane crash was "currently under investigation by Egyptian and Russian authorities."
The Airbus A321, operated by Russia's Kogalymavia airline, departed from Sharm el-Sheikh on Saturday and was bound for St. Petersburg in Russia.
All 224 passengers and crew perished when the plane crashed in the Sinai desert about 23 minutes after taking off.
Meanwhile, Germany's Lufthansa airline group said Thursday that it had suspended its operations to and from the Sinai Peninsula until further notice. The decision affects two weekly flights, operated by Edelweiss and Eurowings, it said.
Lufthansa's group airlines have been avoiding flying over the peninsula since Saturday, it said, adding that Cairo was not affected by the change.
