Japanese cities are the top destinations for Asia-Pacific travelers next year, Hotels.com told CNBC.
Tokyo was ranked the number one vacation spot, followed by Osaka in second place, eclipsing previous favorite Hong Kong, according to data compiled from the accommodation booking site. The cultural capital of Kyoto came in at tenth on the list.
The Travelers' Choice Destinations on the Rise survey from Trip Advisor this month also featured a Japanese city: Naha in the southern Okinawa province, ranked fourth in Asia and sixth worldwide.
As Asia-Pacific travelers continue to spearhead the boom in international travel, the industry can't afford to ignore their preferred destinations. The number of outbound trips from Asia rose 8 percent during the first eight months of the year, double the global average, IPK International said in its annual travel report released this month.
"As far as destinations were concerned, the majority of Asians (75 percent) prefer to holiday on their own continent," IPK said.
The weak yen is the key driving force behind Japan's attraction within the region, said Abhiram Chowdhry, Asia-Pacific vice president of Hotels.com.
"Japan has always been a popular destination, but given that it's now 15 percent cheaper for everyone coming into the country, it's becoming more and more popular."
Foreign arrivals into Japan increased 28 percent on year in the January-November period, according to statistics from the Japan National Tourism Organization (JNTO).
The yen has sharply depreciated against a basket of global currencies this year, underscoringPrime Minister Shinzo Abe's policies to revive the economy. It's chalked up losses of over 13 percent against the U.S. dollar, adding to last year's plunge of 20 percent.
Hong Kong, ranked first in 2013 and 2014, moved down to the third spot on Hotel.com's 2015 rankings. Chowdhry doesn't believe the decline had anything to do with the city's recent pro-democracy protests: "The Occupy movement didn't scare people off. We observed prices and occupancies in Hong Kong were pretty stable and now that the protests have eased out, I expect the city to remain strong."
Meanwhile, Seoul, ranked second last year, dropped to fifth place. However, the city appears set to climb back up on the list thanks to strong Chinese luxury tourism flows.
"We have been writing recently that the new TST − Tsim Sha Tsui, the Hong Kong neighborhood where many Chinese mainlanders make their luxury purchases − is Tokyo Seoul Taipei," HSBC said in a recent note, adding that Seoul is truly the epicenter of the new group.
The bank believes Chinese nationals could soon represent a third of luxury sales in Korea, a huge boost for Korean tourism, given that Chinese travelers represent the world's fastest-growing tourism source market, according to data from the United Nations World Tourism Organization (UNWTO).
Two Thai cities also made it to Hotel.com's 2015 rankings: Bangkok took fourth place and Phuket came in ninth. Thailand's tourism sector, which accounts for roughly 10 percent of gross domestic product, has taken a hit ever since a political crisis began in late 2013.
"Visitor arrivals declined by 10.4 percent on year in H1, as tourists stayed away amid a tense political environment, protests and sporadic outbreaks of violence," Capital Economics stated in a report.
However, the sector may finally be on the mend, with visitor arrivals growing by an average of 4.2 percent on year in October and November, Capital Economics added, led by a 63 percent annual surge in Chinese tourists.
