Tradition collides with pop culture in Tokyo, where you can reverently wander ancient temples before rocking out at a karaoke bar. Wake up before the sun to catch the lively fish auction at the Toyosu Market, then refresh with a walk beneath the cherry blossom trees that line the Sumida River. Spend some time in the beautiful East Gardens of the Imperial Palace, then brush up on your Japanese history at the Edo-Tokyo Museum. Don’t forget to eat as much sushi, udon noodles, and wagashi (Japanese sweets) as your belly can handle.

A coastal resort complete with hot springs, Atami has been a favorite vacation spot for Tokyoites dating back to Tokugawa Ieyasu.

The shrines and temples of Nikko have been recognized by UNESCO as a World Heritage Site. Here, you can visit the Toshogu Shrine, which dates from the 17th century and is a monument to (and the mausoleum of) Tokugawa Ieyasu, the founder of a shogunate that ruled Japan for 250 years. Travelers day-tripping from Tokyo generally focus on the sacred sites, but if you have extra time, explore the area’s beautiful waterfalls and lakes.

Puerto Princesa’s claim to fame goes way beyond its swanky beach resorts and dolphin-watching cruises.

The British colonial city of Ipoh had humble beginnings, but has blossomed into a beautiful cityscape that marries old-world charm with modern amenities.

Singapore is known as a bustling metropolis that also happens to be one of the cleanest and safest cities of its size in the world. (Just make sure you heed the local laws—something like spitting in the street might merely be considered rude in your hometown, but here, it carries a severe penalty.) You'll find historic sites like the Thian Hock Keng temple, superlative shopping (including gargantuan malls) and numerous beaches.

Just a speedboat ride from Singapore, Batam’s beaches and bars tempt visitors with dishes of chili crab, grilled lobster, and freshly caught fish. While travellers golf, snorkel, and spa-hop, the island’s traditional culture thrives in fishing villages built on wooden stilts.
