(CNN) — Ask most people where they want to go in Japan, and they'll likely reply without a moment's hesitation -- "Tokyo, duh."
Romantic Kyoto may come a close second, or tropical Okinawa, but the Japan bucket list rarely includes rough-and-tumble Osaka. It's Japan's third-most-populated city, yet one that is often overlooked by overseas tourists.
Bayside Osaka -- gutted by World War II bombing and rebuilt rapidly, haphazardly -- certainly lacks the picturesque architecture and alluring natural scenery of other Japanese cities. And its enduring role as one of Japan's economic command centers hardly seems like a reason to stir from your couch. So why visit Osaka at all?
We'll tell you why -- here are our top 10 reasons to head west in Japan:
1. Food worth going bankrupt for
Okonomiyaki -- have it your way.

Osaka's nickname -- Tenka no Daidokoro (the nation's kitchen) -- originally referred to its Edo Period status as Japan's rice-trade hub. Nowadays, it refers to its reputation as a gourmand's paradise. And okonomiyaki is arguably Osaka's most famous dish.
Somewhere between an omelette and a pancake, okonomiyaki is customized with a choice of meat, seafood or noodles to create an infinitely variable classic.
Other Osaka staples include kitsune udon (thick noodle soup blanketed by fried tofu) and hakozushi (sushi pressed flat in a bamboo box; an edible tapestry). Osaka's quintessential street snack? Takoyaki -- ball-shaped octopus fritters.
More adventurous diners may try tessa -- sashimi made from poisonous fugu, or globefish. Certified chefs are trained to leave just enough poison to numb the lips, not stop the heart.
2. Big-city flash, small-town warmth

Despite having nearly 3 million inhabitants, Osaka manages to blend cosmopolitan hipness with country charm. Hit the slick Umeda neighborhood for lively nightlife when the sun goes down or get elbowed in Namba department stores by ruthless housewives out for a bargain during the day.
Dine at ethnic restaurants in the entertainment districts or visit old-school sushi joints tucked away in the alleys.
If you crave urban diversity but don't feel like checking your sense of wonder at the door, Osaka is the place for you.
3. Time-machine trips

Your Edo-era time machine is really the Open Air Museum of Old Japanese Farmhouses in Osaka's Hattori Ryokuchi Park. Eleven authentic Edo farmhouses were taken piece-by-piece from various parts of the Japanese countryside and reassembled in this idyllic natural park setting.
Bonus: tourist traffic is relatively low, so it's easy to picture yourself as the star of a samurai movie as you drift between lush bamboo patches, creaky windmills and rustic barns.
4. Spa World
Spa World is billed as the perfect place to unwind.
Like a bizarre chimera, the Spa World complex in central Osaka rises from the smog and reveals its unholy blend of Japanese baths, Epcot Center and Vegas.
The "European Spa" zone features baths mimicking those of such places as Ancient Rome, Greece, Finland and Atlantis. We told you it was odd.
The "Asian Spa" pays tribute to Persia and Bali while including several kinds of Japanese outdoor pools. Spa World also has a gym, an amusement pool, whatever that means, a stone spa, a salon, a restaurant and, most helpfully, a hotel.
5. Korea's only a train ride away

The working-class district of Tsuruhashi is home to Osaka's Korea Town. The area clustered underneath the train tracks forms a labyrinth of Korean food and goods vendors.
Find all things Korean here, from hats plastered with Korean pop idols to pungent vats of kimchi or Korean wedding gowns. Locals instantly know they've arrived in Tsuruhashi when the train door opens and in floods the glorious smell of yakiniku, Japanese-style Korean barbecue.
6. The sky's the limit

In the late 1980s, civic leaders dreamed of creating a "City of Air" in Osaka in the form of four huge, interconnected towers in the Umeda area.
In the end, architect Hiroshi Hara settled on building only two in the form of the Umeda Sky Building, but what an impressive pair they are.
While offices occupy most of the Sky Building's 40-story towers, the rooftop is home to a "floating garden" observatory inside a glass dome suspended between the towers. Underground, there are markets and restaurants designed to recall early 20th-century Osaka.
The 173-meter Umeda Sky Building is one of the most recognizable parts of Osaka's skyline and, thanks to that rooftop observatory, you can actually take a stroll around it.
7. Puppets as art

It's not enough that Osaka has close to three million residents; it has to have puppets and dolls, too. That's because the city is the birthplace of Bunraku -- the centuries-old art of Japanese puppet theater. Even the crankiest theater-phobes will have to admit that the eerily limber and lifelike puppets are spectacular.
And the Kuidaore Taro -- a drummer doll dressed as a clown -- lives on Dotonbori, a bustling street in the heart of Osaka.
Originally found at Osaka's celebrated Cui-daore restaurant, the Kuidaore Taro moved to a nearby shopping complex after the restaurant closed in 2008. He -- like the giant mechanized crab welcoming diners to the Kani Doraku crab restaurant -- remains a totem of the city.
8. Water world

Few things are more terrifying than the sight of a shark in the water ... unless, of course, that shark is behind acrylic glass and reassuringly well fed.
That's the case at the Kaiyukan Aquarium in Tempozan Harbor Village. It's one of the largest public aquariums in the world and one of Osaka's most popular destinations, regularly attracting huge crowds to its walk-through displays of marine life.
After an afternoon at the aquarium, don't miss the chance to enjoy a ride on the 112.5-meter-high Tempozan Ferris Wheel for a great view of Osaka.
9. Show me the money

Osaka's reputation as a mercantile city goes even further back than its reign as the nation's kitchen; the port city has been Japan's commercial center for over a thousand years. So, what better way to Celebrate Osaka's economic prowess than by hitting its many excellent shopping districts?
DenDen Town (also known as Nipponbashi) is electronics heaven, while luxury-brand boutiques can be found in Shinsaibashi and Midosuji. Amerikamura is a trendy spot for hip vintage wear, and massive shopping centers can be found in Tennoji and Namba. All fun and much less crowded than their Tokyo equivalents.
10. The people
The perfect place to relax and socialize with friends.

"Love the city, hate the people" is a familiar quip that simply doesn't apply in Osaka -- unlike, say, Paris and, er, Tokyo.
Osakans are renowned for being open, brash and, above all, funny (Osaka produces a good chunk of Japan's comedians). But they have a nutty streak, too.
In 1985, Hanshin Tiger baseball fans tossed a KFC Colonel Sanders statue into the Dotonbori River, partly to celebrate winning the Japan Series and partly because they thought the statue resembled American Randy Bass, their star player.
When the Tigers suffered a long losing streak following the drowning of the Colonel, the Legend of the Curse of the Colonel was born.
Tigers fans took the curse so seriously, numerous attempts were made to recover the statue by divers and through dredging the river, before finally succeeding in 2009.
