When we were planning our trip to Osaka, I tried not to go overboard with the itinerary the way I did it for our 2010 Tokyo-Kyoto trip. (When I jammed so many things to do in a span of a single day without taking into account the fact that we were going to be in a new city where we don’t speak the language or know our way around its public transport system. Brilliant.) We had three whole days to spend in Osaka after arriving late in the evening (the rest of the trip was spent in Kyoto and Nara) and thankfully managed to see some sights, gorge on the local food, and not get blinded by the wild neon lights.
1. Eat! If there’s one thing the folks from Osaka are supposed to be good at it’s food. The country’s third largest city was known during the Edo period as “Japan’s kitchen” and it seems they’re still living up to it in some way as they keep serving great food. And some of them won’t break the bank, too. Have takoyaki while you’re walking around (there are lots of places to get it–from train stations to Dotonbori), teppanyaki for a proper dinner, and drinks with okonomiyaki (Mizuno in Dotonbori gets a pretty long queue), or kushiage (Kushikatsu Daruma has several restos in Dotonbori and Kita-ku).

Hankering for ramen? Look for a branch of Ichiran and line up for some solo session (you get your own booth) with ramen
2. Visit the castle and the grove. Osaka Castle is probably the city’s most recognizable landmark. It’s been destroyed and rebuilt through time, so the one standing there now where all of us tourists get our pictures taken is not a faithful replica (entrance fee, JPY600).
If you don’t find that impressive, the grounds around the castle still make it worth the visit, particularly during spring when the Plum Grove turns into this dreamy cloud of pink blooms lining several paths or when the Nishinomaru Garden overlooking the castle is covered by a cloud of pink cherry blossoms from its 600 trees.
