Kaiyukan & Osaka Bay
Whale shark, harbour wind, then the neon canal
For families and rainy-day planners: the bay area is mostly indoors, all within a few hundred metres, and the subway takes you straight back to the lights.

Kaiyukan Aquarium
Chuo Line to Osakako, then 5 minutes on foot; be at the doors when they open around 10:00, since school groups arrive by 11:00. The route spirals down through eight floors around one central tank, the Pacific, where a whale shark circles with rays and tuna; the best view is from the lower floors where the crowd thins. Finish at the touch pool and the jellyfish gallery.
2 HoursCost: ¥2,500–3,000 - 2
Naniwa Kuishinbo Yokocho lunch
Next door in Tempozan Marketplace, the second floor is a mock-up of a Showa-era Osaka street with counters serving the city's classics: kushikatsu, okonomiyaki, negiyaki and steamed pork buns. Around 12:30 pick a counter and eat at the stools. The harbour-facing terrace outside is fine for take-away if the weather is kind.
1 HourCost: ¥1,000–2,000 
3Santa Maria harbour cruise
From the pier beside the aquarium, the Santa Maria, a replica of Columbus's ship built at twice the size, does a 45-minute loop of the bay past the container cranes, the Universal Studios shore and under the red Minato Bridge; sailings run roughly hourly through the afternoon. Sit on the open top deck. Winter afternoons are cold on the water.
1 HourCost: ¥1,500–2,000- 4
Tempozan Giant Ferris Wheel
The wheel by the marketplace takes about 15 minutes round and lifts you above the bay for the Akashi Kaikyo Bridge on very clear days and the whole harbour on any day; the see-through cabins have a shorter queue than you would expect. Time it for late afternoon, around 16:00, when the light goes gold across the water.
30 MinutesCost: ¥500–1,000 
5Dotonbori evening
Chuo Line back to Hommachi, change to the Midosuji Line, two stops to Namba, about 25 minutes in all. Walk the canal from Ebisu Bridge past the giant crab and the Glico sign, ride the slow Ferris wheel built into the Don Quijote façade for a view down the water, and eat takoyaki standing up before a proper okonomiyaki dinner. Trains run until around midnight.
1.5 HoursCost: ¥2,000–4,000

Tips
Chuo Line to Osakako, and an Osaka Metro day pass covers both directions; it also gives small discounts at the aquarium and the wheel.
The aquarium is a 2 km spiral of ramps and the bay is all flat promenade; comfortable shoes and a layer against the wind off the water.
Eat at Kuishinbo Yokocho, not the aquarium café; it is cheaper, better and part of the fun.
The whale shark passes the big window on the lower floors every few minutes; turn the flash off. The harbour glows from the wheel about an hour before sunset.
