How to Spend a Rainy Day in Osaka: Things to Do and Eat

Osaka may be known for its vibrant street scenes and open-air food stalls, but even when the rain starts pouring, Japan’s third-largest city doesn’t lose its charm. In fact, there’s something rather cosy about exploring its indoor attractions, warming up with comfort food, and watching the city lights shimmer on rain-soaked streets. Here’s how to make the most of a rainy day in Osaka.

Dive into the deep at Osaka Aquarium Kaiyukan

When the weather turns drizzly, escape into the mesmerising world of marine life at Osaka Aquarium Kaiyukan, one of the largest aquariums in the world. Located in the Tempozan Harbour Village, the aquarium takes you on a journey through the Pacific Rim, with enormous tanks that recreate natural habitats. The star attraction? The massive central tank, home to a graceful whale shark gliding alongside rays and schools of colourful fish.

The soft lighting and soothing blue tones make Kaiyukan the perfect refuge from grey skies, and once you’re done, you can pop next door to Tempozan Marketplace, which has an array of shops and restaurants to explore without stepping back into the rain.

Shop and stroll underground

Osaka’s ingenious network of underground shopping arcades is a dream come true on rainy days. Head to Shinsaibashi-suji and Namba Walk, where kilometres of connected tunnels are lined with boutiques, cafés, and beauty stores. You can shop for Japanese skincare, try on trendy streetwear, or stop for a steaming bowl of ramen without ever seeing a drop of rain.

Step into Osaka’s retro side

Rainy days are perfect for slowing down and soaking up some nostalgia at Shinsekai, a district that oozes Showa-era charm. While you might want to dash between covered walkways with your umbrella, it’s worth it for a peek inside the Tsutenkaku Tower, where observation decks offer panoramic views of the city through misty clouds.

Don’t forget to stop at one of the old-school eateries serving kushikatsu. Deep-fried skewers of meat, vegetables, and seafood. The golden, crispy coating is the ultimate comfort food on a cool, wet afternoon.

Unwind in a Japanese bathhouse

There’s arguably no better way to embrace a rainy day than by soaking in a Japanese onsen or sento. Osaka’s Spa World in Shinsekai offers a sprawling complex of themed baths. From Roman-style pools to Japanese cedar tubs. All indoors and heated to perfection.

Spend a few hours unwinding in the steam, then grab a light meal at one of the food stalls inside. It’s the kind of self-care that turns gloomy weather into blissful relaxation.

Catch a show or get artsy

Prefer to stay entirely indoors? Head to Osaka’s National Museum of Art, located mostly underground, where you can spend hours admiring contemporary works in sleek, quiet galleries. Or, if you fancy something livelier, the Osaka Shochikuza Theatre in Dotonbori offers performances ranging from kabuki to musicals. A cultural treat that’s ideal for an evening when the rain refuses to stop.

Go cafe-hopping in Amerikamura

Osaka’s answer to Harajuku, Amerikamura (or “Amemura”) is brimming with quirky boutiques, record stores, and creative cafes that make it an ideal spot for café-hopping on a drizzly day. Pop into a cosy coffeehouse like LiLo Coffee Roasters or Streamer Coffee Company, and spend a few hours people-watching through rain-speckled windows while sipping expertly brewed coffee. Many cafes here double as art spaces or vintage shops, so you’ll never run out of things to admire between sips.

Spend an afternoon at Osaka Station City

Even if you’re not catching a train, Osaka Station City is worth a visit. This massive complex combines shopping, dining, and entertainment under one gleaming roof. Browse fashion boutiques in Lucua and Grand Front Osaka, catch a film at the Toho Cinemas, or enjoy a relaxed lunch at a restaurant overlooking the cityscape.

For a bit of calm amid the bustle, head up to the Tenku no Noen rooftop garden. It’s covered enough to offer shelter, yet open enough to enjoy the sound of the rain falling over the city.

Get lost in books at Tsutaya Books Umeda

Few things feel as comforting as browsing books while it rains outside. At Tsutaya Books in Umeda, you can do just that. Surrounded by shelves of beautifully designed volumes and curated lifestyle items.

The attached Starbucks Reserve cafe offers floor-to-ceiling windows, ideal for sipping coffee while the world outside turns misty and calm. It’s a small slice of serenity in the middle of the city.

Take a food class or cooking workshop

When in Osaka, Japan’s “kitchen of the nation.” Why not learn to cook like a local? Several cooking studios across the city offer okonomiyaki or takoyaki-making workshops, where you can roll up your sleeves and master these classic comfort dishes. It’s an interactive, delicious way to spend a rainy afternoon, and you’ll leave with a tasty skill to take home.

Osaka’s rainy day eats

Rainy weather calls for something hearty, and Osaka’s comfort foods hit the spot.

Takoyaki

These piping-hot octopus balls are a local staple. Try them fresh from a yatai or order a shareable platter at Takoyaki Wanaka or Kukuru, both known for their perfect balance of crisp and gooey.

Okonomiyaki

A savoury pancake packed with cabbage, meat or seafood, and topped with a drizzle of sweet sauce and bonito flakes. Pop into Mizuno in Dotonbori, where the cosy atmosphere matches the comforting flavours.

Ramen

Slurp your way through a bowl of rich, steamy ramen at Ichiran, where private booths make it easy to savour each mouthful while the rain patters outside.
