When the weather turns in Osaka
Umeda underground is a small country: Whity Umeda, Diamor and the Hankyu Sanbangai passages link four stations and several hundred shops, and residents still get lost down there. Namba Walk does the same job in the south. Kaiyukan, the Science Museum and the Museum of Housing and Living are fully enclosed. Den Den Town in Nipponbashi is electronics and hobby shops under continuous awnings.
Osaka's museums, and which one to pick
Almost all of the National Museum of Art lies underground on Nakanoshima, announced above ground only by a steel sculpture, and it closes Mondays. Next door the Nakanoshima Museum of Art opened in 2022 as a black cube and owns a Modigliani reclining nude. The Museum of Housing and Living rebuilds an Edo-period Osaka street indoors at full scale, lit on a cycle from dawn to night. Cupnoodles Museum in Ikeda charges no entry.
What to eat in Osaka
Kuidaore, eating yourself bankrupt, is the local self-description. Takoyaki and okonomiyaki are everywhere, but kushikatsu belongs to Shinsekai and the communal sauce pot carries one absolute rule: no second dip. Kuromon Ichiba Market sells sashimi and grilled scallops to eat standing, at tourist prices since the wholesalers went. Kitsune udon was invented at Usami-tei Matsubaya near Shinsaibashi and is still served in the same room.
What first-timers get wrong in Osaka
Stand on the right of escalators here; doing it Tokyo-style marks you out immediately. The Enjoy Eco Card buys a day of unlimited metro and city bus for 820 yen, dropping to 620 at weekends and on public holidays, which is worth planning your sightseeing around. From Kansai airport, Nankai runs to Namba while JR Haruka serves Tennoji and Shin-Osaka, so pick by which half of the city you sleep in.
What things cost in Osaka
Eight takoyaki from a street window run 500 to 700 yen and a kushikatsu skewer starts near 150, so a grazing dinner in Shinsekai stays under 2,000. Osaka Castle asks 1,200 yen and Nishinomaru Garden another 300. The day metro pass is 820 yen on weekdays and 620 at weekends. Hotels around Shin-Imamiya are the cheapest beds in any major Japanese city.
