Honmachi
Getting around
Honmachi sits at the heart of central Osaka as one of the main hubs on the Midosuji subway line, the north–south backbone that links Shin-Osaka, Kita, Minami and Tennoji. That position makes it a convenient base: you can reach much of the city's transport network quickly from here, and the Midosuji line is the one you will likely use most often. For most sightseeing, plan your day around the subway and rail network rather than buses or cars. Two connections show how the network fits together: the Osaka Castle area is reachable on the Chuo subway line (or from Kita via the JR Osaka Loop Line), and the Osaka Bay area is served by the Chuo Line or the JR Yumesaki Line. To travel beyond Osaka City into the wider prefecture, use the various JR and private rail lines.
Prepaid IC cards are the recommended way to pay for trains and subways: Icoca is the local card, and Suica or Pasmo cards from Tokyo are also accepted. These cards double as a handy payment card at convenience stores and elsewhere. The JR Osaka Loop Line is covered by the Japan Rail Pass, but activate a pass when you leave Osaka for long-distance travel rather than for cheap local trips. Buses are extensive but not ideal for short-term visitors, so you will generally find the subway and rail easier; highway buses are a separate option for longer journeys out of the city, such as to Miyazu, Amanohashidate and Mineyama, bookable through Japan Bus Online, with fares and vehicle facilities varying by service and announcements sometimes in Japanese only. Taxis are convenient but expensive — reasonable for short trips, late nights or luggage, though the subway and trains are usually cheaper and faster for everyday sightseeing. In practice, combine walking in the immediate area with short subway hops between hubs and attractions, treating walking as your link between stations and nearby sights. Osaka is served by both Kansai International Airport and Itami International Airport, so check carefully which one you are using; on the Osaka–Amanohashidate/Mineyama/Miyazu Liner service, the stop labelled "Osaka International Airport" is Itami, not Kansai. To get into central Osaka, the practical options are the rail and subway network or a taxi, and highway buses also serve the area with stops including Shin-Osaka and Itami Airport on the Miyazu Liner route.
Three days in Honmachi
Day one: Start in Honmachi, the central district whose name means "main town", and use it as your base for the trip. Honmachi sits on the Midosuji line, which links the main districts of Osaka, so you can ride it north to Shin and Kita or south to Minami and Tennoji. Spend your first day getting your bearings along that axis, and keep in mind that the JR Osaka Loop Line is another useful way to move around the city.
Day two: Give the day to Osaka Castle, in Chuo ward, and the green space around it. The castle is the city's best-known landmark, and the grounds make an easy place to walk. Return to Honmachi in the evening and eat in the streets around your base.
Day three: Head for Osaka Bay on the Chuo Line, changing to the JR Yumesaki Line where needed. If you would rather leave the city, buses run from Osaka to Miyazu, Amanohashidate and Mineyama, and seats can be booked through Japan Bus Online. For the airport, Kansai International Airport and Itami International Airport both serve Osaka, and the Miyazu Liner is one of the bus options.
