Reader JC asked about the upcoming analog-to-digital TV changeover on July 24 and how to prepare for it. The available options are so varied that it can be overwhelming to sift through and try to understand exactly what you need, especially if you can't read Japanese. We did some searching, and here's what we found.
If you own a digital TV that is compatible with digital terrestrial broadcasting (地デジ (chideji), or DTV) (most newer models are), then you're set — so long as you have a UHF antenna. If you live in an apartment building, the landlord or building owner will need to install a UHF antenna. In some locations with great reception you may be able to use an indoor UHF antenna instead. The only case in which an antenna isn't required is if you have cable, although you will need to confirm that your cable provider is providing digital terrestrial service.
If you do not own a digital TV, you can purchase a digital tuner (dejitaru chūnā) that is digital terrestrial-compatible (again, look for chideji). You will also need a UHF antenna installed at your home or building for this to work. And fortunately, albeit confusingly, there are a wide variety of options when choosing a tuner.
