The page for my television appearance is online at last. It has some details about the programme, so feel free to take a look if you are interested.
The programme is half an hour long, and will be broadcast six times over the course of 24 hours on July 16th GMT. The times are on the programme’s page, and people in the UK should not forget to adjust for summer time; the 08:30 showing will actually start at 09:30.
So, how can you see it? This page gives instructions for seeing it on television. It does rely on you having an appropriate cable or satellite service, but the quality will be best if you can see it on an actual television. (Alas, a larger screen will be able to do nothing to mitigate the fact that I am in it.)
If that isn’t an option, you can also watch it online, on the NHK World homepage. There are also iOS and Android apps that allow you to watch it on appropriate devices.
Let me know if you have any questions about how to watch it.
