well, that's it for this week, but coming up next time... a vision of the future from 1970s tokyo. carmen climbs the nakagin tower to find out why capsule living was the japanese craze that never quite took off. look at this tiny bathroom! i'm not going to even attempt to go inside. wow! it still works? yes. there's hot water? no hot water. ooh, tough! don't forget, you can catch up with more of our recent adventures on bbc iplayer. we're on social media, too — just search for bbc travel show on facebook and instagram. until next time, from me and all of the travel show team here in melbourne, it's goodbye.
