The Japanese are well known for their habit of washing things under
running water rather than sticking a plug in it, such a wasteful
nation you will not come across (apart from the yanks).

They're light years ahead of us on energy efficiency, compared to them
in the UK we've only just stopped banging the rocks together:

The Takagi condensing multi-points, not available in the UK (yet) are "very"
efficient, and can return around 38 litres/min. Instant water heating has
become the norm in Japan now. It is a case of use low energy and store lots
of hot water taking up space, or use a lot of energy all at once, suing most
of the energy available down your gas pipe. They also developed
multi-points that can be installed outside to save space too.

The T-H1 at over 95% efficient and over 30 litres/min flowrate.
