High-Tech Toilets:

Also called washlets (ウォシュレット), these are toilets containing a bidet system, self-heated seats and automatic opening/closing of the toilet seat.

Floor-Level Drains:

These drains are commonly found in most Japanese bathroom floors to accommodate wet areas and for ease of cleaning.

Metal Taps and Fixtures:

Including stainless steel or brass, they are complex in their construction and need proper care and maintenance to look shiny and work as expected.
