A friend in Japan handed me the Pharma-Act Japanese hair conditioner bottle beneath by Kumano Comestics. I don't know a word of Japanese. Thus please see the question in the title.
An interesting variant is when you have a bottle that is already in use and want to find out if its nozzle can be locked (because, say, you forgot, or somebody else put the bottle to first use).
In this case, unscrew the whole cap, point the nozzle back into the bottle, press down on the pump mechanism and try to lock the nozzle by turning it right. If it stays down, it is obviously lockable.
The advantage of this hack is, you did not spill and waste any content of the bottle, as you poured it back into its own bottle. The same technique is useful when packing a pump bottle for traveling.
