I'm not >>702 but reading that made me think; what is the normal word used for a sign? Like a traffic sign or a sign that indicates your current location. Also, what's the word for a sign in more a figurative sense like "There are no signs of infection".

On another matter, how do I say "Right now" with a nuance that says "but will most likely change in a near future".
Like: "Right now, nothing is more fun than Japanese(studies)." but that will probably no longer be the case in a few weeks/months.
