Novi, you are in Japan...Tokyo is just next to you..you are working on a Japanese national research institute...
Of course sometimes it is not perfect, just how normal life is...but zooming out, this is what you daydreamed about in your classroom or your lecture room...to go out, explore foreign land, to work amongst leading experts... you worked towards this back then... Now you are here, enjoy, be here, be excited about it, be thankful and grateful....

Whether this is what you want...well noone really knows what they want anyway...

So relax, enjoy, absorb...and love it...
