no to worry about 產後修身 while u are in tokyo la...
only for few days... u might regret it after yr trip if u don;t eat as much as u like..
there aren't too much such opportunity to visit Japan anyway...
If I am u.. I will have all the food I like la
I am sure bb stuff from Japan won;t be cheap la (for those good quality one) but you might get sth u can;t find in HK which might be a bargain lei
