I would eat fruit over soy products myself if you want to venture into a new world of good “normal” foods.
Soy products should be placed in a similar category as vinegar, which isn’t too far away from alcohol.
If you want to go out and eat once a month go ahead, but I didn’t eat any chinese food (closest thing I have eaten to japanese food) until 6 months into the diet, and that was just one time. It set me back about a week and not a few days, it was definitely a bad choice.
Even worse than the sugar in the foods is the large amounts of white salt…I couldn’t believe how salty the chinese food I ate was. I am unsure how salty japanese foods are, but if its even in the same ballpark, I would wait until the 6 month mark to test it out.
Also, when you eat out, I feel its best to save it for special occasions.
