leanbean,
In Kansai (western part) area of Japan, food is seansoned light.
There isn't a strong flavor of soy sauce in dishes, salt is used more for seasoning.
You can also make stock w/ fish, vegetable, or meat bones and flavor the food which makes it taste like Japanese food.
Although those food and seasonings you have listed are used in many Japanese dishes, you are still able to enjoy food in Japan.
