Healthy Bento!

I went to Tokyo by for my business trip last week.
On the way back to my hometown, I bought a japanese food bento with green tea.
They It cost around 1000 yen. (It, is used because you said "a" food bento.)
I enjoyed eating them it in Shinkansen. (It, again because you are talking about the one you bought. Them means more than one.)
I believe eating Japanese food is healthy. ( I added eating to mean the healthy benefit is for people.)

It has lots of veggies and ingredients from the sea and mountains.
In addition Also, it uses requires less oil than western food.(I also like western food, of course.) (In addition, is used formally. Also is more common but you could use either. I changed uses to requires because I think you mean oil is used in the preparation of the food. Correct? You might also mean contains.) 

Some people doesn't don't like too much soy sauce taste, but I like it! (Doesn't means does not and people do not or don't.)
Japanese food "Washoku" was registered as an Intangible cultural asset recently. (As an, means, Washoku was registered as "something" and "an" means there was only one registration.)
If you have opportunities to come to Japan I hope you enjoy these this food. (This, because you are only talking about one food.)

Sounds delicious!
