The living price in Tokyo (Grocery)

I have been living in Tokyo for over a month now.

With my husband, I am trying to enjoy the life in Tokyo although we sometimes have been trouble in getting used to live in a foreign country.

Going to the market with my husband is my routine every weekend, so I also went this Saturday.

I bought various things, and total amounts was around 3,500 Yen.

I am not sure but, I feel that the cost of grocery would be similar, or less than Korea.

How do you think about it? Could you share your opinion by comparing to your region?
