The owner was a really great and kind woman, she was really responsive and it really ease up my first trip to Japan.
The closest station is only 2 minutes walk, you can't use your JR Pass here because the station is operated by Metro. (you need to walk 1.1 kilometer to the nearest JR operated station)
There are McDonalds, Seven Eleven, Family Mart, Lawson within 3 minutes walk.
A few other Japanese restaurant neaeby. (I recommend the ramen place near McDonald but you might want to use google translate if you want to order in detailed)
