I do not recommend big luggage like 29" to be carried to Tokyo. It is not my first time in Tokyo but a first for the family. Should have kept to smaller multiple pieces. 6 min from the Tokyo Metro station Itabashikuyakushomae. Taking this train to most of Tokyo locale like Shibuya is about 30 min with 1 train switch. I do recommend the 3 day Tokyo Metro pass if you are here for 3 days. The circle JR Yamanote line is recommended of you are staying close to the JR stations. Kazushi San's place is more like inner suburb of Tokyo. Try the Morris ramen store which is the neighbour. 3 convenience stores within walking distance for 24h. I recommend Big-A wider selection of food just 3 min walk up the street.
