How do I 'read' an address in Japan? I'm looking for restaurants in Tokyo with addresses like 2-14-21 Yokohama

For example, I'm looking for a the Shin-Yokohama Ramen Museum with the address "Yokohama-shi, Kohoku-ku, Shin-Yokohama 2-14-21" , I'm uming the numbers represent streets or areas? I'm trying to find maps and directions to some restaurants that I've got addresses for like one in Ikebukuro with an address "Nishi-Ikebukuro 1-10-8" what do those numbers mean? Thanks in advance
