About
Kenichi 'Ken' Iwaoka is a Tokyo native who brought his passion for ramen to Boston's Brookline neighborhood with Ganko Ittetsu Ramen, a Coolidge Corner destination for serious Sapporo-style bowls. What distinguishes Ganko Ittetsu from other Boston ramen shops is Iwaoka's commitment to supply-chain authenticity: his noodles come exclusively from Nishiyama, Hokkaido's oldest noodle manufacturer, air-freighted from Japan on a weekly basis. Broths are built from scratch using traditional Sapporo methods, with rich pork-miso as the flagship. The restaurant participates in the annual Japan Festival on Boston Common, connecting it to the area's Japanese cultural community. Karaage alongside the ramen bowls is a particular standout.
