Where the name “Hanihohetoilo” comes from
“Hanihohetoilo” (ハニホヘトイロ) is the traditional Japanese name for the musical scale we know as do–re–mi–fa–sol–la–ti. Each person has their own note to play.
We believe in a harmony made of many different voices. That idea is at the heart of this community's name.
Children and adults alike, each respecting the individuality and talent of the other — learning and growing together. That's the community we're building.
Ha-Ni-Ho-He-To-I-Lo — Japan's own do-re-mi
Each note layers with the others to become harmony
