That term 'Takato soba,' subsequently traveled from Aizu to the Takato area where 'karatsuyu soba' became also known as 'Takato soba' and, on the contrary, the soy sauce-based sauce made of rich stock was referred to as 'amatsuyu' (sweet sauce).
その名が逆に会津から高遠地区に伝わって「からつゆ」蕎麦を「高遠そば」とも呼ぶようになり、それに対して出汁の効いた醤油味のつゆは「あまつゆ」とも呼ぶ。
