It's challenging to declare a clear favorite between Nihachi soba and Juwari soba as they offer distinct tastes. Nihachi soba, with its wheat flour content, goes down smoothly and has a pleasant texture. On the other hand, Juwari soba provides the authentic taste and aroma of pure buckwheat flour, with a delightful chewiness. If you prefer an easy-to-eat soba, Nihachi soba is a good choice, while Juwari soba is perfect for those who want to relish the true essence and texture of soba.
