I went to a soba (noodle) making class in Tokyo almost exactly 10 years ago. It was wonderful, an excellent and knowledgeable teacher who spoke English beautifullly and great value for money - included the lunch I made as well as the rest of the noodles to take and share with family .
The school is still running classes.
It was just over 3,000yen in 2009, it’s now 4,000yen. Remains very good value.
