The 3 things to know
Expect a pot of hot water at the end
After cold soba (zaru or seiro), staff often bring a small pitcher of hot water. It is soba-yu, the water the noodles were cooked in, not tea.
Pour it into your leftover dipping sauce
Pour the soba-yu into the tsuyu (dipping sauce) left in your cup. Don't pour it over the noodles.
Taste first, then sip it like soup
The tsuyu is salty, so taste before you drink. Then sip it as a warm soup to finish your meal.
Quick answers
What is soba-yu?
It is the hot water the soba noodles were cooked in. You mix it with the leftover dipping sauce and drink it as a warm soup.
What if no soba-yu arrives?
Not every shop serves it automatically, so you can ask with 'soba-yu o onegai shimasu'. It applies to cold dipping soba, not hot soba in broth.
Do I have to drink it?
The sources describe it as the usual way to finish a cold soba meal, but it isn't a strict rule. Taste first, since the tsuyu is salty.
