Zaru soba at Naniwa Okina in Osaka... probably the best soba I've tasted. The handmade soba noodles had lovely firm texture and bite. The tsuyu (dipping broth) was nicely fragrant of a good dashi, and not overly salty. The restaurant was awarded Michelin bib gourmand status for obviously delicious reasons.
The location is a bit of a walk from any of the nearby stations. We arrived in the early afternoon and were the only ones there, but a couple other parties showed up by the time we left. I had read that it can be busy around lunchtime.
Would definitely return on any visit to Osaka.
