How much summer heat do they need to ripen? I can see that as being a problem in many areas of Western Washington, especially in our more mild summers.
Yuzu are primarily used as a flavoring agent in the green stage like Limes, so our ability to ripen them is far less important than...say... A Mandarin (some of which we can also grow, but is more challenging to ripen)
Edit: Arctic Frost Satsuma for example, should rarely experience dieback from sub 10 degree nights and grow back the next year... But to get it to ripen outdoors would require serious microclimate hacking. I'm talking deep rock mulch and maybe a rock wall to the north (or maybe a serpentine rock wall that curves around the west north and east)
I know, it's crazy, but I know people who've seen them grown outside! They can ripen here I've heard, though you can also use them unripened, as mentioned. Yuzu is primarily used for juice and for its rind, as Kyrt also mentioned. If anyone has anymore information/experience about growing yuzu or other citrus outside in the Northwest, please feel free to share it here. I'm going to try starting some seeds

I've wanted to try a breeding program with the aforementioned Arctic Frost Satsuma, Early St Ann and LA Early to try to produce a 10 degree F early ripener.
Easier said than done with these 'seedless' varieties
l digress...in terms of the happy lemon in Seattle, beyond good ol farmer magic I would attribute its success to being about 2/3 of the way up a SE facing hill with a house above it to the NW. The bottom of the hill has a grocery store parking lot and large arterial covered in black top, and this undoubtedly radiates heat. It also probably likes the boner view of Mt. Rainier.
