Alaska provides excellent vegan fare, with friendly staff and a nice a location.
My friends and I walked here from the Shibuya area, about a 20 min walk (and not exactly on a main drag for most of it, but don't get discouraged if you do the same!) As you get close, you'll start seeing some signs of life on the street again, with Alaska tucked away right behind a more main strip.
When we got there on a Sunday night, there was a decent amount of room and we were sat right away. The server explained our options really thoroughly, which include a few different sets (brown rice, bread, and one other I can't remember), which include soups and varying options depending on what you choose. There were also plenty of a la carte items that could be ordered.
I ended up choosing the brown rice set, which came with the rice (obviously), traditional salad, more of a small seaweed salad, and a soy meat karage dish. One of my friends also got this, and we were both really impressed by the flavors and quality in general. As a group, we also shared sweet potato fries (with a maple sauce--these went very fast), and the other two in our party got more bowl style dishes that they also raved about. On our way out, I grabbed a berry muffin that was really excellent--fresh and light.
The total for our meal was surprisingly reasonable, so would very much recommend as a great inexpensive vegan spot. Also, note too that it was open until 9pm on a Sunday, which was not the case for many of the vegan places we were exploring (a lot of which closed at 7pm or 8pm).
