There's a PRONTO cafe towards the East Halls. Just next to it is a large seating area with big windows offering lots of natural light. There's a lawson and restrooms nearby as well. The only free WiFi I was able to get onto was the Lawson Free WiFi (a bit slow, but works fine).

Inside the (tefu) lounge reception on the 2nd floor. There's a 1 hour time limit when busy. I think if you arrive in the morning on a weekday you can probably stay more than an hour. In the afternoon it filled up and was asked to leave after 1 hour.

Very work friendly chain cafe operated by Dotour. Interior is very nice, lots of single counter seats with outlets. Ambient music is quite loud but it is a piano song so not too disturbing. WiFi is the same as any other dotour cafes, you'd have to re-connect every hour. It would be better if the popup was as automatic as the Tully's one.e. But that's more on KDDI who provides Wi2. Props to USEN for better UX.

Another great place to work in Sapporo. Long opening hours, fast wifi, power outlets, quiet and comfortable environment. Really nothing to complain about.

Bakery and cafe located in the Maruyama Class shopping mall. Lots of good bread to choose from, drink selection is fairly basic though. The seating area is large and offers a lot of natural light. Most seats have power outlets. WiFi is decent.

Small Tully's inside Atre connected to the Akihabara station. Furnitures feels used and not the cleanest. You can get things done though. Bit sad as it's shaded and no sunlight comes in.

Another Tully's in an office area. Have lots of individual seats, some are partitioned for concentration. It's bit shaded so not the best view but very functional. Powers are plenty available.

Office building Tully's. Getcrowded around lunch. They pumped up the AC around lunch and got too cold. Plugs are limited to window seats. Wifi got also bit slow when people started to flock.

One of the best for work Tully's. It is often crowded with tourists and office workers but the turn turn over rate is quite high that you won't have an issue finding a seat. The plug availability is the best thing about this place that all of the window seats comes with anker sponsored plugs and USB cables. You could come here with just a laptop and work for the entire day. Food is available, toilet is clean, sit outside under the sun in spring, all good.

A nice little coffee spot not too far from Oimachi station. There's a small seating area on the 1st floor, and some more seating upstairs as well. I like the seats on the 2nd floor facing the windows. Power is available, I think WiFi might be available, but I'm not really sure. Staff was very friendly and welcoming :)
