A very interesting spot in Kita-Senju. It's about a 10 minute walk from the station. Apparently this is an old abandoned bowling alley that has been converted to an art space and cafe/bar. I was there on a friday afternoon and it very quiet, just a couple people chatting or working on their laptops.

I spent a day exploring Kita-Senju and this was my first stop. A large cafe not too far from the station. Very friendly staff. Unfortunately the menu doesn't have any tea. The walnut banana bread was very good. Excellent WiFi, but I didn't really see any power outlets (at least not at the large tables).

A combined Cinnabon and Seattle's Best Coffee. Located right in front of the 1b exit at Roppongi station. The second floor is large and spacious. Use the "free_seattles" WiFi network, which is very fast (password located by the dish return area). You can definitely smell Cinnabon upstairs, but the smell isn't too overpowering.

A nice, large Verve not too far from Roppongi station. Large outdoor seating area, some seating on the 1st floor, and even more seating on the 2nd floor. I saw some power outlets on the 1st floor (not sure about the 2nd floor). The WiFi "works" but it is quite slow.

A quite large café with plenty of space available even on a Saturday morning. Great view of the street from the window seats on the second floor. Sadly the guest Wi-Fi doesn't seem to work and there are limited power outlets.

A bright, airy atmosphere with spacious interiors and large windows providing ample natural light. There's an outdoor seating area perfect for pleasant days, and a large indoor space. For working the counter seats are definitely the most comfortable.

There is fast WiFi (but limited to 3 hours per device per day). Few power outlets. From Ebisu station it is only a ~10 minute walk using the Ebisu Skywalk.

Toilets are inside the DCM DIY shop, on the same floor, but a bit far away.

This library is just a minute away from the beach. Ground floor feels ok to tak calls since the staff at the entrance are chatting anyways. Upstairs were very silent and lots of school kids studying. There are a couple of phone booth you can book.

This Starbucks is right in front of the beach and you can see the ocean from the seat inside. There are a couple of seats with outlets but not all of them. Also, the bathroom was out of service. WiFi password is just shown on the counter so easy to connect and no issue of signing in to use like they do in other countries.

A very nice Japanese style location for STREAMER COFFEE. It was quite busy on a weekday morning, but got fairly empty later in the morning and around lunch time. Great WiFi, but I'm not sure about power outlets (I didn't see any at least).

This library is right outside of the Chatswood station and the area is full of Asian restaurants and big malls. There are plenty of tables and chairs around but during the day, most of the seats are taken by the local highschool students (edit - I realized it's exam week when I went). There are quite a few kids who are casually chatting but not in a loud manner. There is a glassed corner near the entrance where you would be slightly more comfortable taking calls. Also, if you need 100% privacy and quietness, they have one bookable phone booth. It is free for the library members but it would cost you $2.50 / 30 mins if you are not a member. You can talk to the staff to book a spot.
