I've passed by this place a couple of times but never tried it because it always looked very busy. However, if you go to the second floor it was almost empty on a weekday morning. It filled up and became quite noisy in the afternoon though.

The large worktable on the second floor is a nice place to sit and work, but unfortunately this table doesn't have any power outlets. The WiFi works well though.

The menu is very large, with a lot of food and drink options. I tried the Zhuori Dry Curry, which was very tasty.

Overall I would say this is a good spot to work from in the morning and have lunch, but afternoons will probably be too crowded/noisy.

This Blue Bottle Coffee is located just around the block from Exit 1 at Minatomirai Station. Good natural light with windows all around. When the weather is nice the doors/windows are open, which is nice. There small tables, counter seats, and 1 large round table. Decent WiFi but no power outlets.

Korean style cafe serving shaved ice and playing k-pop music. It's a little hectic, but the 2nd floor window seats are great for working, especially in the morning when it's a little quieter, or if you put on your noise-cancelling headphones. The cafe wifi is a little slow, but you can use the Shinjuku Free WiFi instead, which was much faster. The menu does mention a 90-minute time limit, but it doesn't seem to be enforced (at least not on a weekdays).

A trendy hostel that is designed by the folks who did K5 as well. The cafe lounge space is open to public as well as the guests. There are some food options with coffee. The seats are not strictly for working but the atmosphere and the big window takes lots of sunlight so I like that than Citan where you get close to no sunlight in the cafe. One unfortunate thing is that there's close to no plugs to charge your devices, other than the one couch seat by the piano.

An interesting cafe located on the second floor of an office building. Once you enter the building take a right and you'll see a sign leading you up the stairs. The cafe space is split into two parts. A smaller space by counter, and a larger space half a floor up. It was surprisingly busy during the morning on a weekday.

There is WiFi, but I didn't see any power outlets. I didn't see any restrooms (but I'm sure there must be some restrooms in the building). Drink felt a little non-premium since it was served in a plastic cup.

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).

A good spot to work from near Akasaka and Akasaka-Mitsuke stations. Some tables and a long counter with power outlets.

I'm not quite sure if this is a permanent location or just a popup shop. Order on the ground floor, and then there are two floors of seating. It wasn't very busy when I visited on a weekday morning, however, the interior is very echoey, so if anyone is talking inside it feels noisy. There is a tiny restroom on the first floor.

A nice spot to grab a drink and get some work done. WiFi works well on the first floor, but wasn't really usable on the second floor. Staff was friendly and speaks good english.
