A new favorite spot in Hiroo. I wasn't sure if it was workable, but I asked the staff and they said laptops are ok. Keep in mind there is a time limit, but only enforced when it is busy, mostly on weekends I guess. Nice vibes, very peaceful, good drinks. Some Mondays/Tuesdays closed (I think?).

If you're looking for a quiet spot in Shibuya then this is a bit of a hidden gem. It is located on the 2F of the OneFive Tokyo Shibuya hotel. Very fast WiFi, a few power outlets available, and decent drinks. The opening hours are quite limited though, so be sure to plan ahead.

This cafe is located on the 2nd floor of DDD Hotel. A nice quiet spot to get some work done. The counter seats overlooking the street below are a nice place to sit. The main downside is the price of drinks (quite expensive at ~800 yen for a coffee and ~900 yen for tea), and there is a 90 minute time limit per drink order.

Entrance of the building faces soi 2/1, there's a 711 on ground floor, the cafe is above at second floor. Seats along the back wall have sockets. Very clean bathroom. Almost completely empty on Thursday. They also have boardgames here.

A relaxing cafe ideal study or work. The first floor is quite narrow and dark. However, head up to the second floor instead, which feels bright and spacious. Plenty of power outlets and the WiFi is extremely fast (300+ Mb/s). There's a large workable, several small table, and a small sofa area. Some of the seats are however not very comfortable (especially the bench seating by the large worktable). Also, there's a smoking room on the 2nd floor and you may notice the smell if someone is using it (normally not a problem though).

Art gallery / cafe. It was basically empty on a weekday afternoon. There's fast wifi, some power outlets, and a decent selection of drinks.

A small and quaint cafe near Taipei City Hall. Both the interior and exterior are filled with green plants. The interior feels both modern and a little rustic, giving it quite a nice vibe. Luckily I had the entire cafe to myself on a (very) rainy weekday. Perhaps I was the only one that wanted to go out in the rain to find a cafe that day? The menu is quite large, with plenty of drink options, and although I didn't try any, the food sounded very nice (sweet and savory options available). Good WiFi, but slightly lacking power outlets (there was a power strip by the cupboards in the front seating area though).

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.

A nice cafe in a narrow alley in Seminyak. It is not crowded at all since it's a bit hidden from the main street. Only down side is that there is no toilets inside the establishments, but there are hostels and such nearby which will lend you a bathroom. Very fast and reliable WiFi.
