How to make and meet friends while working remotely in Tokyo?

Hi all,

I may be in a situation where I can work remotely for a while and was wanting to head over to Tokyo for a while (possibly 3 – 6 months?).

From what I gather, the best way to meet new people and friends is usually from within the work place, but if you have the option to work remotely, what are the best way to meet new people and go on activities?

I've looked at Meetup.com but it seems quite limited on what activities there are, maybe because it's more catered for the English speakers?

If I do go, I'm looking to stay near the centre of Tokyo such as Shibuya, Setagaya.

It seems like rent in these areas with full furniture (unsure if electricity and water is also provided) would set me around 80,000 yen per month for about a 20sqm apartment.

I'm not sure how big a 20sqm apartment is but I'm guessing it's livable since they're out for rent.

I'm just trying to do as much research as possible so I can make the most of my time there if I end up going.

My Japanese is probably elementary level so while I can speak it and have conversations, reading and writing is a bit rusty.

Would be great to hear how others experiences have been in making friends with locals and where to go to find events / sports etc.

And also if this question has been asked earlier, would be great if you can let me know what to search for here.

Thanks in advance
