Travel to Japan in February

Hi! I'm thinking of traveling to Japan in mid-February next year. I really don't want to go by myself but unfortunately most of my friends aren't able to go, or can't afford it at the moment.

I still really want to go but I'm nervous I'm going to hate being on my own. I've never traveled by myself either outside of traveling for work so I'm not sure if it's right for me.

If you have any advice or travel stories involving solo travel to Japan please let me know! Also please let me know if you did solo travel to Japan and absolutely hated it haha
