Solo Trip to Japan (Dec 15–Jan 2) — Looking for Social Hostel Recos in Tokyo / Kyoto / Osaka

Hi everyone!

I’m travelling solo for the first time and I’ve chosen Japan as my destination. I’ll be there for 18 days — from 15th December to 2nd January 2026 — and plan to explore Tokyo, Kyoto, Osaka, Takayama, and Kanazawa. Since I’ll be there during Christmas and New Year’s Eve, I’d love any recommendations on places, experiences, or special events around that time.

I’m currently researching hostels in Tokyo and it’s honestly a bit overwhelming. I’m specifically looking for a social hostel where it’s easy to meet new people and make friends. I’m focusing on the Shinjuku and Shibuya areas.

Shortlist so far:

• Wise Owl Hostel Shibuya
• UNPLAN (pricing seems on the higher side)
• Bedgasm (not in Shinjuku/Shibuya, but looks great)

I’m also looking for similar social hostels in Kyoto and Osaka, so if you have recommendations for those cities as well, please share!

Would love your thoughts — especially if you’ve stayed in any of these hostels or know better options for solo travellers.
Also, if anyone else is travelling to Japan during the same dates, happy to meet and explore together!
