Definitely go for it. Traveling solo in foreign countries is a great way to relax, have fun, and learn more about yourself through interacting with people from different cultures on their home turf - much different than on your home turf - as you need to adapt to their way of things. You also see things differently about your beliefs in a good way as others don't necessarily relate to the same indoctrination that has been fed daily by US educational system and MSM. History has multiple perspectives.
If Japan is on your radar, definitely purchase in advance the Japan Rail (JR) ticket (must be done from outside Japan) which costs about JPY 35,000 and is good for a week to travel anywhere. A single round-trip between Tokyo and Kyoto may cost JPY 25,000+ alone - Otaru (great sake and sushi at cheap prices), Sapporo, Noboribetsu (onsen haven) in Hokkaido, Tokyo, Kyoto, Hiroshima, Nagasaki, Yufuin (onsen haven), Kobe, and Okinawa. Germany, Rome, Florence, Venice, Bruges, Prague, Istanbul, Budapest, Krakow would be must-do's in Europe. Mykonos or Santorini islands in Greece. Reykjavik is a must-do. Bangkok (Pathumwan Princess is a great hotel), Phuket, Pattaya (Walking Street makes Bangkok look like minor leagues), Boracay, Hong Kong (similar vibe to NYC), Macau, Bali (Nusa Dua & Ubud areas; skip Kuta), Ho Chi Minh (take river boat to see the Cu chi Tunnels), Singapore (1-2 days to experience the quality of life)...so many other great places to visit in Europe and Asia, as well as Africa and South America.
There is always a risk taking any time off from work (especially a year) could cause issues coming back but in this case I think you would have a great experience, story, and learnings to convey to any future employer. You may also find one place upon your travels where you meet someone who might have an interest in the work you do for their company and may want to relocate to and decide to live for a while. Never know. Perhaps write a book about your travels and experiences...It's a once in a lifetime event and better to do it in your 30's while single. If I had that much saved at that time in my life it would be a no-brainer, especially given what I know now after living abroad over 10 years.
