Just do it
As stressful as it was I have no regrets about following through. A lot of people who want to travel and say they will do it later after they do x, y, and z. If you instead decide that traveling is really a priority for you then it is much more likely to happen. Rather than saying I would love to go ‘someday’ start saying you will go at the end of the year, or in two years, or three. It doesn’t matter how long it takes, it is still better to have a concrete date to work towards. At the end of the day most of us regular folk are always going to have something more sensible to spend their money on. For example I could say I want to travel but not until I pay my student loans or buy a new car or put a deposit on a house. Realistically if I go by that logic I won’t be able to travel at all in my twenties. Although it is a massive luxury and privilege to be able to travel internationally, it isn’t always merely something fun and frivolous to waste money on. Traveling can open your mind to new ways of life and it can teach you a lot about the world and yourself. If you want to travel you need to make it a goal, create a plan and actively work towards it. Waiting for a point in your life where you will have a couple of grand burning a hole in your pocket could mean waiting a very long time...
Traveling on a budget will mean shopping at local grocery stores, finding tasty popular chain restaurants, using public transport, window shopping instead of actual shopping and finding your own way around shrines and temples. If you are anything like me none of these options are really negative. I like visiting grocery stores, going to places that locals eat, being part of the daily commute, looking at all the crazy stuff in stores, and wandering around at my own pace. It is these experiences that help you gain a bit of insight into what it would be like to live in Japan.
I also believe Japan is one of the easiest places to get around as a traveler. The people are so friendly, the trains are amazing and there are English signs in the main centers. When my partner and I were first planning our trip we were considering booking through a tour company. We were worried about our lack of Japanese as well as our general lack of traveling experience. Nevertheless it turned out to be fun doing it under our own steam and not having to stick to a tour group schedule.
Another option for people who can’t really afford to travel would be doing a working holiday. You can find job listings here: https://jobs.gaijinpot.com/ . The Japan Exchange and Teaching (JET) Programme http://jetprogramme.org/en/ , working on Japans ski fields or at a Beach resort are also popular options https://www.boobooski.com/.
Plan your splurges
Experiences not things
The feeling of seeing something in a store in Japan that is really cool and not something you could find at home can be hard to deal with on a budget. If you are traveling on the cheap I strongly recommend leaving any shopping till the end of the trip. This gives you time to consider whether you really need it and whether you can actually afford it. The fear of not making it through the trip with enough yen should be enough to help you keep those purse strings closed. If you end up with a bit of cash spare at the end then go ahead and treat yourself. If not, remember that you are in Japan to be in Japan! This is not a shopping trip.
You will get sudden “OMG must buy!” feelings in Japan, its unavoidable. However I don’t regret leaving behind the things I didn’t buy , while I do regret a few of things I purchased (namely one too expensive cap that now resides in the back of my closet). I saw a lot of cosmetics I wanted to buy and had to remind myself that amazon Japan ships internationally. Another thing that can help you deal with this feeling of urgency is telling yourself you can always come back to Japan in the future. Trust me you will already be planning your second trip halfway through your first anyway.
Budget traveling means traveling to see and do things not just bring home a bunch of stuff. At the end of the day things are just things and memories are much more precious treasures to collect.
