I'm a software engineer who's happiest with a one-way mindset and a backpack ready to go. Over the years I've learned that the difference between a stressful trip and a smooth one comes down to two things: a well-thought-out itinerary and paperwork that doesn't trip you up. I build both the way I build software — organized, tested, and made to actually work in the real world. The Japan itinerary I'm sharing here is the real route I traveled across Osaka, Kyoto, and Tokyo, and the visa cover letter is the same format I used for my own application. If you're planning your first big trip (or just want to skip the 40-browser-tab phase), I'm here to save you time and help you travel smarter. Grab a template, customize it, and go.
