Studying abroad in Tokyo has been one of the most exciting (and humbling) experiences of my life. Living in a massive, fast-paced city where trains run like clockwork and vending machines are always within arm’s reach has made me think more about how my daily choices affect both the environment and local communities.
From day one, I’ve aimed to travel as sustainably as possible. One of the biggest steps I’ve taken is walking to university every day-40 minutes each way. This isn’t a long journey for me, as I walk everywhere back home as well, but most people take Tokyo’s efficient metro, but even public transport leaves a carbon footprint. The International Energy Agency says it emits about 75g of CO₂ per passenger per kilometre. By walking, I avoid that completely and save over a kilo of CO₂ per week just on my commute.
Additionally, I’ve also avoided any type of private transport (such as taxis and rental cars). For sightseeing, I’ve joined guided tours, which are not only low impact but also a fun way to learn from locals (and ask things like “Why are the manhole covers so artistic?”). These decisions reflect ‘SDG 11: Sustainable Cities and Communities’, encouraging urban living that’s eco-conscious and people focused.
I’ve also tried to support small, independent businesses over big chains. Japan is made up of over 99% small and medium-sized enterprises, so spending my money at family-run restaurants and shops directly supports the local economy-while also providing me with some of the nicest Japanese food I have ever tasted. This aligns with ‘SDG 8: Decent Work and Economic Growth’, which emphasises the importance of inclusive local development. I highly recommend these family-owned businesses, the food tends to taste way better!
Now, you can’t live sustainably in Japan without figuring out the recycling system. Tokyo’s rubbish sorting rules are… thorough. Burnable, non-burnable, plastics, PET bottles, cans… It’s sometimes difficult to not mess it up. It was overwhelming at first, but I’ve learned follow this system like a local. There’s something kind of satisfying about knowing exactly where your waste is going, and it’s made me more conscious of what I consume. That’s ‘SDG 12: Responsible Consumption and Production’ in action for ya!
Tourism contributes to about 8% of global carbon emissions, so even as a student, I’ve tried to travel as responsibly as possible. Tokyo has shown me that sustainability is about making smarter choices. Walking more, supporting local businesses, and sorting my rubbish with insane discipline have become part of daily life.
This year abroad hasn’t only improved my Japanese; it’s changed how I think. I’ve seen how these small, consistent decisions really can add up and make a positive impact. And while I will eventually leave Tokyo, I plan to take these habits with me and do what I can for the environment whether big or small.
