All footwear is fine. Heels , flats, boots, sneakers, sandals. The only thing I don't see a lot of is older sneakers -but that doesn't mean don't do it. You just don't really see “well-worn” dirty sneakers outside of the running track or gym but .. it's not the end of the world if that's what you like.

Yes, you can absolutely wear sneakers in Japan, and they are actually the most "High-Fidelity" footwear choice for both locals and tourists in 2026. Japan is a "walking heavy" country, and most residents opt for stylish, comfortable sneakers from brands like Onitsuka Tiger, Nike, or New Balance for their daily commute. However, high-fidelity etiquette requires being mindful of shoe removal customs. In many traditional settings—including temples, ryokans, and certain high-end restaurants—you will be required to take your shoes off at the entrance (genkan). For this reason, many travelers prefer "slip-on" sneakers or shoes that are easy to unlace. Additionally, your socks should be clean and free of holes, as they will be on full display once your shoes are removed. While "streetwear" sneakers are ubiquitous in cities like Tokyo and Osaka, it is a high-fidelity sign of respect to ensure your footwear is clean and appropriate for the venue; overly muddy or worn-out gym shoes might feel out of place in more formal or spiritual environments.
