While there is no rigid, formal dress code for visiting Senso-ji (Asakusa Temple), modesty and respect are the guiding principles for this active place of worship. You should aim for "smart-casual" attire that avoids excessive skin exposure. For both men and women, this generally means keeping shoulders and knees covered; tank tops, spaghetti straps, and very short shorts or mini-skirts are often viewed as disrespectful. In 2026, with the high UV index in Tokyo, many locals and savvy travelers opt for light, breathable linen or UV-cutting parkas from retailers like Uniqlo. Hats must be removed when entering temple buildings. A crucial practical tip: wear "nice" socks without holes, as you will likely be required to remove your shoes to enter the inner sanctuary or specific halls. Slip-on shoes are highly recommended to make the frequent shoe-removal process much easier as you transition between the outdoor grounds and the sacred wooden interiors.
