Paper lanterns are ubiquitous in Japan with white or red being the most common colors. Small red lanterns hanging outside an establishment typically suggests that alcohol is served inside.
Temples also feature lanterns, with very large, red ones being found at some temples. These examples were all found while I was walking the Saigoku Kannon Pilgrimage this year.
The first photo was taken in the main hall of Kokawadera Temple in Wakayama Prefecture. The second is at Sefukuji Temple in the mountain in the south of Osaka Prefecyure, and the third is at Ishiyamadera temple at the southern end of Lake Biwa in Shiga.
The fourth is also in Shiga, at Miidera Temple, and the final photo is at Imakumano Kannonji Temple in Kyoto.
