The Technicality of Awa Ai Indigo
The indigo industry in Tokushima, specifically known as Awa Ai, centers on the labor-intensive production of 'sukumo,' a concentrated form of fermented indigo leaves. The process begins with the harvest of the Polygonum tinctorium plant, which is then dried and winnowed. For approximately 100 days, the leaves undergo a controlled fermentation process in 'bed' rooms where temperature and humidity are manually regulated by turning the compost-like piles. Travelers visiting these workshops encounter the biological reality of the craft; the indigo vats are 'living' ecosystems where ash lye, lime, and wheat bran are added to maintain the pH balance necessary for the bacteria to thrive. The etiquette of entering these spaces is strict: visitors are expected to maintain low volumes to respect the focus of the artisans and are often required to wear specific aprons to prevent external contaminants from entering the fermentation pits.Lacquerware and the Temporal Dimension of Kagawa
In Kagawa Prefecture, the focus shifts to the temporal nature of lacquerware. The sap of the Toxicodendron vernicifluum tree is harvested in minute quantities, with a single tree providing only about 200 milliliters over its lifetime before it is cut down to allow for new growth. This scarcity dictates the pace of the craft. Slow travel participants in Kagawa are introduced to the multi-layered process of 'urushi' application, where dozens of layers are applied, each requiring a specific humidity level to cure properly. Unlike synthetic finishes, urushi does not dry through evaporation but hardens through a chemical reaction with humidity. This necessitates 'furo' or curing cabinets where the moisture is carefully managed. The immersive experience emphasizes the 'Mottainai' philosophy—a Japanese term expressing regret over waste—as damaged lacquerware is often repaired using Kintsugi, the art of joining breaks with gold-infused lacquer.Cultural Etiquette and the Henro Pilgrimage
Shikoku is also home to the 88 Temple Pilgrimage, or 'Henro,' a 1,200-kilometer circuit that serves as a framework for mindful movement. While traditionally a religious process, modern slow travelers use the route to connect with the concept of 'Osettai,' a local custom of giving hospitality or gifts to pilgrims. The etiquette of Osettai is detailed; the receiver is expected to accept the gift with gratitude, often reciprocating with a 'osame-fuda' (name slip), while the giver performs the act without expectation of repayment. For the mindful traveler, this interaction represents a break from the transactional nature of conventional tourism. When visiting temples, specific protocols must be observed:- Cleaning hands and mouth at the 'chozuya' water pavilion before entering.
- Bowing once at the 'Sanmon' (main gate) and staying to the side of the path, as the center is reserved for deities.
- Refraining from photography inside the main halls where icons are housed.
- Using a 'goshuincho' (stamp book) to collect calligraphy, which serves as a meditative record of the process.
