About this tour
When Ben from our team did this workshop at cofunia, a heritage farmhouse tucked into the Yamanobe Trail—Japan's oldest walking route—we got a proper hands-on lesson in fermentation and slow food. You pick either a kakinoha-zushi or onigiri menu and spend 3.5 hours preparing lunch from scratch using seasonal, foraged, and garden-grown ingredients. The setting is quietly special: 100-year-old timber beams, views over ancient burial mounds, and a real working kitchen where locals still cook. It feels less tourist theatre, more genuine apprenticeship.
Highlights
- Make sushi and rice balls from scratch, wrapping kakinoha-zushi by hand
- Learn koji fermentation techniques embedded in everyday Japanese home cooking
- Eat your own lunch on the grounds of sacred ancient mounds
- 100-year-old farmhouse retains original character and working kitchen
- Seasonal vegetables sourced from local farmers and the property's own garden
- Small, private group—feels like cooking with a Japanese friend
- No-fuss public transport nearby; accessible for all fitness levels
What to expect
Ben's day started early at cofunia: a weathered wooden farmhouse that doesn't announce itself loudly. The host walked through the menu choice first—kakinoha-zushi (salmon and pickle sushi wrapped in persimmon leaves) or onigiri (rice balls with miso and umeboshi). We chose the zushi route. What followed was methodical and meditative: learning how to shape rice, understanding why koji (fermented rice) changes flavour, prepping vegetables and the salmon, then the fiddly, satisfying work of wrapping leaves around each piece.
Some elements—the koji egg and pickles—come pre-made (a realistic nod to what fits a 3.5-hour window), but the core cooking is genuinely yours to do. Midway through, the host brought out context: how persimmon leaves were traditionally used to preserve food, why certain fermentation pairings matter to Japanese home cooks. By lunch, you're eating what you've made on the grounds, surrounded by ancient earthworks and quiet farmland. The pace never rushed; the teaching was hands-on, not lecture-heavy.

Good to know
This is fermentation and Japanese cooking done at a human scale—not a tourist factory. If you're curious about koji, traditional preservation, or just want to spend time with your hands in real food, it lands. The location is genuinely atmospheric, not manufactured nostalgia. Small group sizes mean the host can respond to how you work.
You'll need to commit to hands-on kitchen work for 3+ hours; this isn't a demo where you watch passively. Walking is minimal and flat, but the farmhouse is old and not fitted out with modern accessibility—worth checking directly if mobility is a concern. The nearest transport is public and walkable, but the site isn't in a central hub; allow buffer time. Winter mornings will be cold; dress warmly. The menus are seasonal, so availability depends on the time of year.
Lunch is included. Bring an apron (or use theirs), comfortable shoes, and a camera if you want photos before you tuck in. Group size is small and private. Peak season will be spring and autumn when ingredients and weather are optimal.
