Pack the prepared vegetables into a clean crock or non-reactive container. Distribute the coarse sea salt evenly over and between the pieces. Place a weighted lid or press directly on the vegetables. Leave under weight for 24 hours. The vegetables are ready to proceed when they have released significant liquid and feel noticeably firmer to the touch.

Drain and discard the expressed salt liquid. Pat the vegetables dry. Combine the tamari, sugar, and mirin in a bowl and stir until the sugar dissolves. Add the konbu piece to the brine.

Pack the drained vegetables tightly into a sterilised crock or sealable vessel. Pour the tamari brine over the vegetables so they are fully submerged. Apply a weight to hold the vegetables beneath the surface. Seal the crock. This is where the dish lives or dies: every surface of every piece must remain in continuous, unbroken contact with the tamari — any vegetable exposed above the liquid will colour unevenly, absorb flavour only at the surface, and never develop the mahogany penetration throughout that defines tamari-zuke.

Store the sealed crock in a cool, dark place. Marinate for a minimum of 2–4 weeks; myoga ginger bud is ready at 2 weeks. Uri melon and daikon intended as premium tamari-zuke may be held for 3–4 months. At the minimum point, remove one piece and slice it thinly. The interior colour should be a uniform deep mahogany throughout — not merely darkened at the surface — and the flavour intensely savoury-sweet with full umami depth.

To serve, remove vegetables from the brine and slice very thinly. The concentrated character of long-marinated tamari-zuke is intended as a small accent alongside plain white rice; thick portions overwhelm. Do not discard the spent brine: add fresh tamari to the aged pickling liquid and use it for successive batches, deepening complexity with each cycle.
