The Japanese are very found of collecting one’s food as we know from the popularity of strawberry picking, blueberry picking, and sweet potato digging. The clam-digging season is from March to June, May and June being the most popular due to comfortable water and air temps. Families are well equipped with full wading gear, tents, picnic lunches and more when they hit the muddy beaches to dig for clams. Don’t worry you can show up with just sandals and a hat in most places. Most locations sell buckets (200-500 JPY), net bags (200 JPY) and digging rakes (200-500 JPY) if you show up without your gear!

Here are tips for clam digging that were taught to us by an “expert” Japanese clam digger.

Tip to Prepare for Clam Digging

  1. Determine what location you will dig at, and review the tide chart. Most places are open for digging a few hours before and after low tide about six hour window. Most locations close the end of June so check end dates on the websites.
  2. Layer your clothes and a change of clothes for the little ones. When we began digging in the morning it was cold, two hours later it was really hot. Also, you will get wet and sandy/muddy.
  3. Wear plastic sandals or shoes so your feet do not get cut from open and broken shells.
  4. Take a hat, sun protection and a bottle of water.
  5. Items necessary for clam digging: a bucket, a net bag, a clam digging rake (garden rake), small cooler for your car, some people had bathroom stools or small chairs, so they did not need to bend over the entire time.

  1. Dig in the shallow water areas – clams from that area will have less sand inside.
  2. Do not pick up clams that are lying on top of the sand. Healthy clams hide about 5-15 cms down in the sand.
  3. You do not need to dig very deeply about 5-15 cms
  4. Clams tend to congregate together so if you are digging and not finding any pretty quickly move to a new spot.
  5. Asari clams have rough shells not smooth. I was advised not to choose the ones that are smooth. (Honestly do not understand but went with the recommendations).

Tips for Transporting and Preparing Clams to EatLocations for Clam Digging around Tokyo/Kanto area

  1. Fill your bucket of clams or cooler with sea water to transport home. If hot, add some ice to the water. You do not want the clams to overheat.
  2. Once home take your bucket or cooler and store in a cool dark place for a minimum of six hours. The clams will spit out sand during that time.
  3. If when cooking a clam, it does not open when all others have discard it. Sick or dead clams sometimes do not open.
