Iga shirouri teppō-zuke (melon stuffed and pickled in miso-tamari)白瓜の鉄砲漬け
In Iga, white melons (shirouri) picked in summer are cored, salted and sun-dried, then stuffed with miso and chopped salted vegetables such as ginger and shiso, capped and pinned with a skewer, and sunk in tamari soy sauce or miso. Yōkan-zuke matures in tamari for one to two years, while the milder Igagoe-zuke spends about two weeks in tama-miso and soy sauce.

At a glance
In Iga, white melons (shirouri) picked in summer are cored, salted and sun-dried, then stuffed with miso and chopped salted vegetables such as ginger and shiso, capped and pinned with a skewer, and sunk in tamari soy sauce or miso. Yōkan-zuke matures in tamari for one to two years, while the milder Igagoe-zuke spends about two weeks in tama-miso and soy sauce. Made in 5 steps over 14 days – 2 years. The longest step, sink in tamari or miso to ferment and mature, takes 14 days – 2 years (MAFF にっぽん伝統食図鑑 (traditional foods) 2026).
The melon is a container as well as the food. It is cored, sun-dried and filled with miso and vegetables before it goes into tamari and Iga's yōkan-zuke is matured in tamari for one to two years.
Yōkan-zuke (養肝漬)Matured 1–2 years in tamari; made by Miyazakiya, founded 1865.
Igagoe-zuke (伊賀越漬)About 2 weeks in tama-miso (soybean and rice both koji'd) and soy sauce, lighter in salt; made by Igagoe, founded 1873.
Safety
MAFF says the melon is matured for a long time to make it keep better. The melon is rubbed with salt and sun-dried until the water is gone before it is stuffed, and the milder Igagoe-zuke is made lighter in salt.
Iga households once pickled summer melons in home-made tama-miso to serve to guests. A story says the Tsu lord Tōdō Takatora kept it at Iga Ueno castle in the 17th century as field food to build up samurai spirit, which gave the name yōkan, 'nourishing the liver'. Miyazakiya's yōkan-zuke is also known for having been taken by a Antarctic research expedition.
