It was published in Hankyu line information magazine "TOKK"
Tatsuya's Kobe beef shigureni was introduced in the 10/15 issue of the free paper "TOKK", which is full of seasonal information about Kansai's private railways and Hankyu lines, in the section "New and Old Gohan's Confrontation"!
As a standard version that is still loved today, he added phrases that are perfect for shigureni, such as "low fat, plenty of umami, healthy and juicy traditional taste".
"TOKK" can be obtained for free at each Hankyu station, so be sure to check it out.
