Praise for Seishundo
Seishundo is the only place in Kansai where you can enjoy a bowl of Inaniwa ramen, the creation of Youetsu Sato from Akita Prefecture’s Yuzawa City. Through our noodles, we aim to not only create a bowl of deliciousness but also an opportunity to meet new friends.

Seishundo History


I eat ramen for the first time and become obsessed by its charm.


Watching “Tampopo (Ramen Western)” written and directed by fellow Ehime resident Juzo Itami, I am overpowered by two forces of amazing power: love and ramen. Ramen = Forbidden food!


During a school trip as a student at Uwajima Higashi High School, I decide to go on my first ramen ramen shop pilgrimage.
Marushin (my favorite shop) -> Haruki-ya -> Mintei -> Ramen Kazuki


During my university entrance examinations in Tokyo, I’ve all but achieved my list of ramen shop destinations.


I was given a wealth of advice from the Ramen shop owners in Osaka whom I really respect. At this point, I’ve eaten at over 2,000 ramen shops.
Tenroku Mush-Up opens!
Without giving up on my dreams of opening my own ramen shop, I decide to first study up on cooking and liquor.


“Nunpoko” (ramen shop) opens for the first time. This specialty ramen shop is brought to life at Tenroku Mush-Up during lunchtime. The shop’s business details are published in national newspapers.


“Strike-ken” opens for the first time. My dream shop becomes a reality! The debut is marked by an event at Tokyo’s Shinjuku Dai-Tsukemen Expo. Tenroku Mush-Up also participates in the Tokyo Ramen Show.


Strike-ken wins the second-place title in two categories in the Kansai Ramen Magazine Grand Prix.
Tenroku Mush-Up participates in its first international event and opens a ramen shop for a limited time only. Tenroku Mush-Up also participates in the World’s Most Delicious Ramen Competition in Los Angeles.


Seishundo opens on April 15, owner Masatoshi Ashida’s 39th birthday.

Tenroku Mush-Up participates in more than 15 ramen events around Japan.


Spring and Summer Koshien are introduced.


Tenroku Mush-Up pushes ever forward with achieving the goal of new restaurant openings.
