Seamus O'Hara - About this place
Exit Musashi Koyama Station East Exit, go straight through the lively Palm Shopping Street.
Turn right at Fuji Soba, then left at the first corner in the back alley, and you'll find an Irish pub with warm lights, just like a hidden gem in Ireland.






The interior, a renovated 40-year-old Japanese house, recreates an authentic Irish pub.
The owner's desire to create a space where 'adults and children can gather happily' is reflected in the interior, which offers a comfortable and relaxing atmosphere for adults, children, and dogs alike, while enjoying a foreign ambiance.










The pub always offers 5 to 7 types of draft craft beer, including 'Guinness Beer', carefully selected by the owner.
Among them, 'Guinness Beer' is a unique stout beer, characterized by its rich aroma from roasted barley, an exquisite harmony of bitter and sweet, and a velvety smooth head.
Its profound taste captivates many customers, making it a very popular choice.






Furthermore, to serve 'Guinness Beer' in its best condition, the pub is meticulous about everything from temperature control to pouring techniques.
Its quality is so high that it has received Perfect Pint certification from the original 'Guinness Beer'.
You can truly enjoy a supreme pint, a cut above other establishments, faithfully reproducing the authentic taste of Ireland.
Homemade Irish dishes that pair well with beer are also very popular.
The popular 'Fish & Chips' uses fresh cod sourced from a local fishmonger.
By mixing beer into the batter, a unique flavor and crispy texture are created.
This dish is a testament to the owner's commitment, with no compromises from ingredient selection to cooking method.
The owner's recommended 'Shepherd's Pie' is an exquisite dish that offers a perfect harmony of homemade meat sauce, rich in lamb flavor, and smooth mashed potatoes.
Minced lamb is slowly simmered into a special meat sauce, generously topped with carefully sieved mashed potatoes, and then baked until fragrant in the oven.
With one bite, the rich umami of the lamb and the gentle sweetness of the mashed potatoes spread in your mouth.
In addition, there is a wide selection of Irish dishes that pair perfectly with beer, such as 'Homemade Beef Jerky' whose flavor deepens with every bite, crispy 'Onion Rings' with beer-infused batter, and spicy 'Chicken Wings'.
Please try combining various dishes with beer to find your favorite pairing.




















In addition to beer, the drink menu also features a wide selection of cocktails and whiskies.
At 'Rinshinomori Park' near the pub, Kawazu cherry blossoms bloom from mid-February to mid-March, and you can enjoy Somei Yoshino, Kanhi cherry blossoms, Uwamizuzakura, and Hanamomo while walking your dog.

めちゃくちゃ楽しかった
バーテンダーの方が最高でした! 周りがワンコ好きの人が多いのも好印象!
ビールがとにかく美味しすぎます
こじんまりとしたバーでビールがとにかく美味しい。 フードはそこまで期待していなかったのですが、フィッシュ&チップがとても美味しく、他のフードもオーダーを受けてたからの手作りでこだわり感が伝わりました。 ワイワイ飲みたいなら1階、静かに飲みたいなら2階へ。どちらもワンコと一緒に過ごしやすい雰囲気です。
ビールをつぐ腕は確かだと思います
初めてギネスビールをいただいたのですが、泡がずっと消えずにびっくり!しかも泡がクリーミーで感動しました。マスターの腕の良さを実感しました。 常連の外国人のお客さんが多く1階は賑わっていました。一方、2階は私たちだけの貸切状態でした。 トイレが2階にあるため、トイレに行くお客さんたちは、うちのワンチャンを見ると声をかけてくれ、たくさん可愛がってもらいました。
楽しく酔えます
路地裏の隠れ家アイリッシュパブ。 ひとりでも大丈夫な雰囲気なので、わんこの散歩がてらにたまに寄らせてもらっています。 お客さんもみんな気さくで楽しい。わんこにもめちゃくちゃ優しくて歡迎してくれます。 ギネス、ドラフトビール、武蔵小山エールどれも最高! 料理も美味しいので、本場アイルランドの雰囲気を感じたい方は是非行ってみてください。
わんこが同伴できるアイリッシュパブた
マスターは気さくで面白い方です。 アットホームな雰囲気で一人でもフラッと立ち寄れます。 客は外国人も多く、皆わんこフレンドリー! ビールも美味しく、ふわふわのフィッシュ&チップス、燻製のジャーキー、チキンウインク食べるのが定番でパイントで何杯もいけちゃいます!
