Wadaya
About us
History of WADAYA
During a visit to Japan, founder Tomohiro discovered mazemen at a local restaurant. After experiencing the dish firsthand, he recognized its unique appeal and envisioned introducing it to a broader audience outside of Japan. Motivated by this vision, Tomohiro established MoguMogu USA in 2019 upon returning to the United States. Starting with its first location in West Los Angeles, the brand steadily expanded throughout Southern California, earning a reputation for serving authentic mazemen.
In 2025, following trademark-related challenges involving the MoguMogu name, the company rebranded as Wadaya. Today, Wadaya operates four locations across California, including three in Southern California and one in Northern California, continuing its commitment to sharing the authentic flavors and culture of mazemen with communities throughout the state.
Who is Tomohiro Wada
Born and raised in Kanagawa. Came to the US in 2011. Bored with plethora of ramen in South California. Tomohiro went back to Japan in 2017 in search for something bold and big. 2018 Tomohiro came back to California with a grand slam and open his first mazemen in 2019. As owner and Chef of Wadaya, Tomohiro is working on spreading the joy of experiencing mazemen across US.
What is MAZEMEN
Mazemen is a delicious Japanese ramen dish without any broth. Mazemen translates to "mixed noodles."
We serve our mazemen with thick, chewy noodles.
Mixed noodles offer a delightful opportunity to explore various flavor combinations. Without the presence of soup, you can experiment with different toppings, sauces, and seasonings to create personalized taste profiles. From spicy chili oil to tangy vinegar, each ingredient contributes to a new and exciting flavor experience.
Mixed noodles provide a canvas for customization, allowing you to tailor the dish to your preferences. You can adjust the amount of sauce, spice level, and ingredient combinations to create a bowl of noodles that perfectly suits your taste buds. This versatility makes every serving a personalized culinary adventure.
Additionally, with the inclusion of homemade vinegar, you can further enhance the enjoyment of the dish. Drizzle some of our homemade vinegar over the mixed noodles to add a tangy and acidic element that complements the umami flavors. The vinegar brings a refreshing brightness to the dish, creating a harmonious balance of flavors.
But the excitement doesn't end there! After relishing the mixed noodles, you can take it a step further by adding a serving of steamed rice to the remaining flavors in the bowl. As the rice soaks up the savory and tangy sauce, it transforms into a delectable companion to the noodles. The combination of the flavorful noodles and rice creates a whole new level of satisfaction, offering a delightful contrast in textures and tastes.
