Being a pescetarian can make finding good food spots a little tricky sometimes, but definitely not impossible.
Japan is very meat-focused, so it helps to have at least a rough idea of where to eat if you’re vegetarian, pescetarian, or have any dietary restrictions.
So, here are my personal pescetarian-friendly recommendations to make your trip a little easier.

If you’re craving a comforting bowl of hot udon after a long day of walking, Hanamaru Udon is a great option.
It’s a popular chain restaurant that you can find in almost every city — or at least every city I’ve travelled to in Japan so far
I usually go for the Fried Tofu Udon (Kitsune Udon).
Just keep in mind that the broth contains dashi made from bonito flakes, so it’s pescetarian rather than vegetarian or vegan.
Another big plus: the restaurants are usually quite spacious, so I’ve rarely had to wait for a seat — which is perfect when you’re absolutely starving after sightseeing.

One thing you should definitely try in Japan is Japanese Curry.
Finding a vegetarian version, however, is not always easy, which is why I really like Coco Curry.
It’s a chain restaurant, but that also makes it a reliable option when you are hungry and want something quick, easy, and comforting.
You can find Coco Curry in almost every city, so it is a very convenient choice while traveling.
Since you can choose from 20 different spice levels, it’s also a great recommendation for spice lovers.

Wanting to take a deeper dive into Japanese culture and cuisine, I also really wanted to try an izakaya.
Finding one with vegetarian options, however, can be pretty tough, so I was glad to have found one in Tokyo.
To be honest, the vegetarian dishes are only a small part of the menu, but part of the charm of an izakaya is the whole experience:
the atmosphere, the drinks, and the lively setting.
The one I went to was Yakitori Torikizoku Tokyo Yaesu Exit Store.
Make sure to reserve at least a few hours in advance.
We went without a reservation and were lucky that a group was just finishing up, so we could take their spot.

I wanted to go to a sushi restaurant that locals actually visit and not only tourists go to.
That’s why I ended up at Kura Shushi.
At the branch I visited, me and my boyfriend were actually the only tourists.
You can order via tablet, and the sushi is freshly prepared and served to you at high speed.
There’s also a fun little raffle system: for every five plates you finish, you get the chance to win a small surprise.
The sushi was extremely good, and we may or may not have gone there three times during our trip…
Water and hot matcha are free, so really, what more could you wish for?

Eating pescetarian in Japan is not always the easiest, but it’s definitely doable with a little planning.
Tokyo, in particular, has a great mix of quick chain restaurants, casual local spots, and fun food experiences that can work well for vegetarian or pescetarian travelers. From comforting curry and udon to fresh sushi and even an Izakaya experience, you definitely do not have to miss out on Japanese food culture.
My biggest tip would be to check menus in advance, keep an eye out for vegetarian options, and stay a little flexible.
You may not always find a huge variety, but you can still eat really well and enjoy some memorable meals along the way.
