OVERVIEW

T’s TANTAN Gransta Tokyo is a beloved vegan ramen shop inside the ticketed area of JR Tokyo Station. Located on Keiyo Street inside Gransta Tokyo, the restaurant’s address is 1‑9‑1 Marunouchi, Chiyoda‑ku, Tokyo. It is open daily from 10 AM to 10 PM and welcomes travellers and commuters alike. The bright, wood‑toned interior exudes a warm atmosphere and the shop is popular with visitors from around the world. Because it is inside the ticket gates, you may need to purchase a JR platform ticket if you’re not already travelling on JR lines.

All menu items at T’s TANTAN are completely plant‑based—no meat, seafood, eggs, dairy or honey are used. The noodles are made from wheat flour and soy milk, and the rich broths rely on sesame, peanut and vegetable stocks. Diners can swap out the wheat noodles for low‑calorie konnyaku noodles for a small surcharge.

THE RESTAURANT

T’s TANTAN was one of the first restaurants to offer proper vegan ramen in Tokyo. It specialises in dandan‑style (tantanmen) noodles, inspired by Sichuan dandanmian. The shop offers several styles of tantanmen, including:

• Golden sesame tantanmen (Kin Goma) – a creamy white‑sesame broth enriched with peanut cream. This is the restaurant’s signature dish and the peanut cream gives the soup a luxuriously rich texture.

• White sesame tantanmen (Shiro Goma) – a milder white‑sesame broth for those who prefer a lighter flavour.

• Black sesame tantanmen (Kuro Goma) – the only spicy option; the broth blends toasted black sesame with Japanese pepper, delivering a pleasant kick without overpowering heat.

Each bowl is topped with soy‑based minced “meat” and fresh vegetables, and the menu is clearly marked with allergens. You can add vegan cheese or vegan char‑siu (soy “pork”) for extra richness. Side dishes include all‑vegetable gyoza and a mini vegan char‑siu rice bowl, and a massaman curry or multigrain rice bowl topped with char‑siu and miso‑flavoured soy meat. Seasonal specials—such as cold tantan noodles in summer or mushroom‑based ramen in autumn—are offered alongside the permanent menu.

The restaurant operates on a quick‑service model. In the Tokyo Station branch, staff take your order at the table and serve your meal promptly, although there can be brief waits during busy periods. Payments are accepted in cash or by card, and reservations are not required. Menus are available in English, Japanese and Chinese, making ordering easy for travellers.

DINING & RECOMMENDATIONS

A visit to T’s TANTAN is all about enjoying a bowl of vegan ramen that rivals its meat‑based counterparts. Prices are very reasonable: White sesame tantanmen is around ¥980, while Black sesame and Golden sesame bowls are about ¥1,100. For a small extra charge (¥100), you can upgrade to konnyaku noodles or increase the noodle portion.

If you’re unsure what to order, try the Golden sesame tantanmen; the peanut‑infused broth is creamy yet light and is a favourite among regulars. Pair it with a side of all‑vegetable gyoza or a mini vegan char‑siu rice bowl for a more filling meal, or order a seasonal set to sample limited‑time dishes and desserts. For those watching calories, substitute the wheat noodles for konnyaku noodles. And if you’re in a hurry, grab one of the takeaway bento boxes (soy meat char‑siu or vegetable gyoza) to enjoy on your train journey.

Getting to T’s TANTAN is straightforward once you’re inside JR Tokyo Station. Enter the Keiyo Street area near the Yaesu South exit and follow signs towards the Keiyo Line; the restaurant is located near the escalators. Keep in mind that because the shop is inside the ticket gates, you’ll need to hold a valid JR ticket or purchase a platform ticket if you’re not travelling on the train
