Begin at Hanazono Shrine in central Shinjuku for a calm, atmospheric early-morning visit; shrine grounds are usually accessible from early morning and it's a peaceful contrast to the later crowds. It's a short walk from Shinjuku Station East Exit and great for photos without people. (Open 24h for grounds).
Grab a quick Japanese-style bakery breakfast (melon pan, egg sandwich) at a nearby bakery to fuel the morning; bakeries open early (typically 7:00–8:00 onward). This gets you moving before the official attractions open. If you prefer sit-down, head to a café in the station complex.
Stroll Kabukicho while it's relatively quiet — check out the Godzilla head on Toho Cinema from the outside and get oriented for evening plans. Morning is a different mood and good for photos. (Outdoor, free).
Visit Shinjuku Gyoen for a large, peaceful park with lawns, traditional Japanese garden sections, and great cityscape contrasts; it opens at 9:00 (check seasonal hours) and is ideal in the morning for cooler light and fewer crowds. Entrance fee applies.
Take a direct/local train from a nearby Shinjuku station to Gotokuji to reach the famous Maneki-neko (beckoning cat) temple. Aim to arrive mid-morning so you're there during office/visitor hours when you can purchase figurines. Travel time ~30–45 minutes depending on route.
Explore Gotokuji, the origin site tied to the maneki-neko (beckoning cat) — the grounds are full of small lucky-cat figurines and it's a charming, photogenic stop. The temple office/shop is typically open 9:00–17:00 so visit during these hours if you want to purchase an official figurine.
Head back to Shinjuku to reach the next lunchtime stop; travel time depends on connection but plan ~30–45 minutes. Use this time to rest and plan the afternoon.
Enjoy a highly regarded vegan ramen spot within walking distance of Shinjuku (Shinjuku-sanchome area) — locals praise Ain Soph. Journey (and nearby vegan ramen shops) for flavorful plant-based broths and quality toppings. Most of these places open for lunch from ~11:30–14:30 and are popular, so arrive early or be prepared to wait briefly.
After ramen, take a short break at a nearby café — try a specialty matcha or drip coffee at Shinjuku-sanchome cafés to recharge before the afternoon. Many cafés open all day so this is flexible.
Visit the famous Cat Cafe Calico in Kabukicho to spend time with many friendly cats; it's one of Shinjuku's best-known cat cafés and a fun hands-on experience for cat lovers. Typical hours are roughly 11:00–21:00 (check current hours); plan on an hour to 90 minutes so you can relax and play.
Head back into Kabukicho to locate and photograph the famous 3D cat billboard — this large, attention-grabbing ad is a must-see for cat-photo fans and is best experienced in person (and lights up after dusk). Exact billboard location is in the Kabukicho commercial area near Shinjuku Station East; it's free to view.
Browse the department stores and arcades around Shinjuku Station (Seibu/Takashimaya/NEWoMan) for snacks, gifts, and city atmosphere as you move toward dinner. Shops typically stay open until 20:00–21:00.
Dine in atmospheric Omoide Yokocho for grilled skewers or pick a small Golden Gai bar with hearty small-plate options; both areas offer a classic Shinjuku nightlife scene. If you need vegan dinner options, request vegetable-based skewers or a nearby plant-based izakaya; Golden Gai bars often open in the evening (most 18:00–late). Expect small-plate prices per dish.
Return to Kabukicho to see the neon streets alive after dark and catch any illuminated signage (including the 3D billboard if you want second photos) — a lively, colorful stroll before heading to the observation deck.
Take the short walk to the Tokyo Metropolitan Government Building observatory for a late-night panoramic viewpoint; on clear nights you can spot Tokyo Tower lit up to the south. Observatories typically operate until 23:00 (last entry earlier — often 22:30), so this is a great final stop for a Tokyo Tower night view. Entry is free.
Finish with a late dessert or drink back near Shinjuku Station — many bars and cafés remain open late in Shinjuku, especially around Kabukicho and Shinjuku-Sanchome. Choose a rooftop bar if you'd like another distant look toward Tokyo Tower or a cozy bar in Golden Gai for a last nightcap.
Head back to your accommodation or the station; Shinjuku stays lively late, but many trains continue until around midnight — check the last train times if you're traveling outside central Tokyo. If you plan to stay out later, taxis are readily available.
