Kanagawa is one of Japan’s finest prefectures for families: there are pirate ships, volcano steam vents, giant Buddhas you can climb inside, an aquarium where you can touch starfish, and a museum dedicated entirely to instant noodles. This guide covers the best family-friendly experiences across Kamakura, Yokohama, Hakone, and Enoshima — with practical notes on transport, timing, and what ages enjoy each activity most.
🏴☠️ Hakone: The Family Adventure Hub
Hakone Pirate Ship (芦ノ湖遊覧船)
The Lake Ashi sightseeing boats — styled as European galleons complete with cannons, masts, and pirate flags — are one of Japan’s most memorable transport experiences for children.
Route: Hakone-machi → Togendai (or Moto-Hakone, 25–40 min) Price: ¥1,200 adults, ¥600 children (6–12), included in Hakone Freepass Frequency: Every 30 min, 9:30–17:00 Tips:
- The Motomachi→Togendai direction gives the best Fuji view on clear mornings — check the forecast at hakonenavi.jp before departure
- Arrive 15 min early for the upper-deck bow positions; these go quickly
- The Hakone Freepass (¥6,100 from Shinjuku, kids ¥3,050) covers the pirate ship, ropeway, and Hakone Tozan train — ideal for a family day trip
Hakone Ropeway (箱根ロープウェイ) & Owakudani Volcano
The 4km ropeway above the Owakudani active volcanic zone is spectacular — gondolas pass directly over steam vents and yellow sulfur formations with Mt. Fuji behind on clear days.
Price: ¥1,800 adults, ¥900 children round trip from Sounzan Best for: Ages 5+ (check gondola safety requirements; young toddlers need to sit on laps) At Owakudani station: The kurotamago (hard-boiled eggs cooked black in the volcanic springs) are the unmissable local snack — the legend that eating one extends your life by 7 years is firmly believed by children. ¥600 for 5 eggs.
Note: The ropeway is suspended when volcanic activity increases. Hakone-Ropeway.co.jp posts current operation status.
Hakone Yunessun (箱根ユネッサン)
A large resort water park built around hot spring water — combining conventional pool slides and attractions with unusual theme baths (coffee onsen, wine bath, sake bath, green tea bath).
Access: Kowakien bus stop from Hakone-Yumoto Station (~25 min) Hours: 9:00–17:00 (water park section closes 18:00) Price: Yunessun water park area — ¥2,500 adults, ¥1,300 children (3–12) Combined ticket (Yunessun + Mori no Yu traditional bathing) — ¥3,500 adults, ¥1,800 children Best for: Ages 3–14; the slides and pools are age-segmented; toddler zones available
The wine bath and ramen-flavored bath are novelties popular with older kids; the large main pool has proper slides. The traditional onsen section (Mori no Yu) is a genuine retreat for parents while older children play. Bring swimwear for the Yunessun section (swimwear not allowed in the traditional baths).
🍜 CupNoodles Museum Yokohama (カップヌードルミュージアム横浜)
The world’s most popular food museum — dedicated to instant noodles, the Japanese invention that fed billions.
Access: Minatomirai Station (Minatomirai Line) — 8 min walk Hours: 10:00–18:00, closed Tuesdays Entry: ¥500 adults; free for children under 12 Make-Your-Own Cup Noodles: ¥500 per cup (separate, advance booking recommended at weekends) Chicken Ramen Factory: ¥700 per person, for ages 10+ (younger with adult)
Why it works for families: The museum combines genuine food history with hands-on experiences that hold children’s attention. The My Cup Noodles Factory workshop (design your own cup, choose soup flavour and 4 toppings from 12 options) takes 30 minutes and produces a noodle cup children keep as a souvenir. The Chicken Ramen Factory makes instant noodles from scratch — mixing the dough, rolling it through a machine, and flash-frying it.
The lower floor has a noodle bazaar with 8 Asian ramen styles for lunch (¥500–¥900 per bowl).
🦈 Enoshima Aquarium — Enosui (新江ノ島水族館)
One of Japan’s finest medium-size aquariums, with Sagami Bay as its backdrop.
Access: Katase-Enoshima Station (Odakyu Line) — 3 min walk; Enoshima Station (Enoden) — 5 min walk Hours: 9:00–17:00 (seasonal variation; summer until 20:00) Price: ¥2,500 adults, ¥1,200 children (3–12)
Highlights for families:
- Deep Sea Zone — bioluminescent creatures and deep-sea fish; the crown jewel is the live giant oarfish specimen (one of only a handful worldwide)
- Jellyfish Fantasy Hall — a darkened room with illuminated jellyfish tanks of every species; universally mesmerising for all ages
- Sagami Bay Large Tank — the main 1,000-ton tank holds sawfish, sea turtles, and sharks visible from both sides
- Touch Pool — children can handle starfish, hermit crabs, and small rays under staff supervision; morning sessions 10:00–12:00 have shorter queues
The aquarium’s terrace faces Enoshima island directly — Mt. Fuji is visible over the sea on clear days, making for a remarkable backdrop to the outdoor dolphin theatre.
🗿 Kamakura Great Buddha — For Kids
Kotoku-in temple (高徳院), Hase, Kamakura.
Entry: ¥300 adults, ¥150 children; interior climb — additional ¥20 (all ages) Hours: 8:00–17:30 (summer), 8:00–17:00 (winter)
The Great Buddha interior climb is Kamakura’s best-kept family secret: a narrow staircase inside the bronze figure rises into the shoulders, where two small porthole windows look out over the temple grounds. The interior space is bare bronze — dark, warm, and smelling faintly of metal — remarkable for children who grasp that they are inside an 800-year-old statue. The interior is only open from 8:00 to 16:30; it closes when the main gates are still open, so visit early to avoid missing it.
Kamakura + kids tips:
- Hase-dera (20 min walk from Great Buddha) has a cliff observation deck over the sea and a cave walk lined with thousands of small Jizo statues — excellent for older children
- Enoden tram — the slow coastal tram connecting Kamakura and Enoshima passes so close to residential houses that windows almost touch the carriages; children love this
🎡 Yokohama Cosmoworld (コスモワールド)
A free-entry amusement park in Minatomirai’s waterfront area, with pay-per-ride attractions anchored by the iconic Cosmo Clock 21 Ferris wheel (113m, ¥900).
Access: Sakuragicho Station — 5 min walk Hours: 11:00–21:00 (Fri/Sat until 22:00), closed Thursdays Entry: Free (pay per ride) Best rides for families:
- Cosmo Clock 21 Ferris wheel — bay views, 15 min rotation (all ages)
- Vanish! — roller coaster that drops underground into a pool (height restrictions apply)
- Wonder Amusement — indoor dark ride for younger children
Combined with the CupNoodles Museum (5 min walk) and Yokohama Red Brick Warehouse for lunch, Minatomirai is a full family day without needing to leave the waterfront area.
🦕 Hayashibara Museum of Natural History (林原自然科学博物館)
Hayama town, Miura Peninsula. A small but exceptional fossil museum with genuine dinosaur specimens from Central Asia — one of Japan’s best dinosaur collections outside of Fukui. The museum’s size (2 floors, 1 hour) is ideal for children before losing attention; the fossil prep lab is occasionally viewable.
Access: Bus from Zushi or Kanazawa-Hakkei Station (~25 min) Hours: 10:00–17:00; closed Mondays and Tuesdays Price: ¥300 adults, ¥200 children
🗺️ Kamakura Treasure Hunt Walking Tour
Provider: Several operators run guided and self-guided puzzle-walk versions across Kamakura (Enoshima Electric Railway sells a self-guided puzzle walk booklet at Kamakura Station — ¥600).
The puzzle walk sends families through Komachi-dori, the temple approach lanes, and the back streets of Kamakura solving riddles embedded in shop signs, shrine architecture, and hidden engravings. Each solved riddle gives the next location. Takes 2–3 hours, covers ~4km, suits children aged 8+.

Practical Tips for Families
- Pushchairs: Kamakura’s temple paths are cobbled and steep; a structured carrier or a lightweight stroller with solid wheels is better than a buggy. The Great Buddha and Hase-dera are navigable; the back-mountain hiking trails are not.
- Hakone Freepass (Kids): ¥3,050 from Shinjuku covers all children’s fares on the ropeway, pirate ship, retro railway, and Odakyu Romancecar. Calculate based on planned activities — it breaks even at 3–4 rides.
- Onsen with children: Most Hakone ryokan allow children; family private baths (kazoku-buro) are the ideal format — reserve at booking. The communal baths at most ryokan are adult-only or have strict quiet-time rules.
- Enoden timing: Avoid the Enoshima Electric Railway at peak summer weekends (11:00–16:00) — trains run every 12 minutes and queue times at popular stops extend onto the platform. Weekday or morning departures are comfortable.
- CupNoodles Museum booking: The My Cup Noodles Factory sells out at weekends. Book online at cupnoodles-museum.jp at least 3–5 days ahead.
