Is Haneda or Narita better for Kusatsu?

Haneda is ~30 km closer and ~30 minutes faster. If your international flight lands at NRT, a direct transfer avoids a Haneda connection with luggage. If you can choose, HND saves a little time and money.

Can we stop at Ikaho Onsen or Gunma Safari Park on the way?

Yes. Ikaho Onsen is directly on the route (adds ~45 minutes for a stretch, ¥3,000). Gunma Safari Park adds ~2 hours — we usually bill that as a half-day add-on (¥15,000).

How does this compare to the Shinkansen + Agatsuma + bus chain?

Train+bus is ~¥13,000 per person and 5.5 hours with 3 transfers. Private car is ¥93,000 total (flat for up to 4 guests + 4 suitcases) — for 3+ guests per-person cost is close, and you avoid the bus stop at Naganohara-Kusatsuguchi.

Can I also book this from Tokyo Station mid-trip?

Yes — see our Tokyo Station to Kusatsu Onsen page (from ¥68,000). Same vehicle, no airport leg.

Drop-off at the Yubatake ryokan zone

By public transport, Narita to Kusatsu Onsen takes 5–5.5 hours with 3 transfers: Narita Express to Tokyo Station, Joetsu Shinkansen to Takasaki, JR Agatsuma Line to Naganohara-Kusatsuguchi, then a 25-minute JR Bus up the mountain. The Shinkansen + Agatsuma combination is tight — miss one connection and the next is an hour away. Direct buses from Shinjuku exist but take 7+ hours. A private car takes you directly from the Narita arrivals gate to your Kusatsu ryokan in about 4 to 4.5 hours via the Kan-Etsu and Joshin-etsu Expressways. Kusatsu is Japan's most famous sulfur onsen, centered on the Yubatake (hot water field) in the middle of the village — heavy with character, good for 2–3 night ryokan stays at Nishimuraya, Naraya, or Nakazawa Village. The final 30 km from the expressway exit is a winding mountain road; in winter, chains or winter tires are used. Best for first-time Japan onsen visitors who want a postcard ryokan experience without the brutal train chain.
