Ibusuki no Tamatebako

The Ibusuki no Tamatebako, "the treasure box of Ibusuki", is JR Kyushu's limited express from Kagoshima-Chūō to Ibusuki, the hot-spring town near the southern tip of the Satsuma Peninsula. It is built around the folk tale of Urashima Tarō, the fisherman who visits the Dragon Palace beneath the sea and comes home with a box he must never open, and Ibusuki claims to be where that story began. The cars are black on one side and white on the other, and when the doors open a white mist pours from above them.

The ride takes under an hour, non-stop, and nearly all of it is beside Kinkō Bay, with the volcano Sakurajima across the water. Seats on the sea side turn to face a long wooden counter under the windows, so the bay is the view for most of the way.

Three round trips run every day, and every seat is reserved.

The train leaves Kagoshima-Chūō, the Kyushu Shinkansen's southern terminus, from a platform reached up a staircase hung with photographs of the train. It runs south through the suburbs of Kagoshima on the Ibusuki Makurazaki Line, a single-track, unelectrified railway, and then comes out on the shore of Kinkō Bay.

Along Kinkō Bay

From here the sea is on the left almost all the way, the drowned caldera of an eruption about 29,000 years ago. Sakurajima stands across the water, 1,117 metres high and often smoking, and later the long shore of the Ōsumi Peninsula. The train runs straight through Kiire and along the sea walls below the cliffs to Nukumi. Near Miyagahama the island of Chiringashima comes into view offshore, and a few minutes later the train pulls into Ibusuki, about 52 minutes after leaving Kagoshima. Cabin attendants hand round a commemorative card and help with a photograph beside a dated panel.

The train

The Tamatebako is two KiHa 47 diesel railcars, 8060 and 9079, rebuilt at JR Kyushu's Kokura Works with interiors by the designer Eiji Mitooka. Car 1 is lined in teak, car 2 in southern-Kyushu cedar; there are swivelling seats at counters facing the sea, box seats for groups of three or four, sofas among bookshelves and a corner of child-sized chairs. A third car, KiHa 140 2066, was rebuilt to match in 2012 and is added on busy days, or stands in for car 1 or car 2 when one is away for inspection; it has no sea-facing counter. The line goes on beyond Ibusuki, by local train only, to Nishi-Ōyama, the southernmost station on JR, and Makurazaki.

Three round trips run every day, all non-stop between Kagoshima-Chūō and Ibusuki. Every seat is reserved, and seats cannot be reserved on board.

Ibusuki to Kagoshima-Chūō

Good to know:

• Which car. From 9 October to 30 November 2026 the spare car runs as car 1 every day, so only car 2 has the sea-facing counter seats and no box seats are sold. JR Kyushu publishes the formation calendar a month or two ahead.
• Shinkansen connections. Since 18 September 2026 the Kyushu Shinkansen has run more slowly between Kumamoto and Kagoshima-Chūō after the 2026 Kumamoto earthquake, and the connections have moved: the Sakura 401 arrives at 9:39 for No. 1, and No. 6 connects with the Sakura 768 at 16:09.
• Days from December. The train keeps running; JR Kyushu announces the exact days in mid-October.
• Without a reservation, local trains and Nanohana rapids run between Kagoshima-Chūō and Ibusuki through the day.

Times as of October 2026, from JR Kyushu's timetable of 14 March 2026. Check your date on JR Kyushu's Ibusuki no Tamatebako page (opens in a new tab).

You need the fare plus a reserved-seat limited express ticket, bought together: ¥2,950 one way for an adult from Kagoshima-Chūō to Ibusuki, with the seat fee varying a little by date. Seats go on sale at 10:00 one month before travel, online through JR Kyushu's reservation site and at JR ticket offices; the four-seat box seats are sold only at the offices. The bento box, filled with Kagoshima produce, must be ordered on JR Kyushu's website between a month and three working days ahead.

The trains are small, two or three cars, so book early for weekends and holidays. Fares checked October 2026 on JR Kyushu's Ibusuki no Tamatebako page; Japanese yen.

The Ibusuki no Tamatebako is a JR Kyushu limited express, and the JR passes cover it, reserved seat included. The JR Kyushu Rail Pass (Southern Kyushu) costs ¥12,000 for three days and the All Kyushu pass ¥22,000; the Northern Kyushu pass does not cover it. The Japan Rail Pass covers it too, at ¥50,000 for seven days. Book the seat at a JR Kyushu ticket office or machine, free with the pass; the Southern Kyushu pass allows six such bookings. Booking before you arrive, through JR Kyushu's pass website, costs ¥1,500 a section for a sightseeing train.

For the Tamatebako alone, a pass does not pay: a return is ¥5,900 and the three-day pass ¥12,000. It pays once the trip includes the Kyushu Shinkansen between Kumamoto and Kagoshima-Chūō, which the Southern Kyushu pass also covers, or another of the region's limited expresses; price those legs as single tickets before buying.

Ibusuki is the place to stay the night: the sand baths, Chiringashima and Lake Ikeda are all close, and the last Tamatebako back to Kagoshima leaves at 15:07. Kagoshima and Sakurajima make a day of their own at the other end.

Ibusuki is a hot-spring town of ryokan, the Japanese inns where dinner, breakfast and the bath come with the room, and several have sand baths of their own. In Kagoshima, a hotel at the station makes the 9:56 departure easy.
