Rationale

In Protostars and Planets VII (April 10-15, 2023, Kyoto), major progress and insights in the fields of star formation, protoplanetary disks, and planet formation have been extensively presented and discussed. However, it has also become evident that connections between these fields are lacking, which preclude the establishment of a coherent scenario from star to planet formation. In this workshop, "Simulating Physics in Celestial Ecosystems: Star, Disk, and Planet Formation" (SPiCE), we aim to connect star, disk and planet formation, with a focus on computational simulations, to bridge the gap between these fields and foster cross-field collaborations.

Lunch places on Campus

There are a few on-campus dining places near the workshop venue. Please take a look at this map. Please be advised that there are only limited options for vegetarians and people with food restrictions. If you have food restrictions, we recommend University cafeterias (Ri-Yaku Shokudo and Midori Shokudo) and convenience stores. You can use the tables in front of the workshop hall for lunch.
The on-campus cafeterias and restaurants are all *cash only* except the convenience stores, so please bring some cash. Typically one lunch costs up to 1,000 JPY at these places. ATM is available in 7-11.

Travel To Sendai and Accommodation

Sendai is the capital of Miyagi prefecture, and is about 1.5 hour by Shinkansen from Tokyo. To Sendai, you can either fly into Tokyo (Haneda or Narita) and take Shinkansen, or directly fly into Sendai.

From Tokyo Haneda Airport (HND)

1. Take Keihin Kyuko (Keikyu) train to Shinagawa
2. Change to JR Yamanote (light green) line to Tokyo
3. Take Tohoku Shinkansen (green) to Sendai

From Tokyo Narita Airport (NRT)

1. Take Keisei Skyliner to Ueno (you need an express ticket)
2. Take Tohoku Shinkansen (green) to Sendai

From Sendai Airport (SDJ)

You can buy Shinkansen tickets from ticket vending machines at Tokyo or Ueno Station. The fastest Shinkansen services (Hayabusa and Komachi) are all reserved, and you need a reserved-seat ticket. Slower service (Yamabiko) has non-reserved seats.

Local Transporation

For local transportations in both Tokyo and Sendai areas, we recommend to purchase a prepaid IC card ("Suica", "ICOCA" or "PASMO"). You can buy one from ticket vending machines at train stations. There are special SUICA and PASMO for foreign travelers.

Accommodation

There is no hotel near the workshop venue, but it is only 10 minutes from Sendai Station. We recommend you to book a hotel near Sendai or Aobadori-Ichibancho station of the Subway Tozai Line (East-west, blue). Sendai is a reasonably big city and you can find many hotels at reasonable prices using web services.
