Tabelog ratingKasahara (かさ原) is a tiny, ten-seat counter restaurant in Shinjuku that has become a pilgrimage site for yakitori devotees. The experience is a focused omakase menu built around rare Kyō-Tanba chicken, but what truly sets it apart is the chef's near-scientific approach to fire control. Skewers are cooked with such precision that the skin becomes paper-crisp while the meat inside remains lusciously rare and juicy. Many reviewers describe this mastery of heat and the resulting textural contrasts as nothing short of world-class.
Guests consistently praise the chest (mune) sashimi, which is lightly seared over straw, and the ultra-creamy white liver sashimi. Among the cooked skewers, the negimi (leek and thigh), tsukune (meatball), bonjiri (tail), and soriresu (oyster) are perennial favourites. The meal concludes with a choice of comforting dishes like oyakodon (chicken and egg on rice), chicken ramen, or yaki-onigiri chazuke (grilled rice ball in broth), all of which receive high marks. The intimate atmosphere and well-curated wine list are also frequently noted.
Diners should be aware of the restaurant's strict character. Reservations are exceptionally difficult to secure, with waits often stretching to a year or more. House rules are firmly enforced: photography and phone use are forbidden, and there is no written menu. Some find the service style formal and occasionally brusque. Drinks, particularly bottled wine, are expensive and can significantly increase the final bill.
Reviewers in 2024–2026 report the omakase course costs around ¥20,000, but the total spend is typically much higher. One guest noted a final bill of ¥35,000 including drinks, while another party of two paid ¥83,300 after ordering expensive wine. Expect to pay between ¥30,000 and ¥40,000 per person. For serious yakitori lovers, the exceptional quality and technique justify the price. For those on a budget or who prefer a more relaxed setting, it may feel like poor value.
